CHAPTER 2: Introduction
2. Introduction
The Ultra2 LVD SCSI Host Adapter (our product code IC515C) is a highperformance Ultra2 SCSI (Low Voltage Differential) PCI-busmastering adapter
that functions as the interface between a SCSI bus and a PC’s PCI local bus. The
Adapter supports all kinds of peripherals compatible with SCSI-1, SCSI-2, Fast
SCSI, Ultra SCSI, or Ultra2 SCSI (LVD), including I/O devices such as SCSI
scanners and storage media such as hard-disk, CD-ROM, MO, tape, and removable
drives.
2.1 Features
• PCI 2.1 compliance. The Adapter meets all the latest electrical, mechanical,
and protocol specifications for the PCI bus.
• Full SCSI compliance. The Adapter is fully Ultra2 SCSI compliant, supporting
advanced features such as tag queueing, sync/async transfers, and
disconnect/reselect arbitration.
• Plug-and-Play support. The Adapter’s onboard ROMs can handle installation,
configuration, and booting without requiring user intervention.
• Use of only one system IRQ. The Adapter doesn’t hog your system’s limited
resources.
• 32-bit data transfers between the Adapter and the host PC at up to
133 megabytes per second in PCI burst mode. The PCI bus is a 32-bit bus;
when it runs synchronously at 33 MHz, the Adapter achieves a peak sustainable
operating speed of 133 MB per second.
• Regular (synchronous) SCSI data rates up to 80 megabytes per second, and
asynchronous SCSI data rates up to 10 megabytes per second.
• Compatible with all types of standard SCSI peripherals. Hard drives, CD-ROM
drives, tape drives, printers, scanners—it doesn’t matter what types of peripherals you want to hook to the Adapter. As long as they’re compliant with Ultra2
SCSI (LVD), Ultra SCSI, Fast SCSI, SCSI-2, or SCSI-1, they should work.
• Support for hard-drive capacities up to 8 GB. With the Adapter, MS-DOS®
hard-disk limitations can be extended from 1 GB to 8 GB.
11
ULTRA2 LVD SCSI HOST ADAPTER
• User-hardwirable, user-programmable, or automatic SCSI termination. You
can choose between hardwire-enabling termination on the Adapter,
programming the termation through its firmware, or letting the Adapter
handle termination automatically, eliminating the need to open up the PC
every time you need to make termination changes.
• Onboard BIOS supports Microsoft® MS-DOS. The Adapter has the necessary
software onboard to handle MS-DOS disk-drive operations without requiring
additional system-based drivers.
• Support for all other major operating systems. The Adapter includes drivers
for Windows® 98, Windows 95, Windows NT, IBM® OS/2®, Novell® NetWare®,
SCO® UNIX®, SCO UnixWare®, and Linux®.
• SmartSCSI™ Setup Utility program. You can use this firmware utility to
customize the Adapter’s configuration. Unless you need to hardwire
termination, you don’t have to set any jumpers at all.
• Built-in Integrated Scatter/Gather Engine (ISGE™). This hardware circuitry
heightens performance in all scatter/gather operations.
• 256-byte FIFO. The Adapter uses a 256-byte FIFO caching buffer to manage
PCI-to-SCSI-bus structure timing for data and command transfer.
• Command queueing. With this special feature, the Adapter can process as
many as 255 simultaneous SCSI commands.
NOTE
The README.TXT file on Driver Disk 1 might contain updates,
corrections, and additions to the information in this manual. However, if
you consult this file, you need to keep in mind that it was written by the
company that developed the drivers for use with the Ultra2 LVD SCSI
Host Adapter, and they use their own “INI-®A100U2W” code (rather than
“IC515C”) to refer to the Adapter.

CHAPTER 2: Introduction
2.2 The Adapter Illustrated
The Ultra2 LVD SCSI Host Adapter and its major components are shown in
Figure 2-1 below. You might want to refer to this diagram as you install your
Adapter (see Chapter 4). Figure 2-2 below that shows closeups of the Adapter’s two
SCSI connectors. The Adapter’s other components include:
• Jumper JP1: These posts are usually left open so that termination can be
firmware-controlled. Put a jumper on them to hard-wire termination always
ON.
• SE LED: Lights if any single-ended (legacy) devices are attached to the Adapter.
• LVD LED: Lights if any Ultra2 LVD SCSI devices are attached to the Adapter.
• ACT LED: Dark if the attached SCSI bus is passively terminated (which we
don’t recommend); lights if the bus is actively terminated (including forcedperfect termination).

ULTRA2 LVD SCSI HOST ADAPTER
3. Before You Install: Getting Started
3.1 The Adapter and the SCSI Bus
Your Ultra2 LVD SCSI Host Adapter performs busmastering and works with the
host computer to provide a means of control for the SCSI bus. By daisychaining
peripheral devices together, as many as fifteen devices can be linked to the Adapter
on the SCSI bus. The Adapter does not have to be placed in any particular physical
position on the bus, but because it doesn’t have two external connectors, it has to
be at the end of any all-external bus.
SCSI devices communicate on the bus using bus arbitration, which gives each
device an opportunity to use the bus based on the device’s priority (which is
determined by the device’s ID, not its physical location). The Adapter is factorypreset to ID 7, the ideal ID for it on a single-adapter bus (see the next section).
3.2 SCSI ID Numbers
Each internal or external device attached to the Ultra2 LVD SCSI Host Adapter, as
well as the Adapter itself, must have a unique SCSI ID number. This SCSI ID
determines priority when two or more devices are trying to use the SCSI bus at the
same time. No two devices can have the same ID; the SCSI ID uniquely defines the
device to the SCSI bus.
The Ultra2 LVD SCSI Host Adapter is factory-preset to use SCSI ID 7, which
gives it the highest priority on the SCSI bus; this ID number should not be
changed. IDs are usually assigned to each peripheral device at the factory, but you
will be able to set them to whatever you need them to be. This is usually done with
jumpers, DIP switches, or other physical controls; refer to each peripheral’s
documentation to determine how to set its ID. The key thing to remember is that
no two devices on the same SCSI bus can have the same ID; each ID must uniquely
identify a single device. Also keep in mind that a device’s SCSI ID does not
necessarily have any relationship to its physical location or its position on the bus.
For example, you can have an internal SCSI peripheral with ID 0, and an external
SCSI peripheral with ID 6. (Gaps in the number sequence don’t matter either.)
14
CHAPTER 3: Before You Install: Getting Started
A device’s ID number will reflect the priority it has on the SCSI bus; except for
ID 7 (reserved for host adapters), the lower a device’s number, the higher its
priority. So you should assign lower numbers to the devices that you will need to
access more frequently or at a moment’s notice, and higher numbers to less critical
devices. (8-bit “Narrow” SCSI peripherals must use SCSI IDs 0 through 6; 16-bit
“Wide” peripherals can be assigned IDs 8 through 15 as well.) Here’s an example
setup:

15
Primary hard drive
Secondary hard drive
CD-R drive
DVD drive
Floppy drive
Tape drive

:
(Other, low-priority SCSI peripherals)
When you assign SCSI IDs, we recommend that you leave the Ultra2 LVD SCSI
Host Adapter set for ID 7, its factory-default setting; use the Adapter’s firmware
configuration utility if you must change the ID number (see Section 4.6.4). If you
plan to boot your system from a SCSI hard-disk drive, set that drive to ID 0 for best
operation with most operating systems. (Most hard drives come from the factory
preset to ID 0.) Set the second hard drive, if you’re using one, to ID 1, and set
additional peripherals to sequentially higher IDs.
You can use the Windows 95 or 98 Device Manager to view the SCSI ID (and
other system-configuration parameters) assigned to each SCSI device attached to a
Windows 95 or 98 PC. You can do the same thing through just about any operating
system by accessing the Adapter’s SmartSCSI utility.
15
ULTRA2 LVD SCSI HOST ADAPTER
3.3 SCSI-Bus Length
Because of its inherent electrical vulnerability as a high-speed parallel interface,
the SCSI bus has definite distance limitations. With earlier versions of the SCSI
interface, the maximum length of the bus—the total distance from the terminated
device at one end to the terminated device at the other end—were normally
inversely proportional to the data rate, as shown below:
Max. Length
6 m (19.7 ft.)
6 m (19.7 ft.)
3 m (9.8 ft.)
1.5 m (4.9 ft.)
Standard
SCSI-1
Fast SCSI (SCSI-2)
Ultra SCSI (SCSI-3), up to 4 devices
Ultra SCSI (SCSI-3), up to 7 devices (narrow) or 15 devices (wide)
Ultra2 SCSI, however, can be extended to distances as great as 12 m (39.4 ft.) with
the proper cabling, as long as all of the devices are Ultra2 compliant, or even as far
as 25 m (82 ft.) to a single Ultra2 device. (If any attached devices are not Ultra2
compliant, the bus speed drops to that of the slowest SCSI interface represented by
a device on the bus, and the maximum distance drops to that of the most lengthrestricted SCSI interface represented by a device on the bus.) Remember that if
you attach both internal and external devices to the Adapter, the bus goes from the
last internal device to the last external device. To make sure you can run the
greatest possible distance, make sure to use cable with impedance of at least
120 ohms (do not use 90-ohm cable unless all of the devices you’re attaching are
non-Ultra2 LVD type); use high-quality twisted-pair cable with high-quality shielded
connectors for your external cable.
3.4 SCSI-Bus Termination
To ensure reliable communication, the SCSI bus must be properly “terminated.”
That is, the bus must be bracketed with networks of electrical resistors called
“terminators” that absorb the remains of data signals and prevent them from
echoing and interfering with fresh signals. Unless they are actually built into the
cables, terminators must be placed—or enabled, if the last devices have them built
in—at the two extreme ends of the SCSI bus. All devices that lie between the ends
must have their terminators removed or disabled. SCSI cabling is designed to be
connected in daisychain fashion, with no device on the bus being directly
connected to more than two others. No branching is permitted on the SCSI bus.
Refer to the example setups in Figure 3-1 on the next page.

ULTRA2 LVD SCSI HOST ADAPTER
Because the methods for terminating SCSI peripherals can vary widely, you should
refer to a given peripheral’s documentation for instructions on how to enable or
disable its termination. Here are some general tips about device termination,
though:
• Internal Ultra2 SCSI peripherals are shipped from the factory with termination
disabled; this setting cannot be changed. Proper termination for internal
Ultra2 peripherals is always provided by a built-in connector at the end of the
attached internal Ultra2 SCSI cable.
• On other kinds of internal SCSI peripherals, termination is usually controlled
by manually setting a jumper or moving a switch on the unit, or by physically
installing or removing one or more resistor modules on the unit.
• On external SCSI peripherals of all kinds, termination is usually controlled by
installing or removing a SCSI terminator, although some peripherals have
internal termination that you can switch on or off instead.
• Most non-Ultra2 SCSI peripherals come from the factory with termination
enabled.
As it is shipped from the factory, your Ultra2 LVD SCSI Host Adapter can
automatically enable or disable its built-in termination. If the Adapter senses that it
is at the end of the bus—for example, if you attach only internal or only external
SCSI devices to it—it will auto-terminate itself. If it senses that it is in the middle of
the bus—for example, if you attach both internal and external SCSI devices to it—
it will auto-disable its terminators.
If you would rather set the Adapter’s termination manually, you can go into the
SmartSCSI™ Setup Utility in the Adapter’s firmware (see Section 4.6.4) and
change the “SCSI Terminators” setting in the “Adapter Setup” menu. Switch from
“Automatic” to either “ON” (always ON), “OFF” (always OFF), or a combination of
“High bit ON”/“OFF” and “Low bit ON”/“OFF”:
• Set the high bit and low bit both ON if the Adapter is at the end of the bus, so
that only external devices or only internal devices are attached.
• Set the high bit and low bit both OFF if the Adapter is in the middle of the bus,
so that both internal and external devices are attached, and if at least one device
on each side (internal and external) is a Wide SCSI (68-pin, 16-bit) device.
• Set the high bit ON and the low bit OFF if the Adapter is in the middle of the
bus, so that both internal and external devices are attached, and if all of the
devices on either or both sides (internal and external) are Narrow SCSI
(50-pin, 8-bit) devices.
18
CHAPTER 3: Before You Install: Getting Started
NOTE
If you mix Wide and Narrow devices on the same side (internal or
external) of a SCSI bus attached to the Adapter, we strongly recommend
that all of the Narrow devices be attached to the bus closer to the
Adapter than all of the Wide devices. If you attach any Narrow devices at
the far end of the bus, beyond any Wide devices, you’ll have to be very
careful to terminate the Wide lines (Pins 51 to 68) of the last Wide device.

Alternatively, you can “hardwire” the Adapter so that termination is always ON by
installing jumpers on the Adapter’s circuit board. The most common application
for which you would hardwire-enable termination is this: installing multiple
Adapters in multiple PCs, but attaching them to the same bus in order to share
peripherals. In such situations, you might want to hardwire termination ON for any
Adapters that are on the end of the bus, so that you can turn off the computers in
which those Adapters are installed without losing termination power and disabling
the SCSI bus. If for this (or whatever) reason you do want to hardwire termination
ON, you need to install a jumper on the Adapter before you put it in your PC.
(Once this jumper is installed, it will override the termination setting in the
Adapter’s firmware.) The jumper should be installed at location JP1, as shown in
Figure 3-3 below.
Figure 3-3. Hardwiring termination.

ULTRA2 LVD SCSI HOST ADAPTER
3.5 Attaching Legacy Equipment
Your Ultra2 LVD SCSI Host Adapter supports legacy (non-Ultra2) peripheral
devices. However, we recommend that you attach only Ultra2 LVD devices to the
Adapter. This is because, if you do attach any other type of SCSI device, the bus will
become limited to (a) the speed of the slowest device and (b) the length supported
by the least distance-tolerant device.
3.6 The Complete Package
Your complete Ultra2 LVD SCSI Host Adapter package includes the following:
• The Adapter card itself.
• A 125-cm (4.1-ft.) 68-pin internal “Wide SCSI” ribbon cable.
• Two diskettes containing driver software.
• This manual.
If anything is missing, contact Black Box right away. If the package has been
damaged, contact both Black Box and the shipping carrier.

CHAPTER 4: Installation and Configuration
4. Installation and Configuration
This chapter describes how to install and configure your Ultra2 LVD SCSI Host
Adapter. (If you are installing multiple Adapters in a clustered system, refer to
Section 4.5.) If you have any difficulty, please refer to Section 6.1.
4.1 Installing the Adapter Itself
Follow these instructions to install your Ultra2 LVD SCSI Host Adapter:
NOTE
If you’re running Windows NT on the computer you’ll be installing the
Adapter in, you might want to install the driver before you install
hardware. If so, follow the procedure listed in Section 5.4.
1. Turn OFF your computer, unplug it, and disconnect it from all other devices.
2. Take precautions to keep from damaging the Adapter with any accidental
static discharge. At the very least, discharge yourself on a metal part of the PC
chassis or on some other metallic surface before touching the Adapter. If
possible, stand on an anti-static mat and wear a grounding strap or anti-static
gloves.
3. (Optional) If you need to hardwire termination on the Adapter so that it’s
always enabled (ON), install the necessary jumper(s) on the Adapter if you
haven’t done so already. See Section 3.4.
4. Remove the cover from the computer case.
5. Locate an unused 32-bit PCI expansion slot (the slot must support
busmastered data transfers). PCI slots are shorter than ISA or EISA slots and
are typically white. Usually there are several of them on the motherboard.
(One of these might be a shared slot into which you can insert either an
ISA/EISA board or a PCI board.) Refer to your PC’s documentation if you’re
still not sure which ones are the PCI slots.
Once you’ve located a PCI slot, unscrew and remove the metal bracket
that covers the card-slot opening. (Save the screw; you will be using it to
secure the host adapter in your computer.)
21
ULTRA2 LVD SCSI HOST ADAPTER
6. Holding the SCSI Host Adapter by the mounting bracket and card edge, with
it oriented so that the external connectors are facing the right way, insert the
Adapter in the PCI slot. Press it down firmly so the contacts are securely
seated in the slot. See Figure 4-1 on the next page.
CAUTION!
Though the PCI connector is keyed to prevent cards like the Adapter
from being inserted incorrectly, it is possible to damage the Adapter by
forcing it into other types of connectors.
Figure 4-1. Inserting the Adapter in a PCI slot.
7. When the Adapter is firmly seated, secure its metal bracket to the PC’s chassis
with the screw you removed in step 3.
8. (Optional) Most computers have one or more hard-drive-activity LEDs on
their front panel. If you want to, you can use your own cabling (because we do
not include cables for this purpose) to attach one of these indicators to the
Adapter’s four-pin LED connector, J3 (see Figure 3-2 on page 19 and
Figure 4-2 on the next page). Once you do so, the LED will light whenever
there is activity involving the attached Adapter anywhere on the SCSI bus.

9. Most PCI-bus computers will automatically assign the Adapter an I/O address,
IRQ channel, and BIOS address. If this is not the case with your system, you’ll
have to do this manually, either by setting jumpers on the PC’s motherboard
(which you can do now; refer to your PC’s documentation) or changing the
settings of the PC’s CMOS BIOS (you’ll have to do this later—see
Section 4.3). (If the PC will be booting from a SCSI drive attached to the
Adapter, you might also need to change the drive-type setting in the PC’s
BIOS, because it might be expecting the boot drive to be an IDE drive.)
10. If you are attaching any internal SCSI devices to the Adapter, go on to
Section 4.2. Otherwise, replace the PC’s cover, reconnect all devices,
plug the PC back in, and go on to Section 4.3.
23
ULTRA2 LVD SCSI HOST ADAPTER
4.2 Attaching Other SCSI Devices to the Adapter’s Bus
You can connect as many as fifteen internal and external SCSI devices to your
Ultra2 LVD SCSI Host Adapter. Follow the directions listed in this section. (If you
are connecting SCSI devices to multiple Adapters to form a clustered system, refer
to Section 4.5.)
4.2.1 CONNECTING INTERNAL SCSI DEVICES
If you are connecting internal SCSI devices, make sure to use a SCSI ribbon cable
that (a) is not too long (see Section 3.3), (b) has the appropriate characteristics
(see Section 3.3), and (c) has enough connectors to accommodate the Adapter
and all of your internal peripherals. Figure 4-3 below shows the preterminated
Wide (68-pin) internal cable that comes with the Adapter; it has enough
connectors for four internal SCSI devices.

Figure 4-3. The Adapter’s included internal ribbon cable.
This cable is 125 cm (4.1 ft.) long; whether you use it or some other cable, keep
in mind that the total length of cable on the Adapter’s SCSI bus, including both
internal and external cables, mustn’t exceed 12 m (39.4 ft.) unless you’re attaching
one and only one peripheral, in which case you can run as far as 25 m (82 ft.). And
this assumes that all of your devices are Ultra2 SCSI LVD compliant; if you are
attaching any legacy devices, the maximum total bus length will be much less:
• 6 m (19.7 ft.) if the only legacy devices attached to the bus are SCSI-1 or Fast
SCSI (SCSI-2) devices.
• 3 m (9.8 ft.) if you have four or fewer devices attached to the bus and any of
them are Ultra SCSI (SCSI-3) devices.
• 1.5 m (4.9 ft.) if you have five or more devices attached to the bus and any of
them are Ultra SCSI (SCSI-3) devices.
The cable should have an impedance of at least 120±8 ohms if any Ultra2 SCSI
LVD devices are attached; the impedance can be as low as 90±8 ohms only if all
attached devices are non-Ultra2-type.
24
CHAPTER 4: Installation and Configuration
Take these steps to connect internal SCSI devices to the Adapter:
1. If you haven’t already done so, turn OFF and unplug the PC, disconnect all
other devices from it, and remove its cover.
2. If you haven’t already done so, prepare each internal SCSI peripheral for
installation: configure the device’s SCSI ID and termination. (If you’ll be using
the included cable, or some other preterminated cable, all of the devices
should have termination turned OFF. If you’ll be using a non-terminated
cable, turn the last device’s termination ON and leave the others OFF.) For
instructions, see the device’s documentation as well as Sections 3.2 and 3.3.
3. Install each internal SCSI peripheral in your computer. Refer to your
computer’s and peripherals’ documentation for instructions.
4. Plug one end of your internal SCSI cable into the Adapter’s appropriate
internal SCSI connector. (If you’re using the cable included with the Adapter,
plug in the unterminated end.) Make sure the colored stripe that runs the
length of one edge of the cable is aligned with Pin 1 of the Adapter’s
connector. The cable should be keyed for proper insertion. Figure 4-4 below
shows how to plug in this cable.
SCSI Ribbon Cable
Internal Connector
(68-Pin Micro D68)
Figure 4-4. Plugging a narrow internal cable into the Adapter.
5. Plug the internal cable’s other connectors into the internal SCSI peripherals
that you installed in step 3. (If you are using the cable included with the
adapter, or some other cable with 68-pin connectors, and any of the
peripherals are Narrow [50-pin] devices, you will need to attach 50-pinfemale-to-68-pin-female adapters, such as our product code EVNSCT38,
between the cable and the device.) Also attach internal power cables to any of
these devices that get their power from the PC. Refer to the instructions for
doing these things in the peripherals’ documentation. Remember to
terminate the last internal device.
25
ULTRA2 LVD SCSI HOST ADAPTER
6. Inspect your internal cabling one last time to make sure it is attached
correctly everywhere, then replace the PC’s cover. If you are attaching any
external SCSI devices to the Adapter, go on to Section 4.2.2; otherwise,
reconnect all external devices to the PC and plug the PC back in.
4.2.2 CONNECTING EXTERNAL SCSI DEVICES
If you are connecting external SCSI devices, make sure that (a) you have enough
external SCSI cables to accomodate all of your devices (the Adapter does not come
with any external cables), (b) the total length of the cables is not too great, and
(c) the cables have the appropriate characteristics (see Sections 3.3 and 4.2.1).
If your external devices have micro D68 connectors like the Adapter itself does,
you can use our External Ultra2 LVD SCSI Cable (product code EVMS25).
1. Prepare each external SCSI peripheral for installation: configure the device’s
SCSI ID and termination (terminate the last external device attached to the
bus). For instructions, see the device’s documentation as well as Sections 3.2
through 3.4.
2. Plug the connector at one end of the first external SCSI cable into the
Adapter’s external SCSI connector. These connectors will be keyed for proper
cable insertion.
3. Plug the connector at the other end of the external SCSI cable into one of
the SCSI connectors on the first external SCSI peripheral, following the
instructions for doing this in the peripheral’s documentation.
4. To connect other external SCSI devices, use additional external SCSI cables
to daisychain each device to the previous device until all external SCSI devices
have been connected, as described in the peripherals’ documentation and as
shown in Figure 4-5 on the next page (refer to the peripherals’ documentation
for more information). Remember to terminate the last external device.
5. Reconnect all external devices to the PC and plug the PC back in.
26
CHAPTER 4: Installation and Configuration
Figure 4-5. An external SCSI daisychain.
4.3 Initial Startup
Once you’ve installed your Ultra2 LVD SCSI Host Adapter and its associated
devices, power up its host computer system and all external devices. Interrupt the
normal bootup process at this point if you need to change the settings of the PC’s
CMOS BIOS in order to assign the Adapter an I/O address, IRQ channel, and/or
BIOS address, or if you need to change the drive-type setting for the boot disk (see
step 9 in Section 4.1; if you need to do this, reboot when you’re finished). During
the boot process, watch for these things to be displayed (although this list might
vary depending on the design of your system’s BIOS):
• The normal power-on self-test and memory test.
• A sign-on message from the Adapter, followed by a list of attached SCSI
peripheral devices.
Make sure that the self-test and memory test look okay, and make sure that
the Adapter’s list of attached devices is correct. If everything checks out, your
computer system should be ready for initial configuration (including, as is
necessary in some situations, low-level hard-disk formatting to initialize drives);
go on to Section 4.4, then Section 4.6.
27
ULTRA2 LVD SCSI HOST ADAPTER
4.4.1 WHY YOU NEED TO DO THIS
A new SCSI disk drive is normally low-level formatted at the factory to simplify
installation. Every SCSI hard-disk drive must be physically low-level formatted,
partitioned, and logically formatted before it can be used to store data. SCSI hard
disks are physically low-level formatted at the factory and do not usually need to be
formatted again. (If you do need to low-level format a disk, see Section 4.4.2.)
Howevere, if you connect a new SCSI hard-disk drive to your Ultra2 LVD SCSI
Host Adapter, you must partition and logically format the drive. For DOS,
Windows 3.x***?, Windows 95, and Windows 98, use the DOS commands FDISK
and FORMAT to do this (refer to the documentation for your PC, your hard drive,
DOS, and—if necessary—Windows). For other operating systems, refer to the
operating system’s documentation for instructions.
If you are booting from a SCSI hard-disk drive, make sure the “Hard Disk” or
“Hard Drives” setting in your PC’s CMOS program is set to “None” or “No Drives
Installed,” as is required for SCSI hard drives. See your PC’s documentation for
details.
If you’ve installed both SCSI and non-SCSI (IDE, for example) disk drives, the
non-SCSI drive is typically the boot drive. But if your computer supports the BBS
(BIOS Boot Specification), not only can both SCSI and non-SCSI drives coexist,
you can specify which drive to boot from. See your PC’s documentation for more
details.
4.4.2 LOW-LEVEL FORMATTING
A low-level format will erase any data that is stored on the target disk. Before
attempting to perform a low-level format, make sure the data on the target disk has
been backed up. You can do a low-level format with the Ultra2 LVD SCSI Host
Adapter’s SmartSCSI Setup Utility; see Section 4.6.6.
The low-level format sets the media to a state which is easily recognized by the
host adapter on the SCSI bus. Once this format is completed, you will need to
partition the drive. Refer to your operating system’s documentation for further
information on partitioning drives.
28
CHAPTER 4: Installation and Configuration
4.5 Multiple Initiators and Clustering
A multiple-initiator environment is one in which the SCSI bus has two or more host
adapters. To work in a cluster, the host adapters must perform properly in such an
environment—by not resetting the bus without an explicit host command, for
example. Our Ultra2 LVD SCSI Host Adapters are built for multi-initiator
operation and adhere strictly to the SCSI standard.
Figure 4-6 on the next page illustrates the principal components in a cluster’s
I/O system. It shows a simple cluster with two servers sharing access to online
storage (the basic model for Microsoft’s MSCS clusters). Both servers contain an
host adapter that provides access to the shared extemal I/O bus. Servers can share
disks or arrays attached to this bus. The operating system controls contention for
disk access by either resolving access conflicts with a component called a
distributed lock manager (DLM) or using a so-called “shared-nothing” model that
partitions disks and arrays, giving each server control over a subset of the storage
under normal circumstances. MSCS uses the shared-nothing approach.
In such applications, multiple initiators can be used on a single SCSI bus. The
bus is configured to have more than one host adapter inserted into at least two
distinctly different computer systems sharing peripheral devices. In these
circumstances, it is possible to have one of the two computer systems turned off.
Under these conditions, the host adapter has a jumper that can be enabled
(closed) to set the active on-board termination ON all the time, regardless of
whether power is applied or not (refer to Section 3.4). The host adapter is shipped
without the jumper installed, and this setting need not be changed in most cases.
Before operating such a system, visually inspect the configuration you have
installed to verify that all cables have been inserted correctly.

4.6 The Setup Utility
4.6.1 THE BOOT OPTIONS, SELECT CHANNEL MENU, AND MAIN MENU
Among the Ultra2 LVD SCSI Host Adapter’s built-in firmware programs is a menudriven SCSI Setup Utility, with which you can change the Adapter’s settings without
opening the computer or handling the Adapter’s circuit board. (Note that the
Adapter’s default settings are appropriate for most PCI systems, so odds are you
won’t need to run the Utility.) To start the Utility, first make sure that all of the
devices attached to the SCSI bus are powered up when the host computer system is
turned ON. Then reboot the PC the Adapter is installed in and wait for this
prompt to appear (it will be preceded by version and copyright info):
!!! Press < Ctrl > < I > for SmartSCSI Setup Utility !!!
!!! Press < Ctrl > < B > to boot from SCSI CD-ROM !!!
!!! Press < ESC > to continue !!!
30
CHAPTER 4: Installation and Configuration
When you see this prompt, you can either:
• Wait five seconds or press [ESC] to continue with the boot process;
• Press [CTRL] [B] to boot from a SCSI CD-ROM attached to the Adapter
(if this capability has been firmware-enabled—see Section 4.6.5); or
• Press [CTRL] [I] to start the Utility.
The Utility’s Main Menu (shown, with Device Setup selected, in Figure 4-7
below) appears directly as soon as you run the Utility. When it does, you will
have five main options to choose from:
Scan Bus
Device Setup
Adapter Setup
Utility
BIOS Setup
Disk
Selecting any of these options (using the right- and left-arrow keys) will cause the
Utility to display a corresponding submenu; see Sections 4.6.2 through 4.6.6
respectively. You can also exit the utility at any time by pressing <ESC> (Escape);
see Section 4.6.7.

ULTRA2 LVD SCSI HOST ADAPTER
4.6.2 THE SCAN BUS SCREEN
If you select “Scan Bus” at the Main Menu and press ENTER, the Utility scans the
SCSI bus and displays a screen that lists, in the order of their SCSI IDs, the devices
it has found, as well as the IDs without any devices assigned to them. While you’re
at this screen, you can press <ENTER> to “Execute” a new scan (to rescan the bus).
Keep in mind that (a) the best ID for a bootable hard disk is ID 0, and
(b) otherwise, you should only change a device’s ID if it conflicts with the ID of
another device on the same bus (refer to the device’s documentation for how to do
this).
4.6.3 THE DEVICE SETUP MENU
If you select “Device Setup” at the Main Menu and press ENTER, the Utility displays a
screen listing all of the bus’s possible SCSI IDs and a set of attributes that you can set
for those IDs. Use the right-, left-, up-, and down-arrow keys to select any attribute,
the plus and minus keys to change the setting of the selected attribute, or <F8> to
reload the factory defaults for all attributes.
Asynchronous Transfer: Set this value to “Yes” or “No” (the factory-default
setting is “No”) to respectively enable or disable asynchronous data transfer for the
corresponding ID. The maximum data rate at which the Ultra2 LVD SCSI Host
Adapter will transfer data asynchronously is 10 MB/second.
Maximum Synchronous Transfer Rate: Set this value to the maximum sync data
rate at which the correpsonding devices can operate. (You can press “+” and “–” to
cycle through the possible settings.) Your Adapter will run at 80 MB/second; this is
the factory-default setting for all SCSI IDs. Whenever you connect a new SCSI
device to the Adapter’s bus, refer to the device’s manual to determine its actual
maximum data rate. If you still can’t figure it out, set this value to 10.0
(10 MB/second) until you can contact the device’s manufacturer.
DOS Space > 1 GB: This value has to do with how information stored on SCSI
hard drives is accessed. (It has no meaning for non-hard-drive devices.) Under the
“No” setting, the Adapter assumes that the corresponding drive has a maximum of
64 read/write heads and 32 sectors, a “head-mapping” configuration that conforms
to the normal MS-DOS limit of 1024 cylinders (one gigabyte of capacity). Under
the factory-default “Yes” setting, the Adapter assumes that the drive has a
maximum of 255 heads and 63 sectors, an 8032-cylinder head-mapping
configuration that corresponds to almost 8 GB of DOS-accessible capacity.
32
CHAPTER 4: Installation and Configuration
CAUTION!
If any hard drive connected to the Adapter already has data stored on it,
changing the head mapping will corrupt or erase that data and could
cause other unexpected problems. If you want to keep the data on a
drive, please back it up before changing the “DOS Space > 1GB” setting,
then delete the target drive’s existing partitions with this Setup Utility’s
“Format” Disk Utility function or the DOS FDISK utility. Then, after you
change this setting, you can restore and reinstall from the backup.
All device drivers for the Adapter will support different head mappings based on
the setting of this option:
Under MS-DOS, OS/2, and Windows NT, we recommend the “Yes” setting for
any hard disk whose capacity is greater than 1 GB.
SCO UNIX does not have a 1-GB barrier, but it must know whether or not the
boot-file system is located within the first 1024 cylinders of disk space in order to
perform its kernel-boot routines. If your root file system is larger than 1 GB or is
located beyond the first 1 GB of disk space, you should set "Dos Space > 1GB" to
“Yes.” Otherwise, you can safely set it to “No” (although, to be on the safe side, we
recommend that you set it to “Yes” anyway).
Note that, unlike the other operating systems the Adapter supports, SCO UNIX
cannot support having drives with different head mappings attached to the same
bus (channel). The head mapping used on the drive with SCSI ID 0 must be used
on all other drives attached to the same bus.
On machines running multiple operating systems, you must use the same head
mapping for any given hard drive across operating systems. Unless one of your operating systems is SCO UNIX, however, different drives can have different head mappings.
In general, we recommend that, to be on the safe side, you set “DOS Space >
1GB” to “Yes” for any SCSI hard disk with capacity greater than 1GB.
Spin Up Disk Drive: Set this option to “Yes” to have the SCSI Host Adapter
initiate motor spin-up for SCSI disk drives. This way, the Adapter’s BIOS can
conserve system power during boot-up by signaling the attached devices to start at
delayed intervals. The factory-default setting for this option is “No.” This option
has no effect on peripherals that are not disk drives.
33
ULTRA2 LVD SCSI HOST ADAPTER
Enable Disconnect: When this option (usually referred to as “disconnect/
reconnect”) is set to “Yes” (the factory-default setting), devices can temporarily
disconnect from the SCSI bus to allow the Adapter to perform other functions on
the bus. The device and the Adapter can then reconnect when the bus is needed.
We strongly recommend that you not set this option to “No” unless the
corresponding device is an older one that cannot support disconnect/reconnect.
Enable Wide Negotiation: This option determines whether or not the Adapter
will start data-transfer negotiations with the corresponding device by requesting a
“wide SCSI” (16-bit) path. Set this option to “No” for any narrow-only device or for
any other attached device that doesn’t seem to handle wide data transfer properly
(as is often the case with certain older CD-ROM, recordable CD, and tape drives).
The factory-default setting for this option is “Yes.”
4.6.4 THE ADAPTER SETUP MENU
If you select “Adapter Setup” at the Main Menu and press ENTER, the Utility displays
a screen at which you can set three key options for the Ultra2 LVD SCSI Host Adapter
itself. Use the up- and down-arrow keys to select an option, the plus and minus keys to
change its setting, or <F8> to reload the factory-default settings for all options.
Host Adapter SCSI ID: If necessary, you can use this option to change the
Adapter’s ID number on the SCSI bus. The Adapter supports sixteen IDs
numbered 0 through 15. ID 7 (the Adapter’s factory-default ID) has the highest
boot priority (is examined first during the boot process); from there, IDs are
examined in numeric order from 0 to 15. This means that if you have to change
the Adapter’s ID, you should make it as low a number as possible.
You can have multiple SCSI host adapters attached to the same SCSI bus (see
Section 4.5); these must all have different SCSI IDs. But if you have multiple
Adapters that are each attached to separate SCSI buses, even if they’re installed on
the same PCI bus, you don’t have to use different SCSI IDs for the Adapters.
SCSI Terminator: You can use this option to have the Adapter auto-terminate
itself (“Automatic,” the factory-default setting) or—if the Adapter doesn’t seem to
autosense the bus state properly, or if for whatever reason you would rather set
termination yourself—set its termination always “ON” (if the Adapter is at the end
of the bus) or “OFF” (if the Adapter is in the middle of the bus), or set the
termination to the proper combination of “High bit ON”/“OFF” and “Low bit
ON”/“OFF” as described in Section 3.4.
34
CHAPTER 4: Installation and Configuration
SCSI Parity Check ON: You can use this option to enable or disable parity
checking on the SCSI bus by the Adapter. The default setting for this option is
“Yes”—if you leave it set this way, make sure that all of your peripherals on which
parity checking can be user-enabled or -disabled have it enabled. If any of the
devices attached to the bus don’t support parity checking, set this option to “No.”
4.6.5 THE BIOS SETUP MENU
If you select “BIOS Setup” at the Main Menu and press ENTER, the Utility displays
a screen at which you can set four key options for the Ultra2 LVD SCSI Host
Adapter’s BIOS. Again, use the up- and down-arrow keys to select an option, the plus
and minus keys to change its setting, or <F8> to reload the factory-default settings for
all options.
Enable Host Adapter BIOS: Use this option to control whether the Adapter uses
the SCSI-disk I/O routines in its BIOS. The factory-default setting for this option is
“Yes.” If you set it to “No,” you will disable the Adapter’s ability to use the boot
capabilities and other features of its BIOS, including all of the other features normally
available in this menu (they will be “grayed out”). Only disable the BIOS if you want to
use other drivers for all of the attached devices.
Boot Device ID: You can use this option to select which SCSI device will be the
designated boot device for the system. The factory-default device ID is “0”, which is
the best choice for most operating systems and applications.
BIOS Support for Bootable CD-ROM: When this option is set to “Yes,” the
Adapter will support booting from one CD-ROM (and only one CD-ROM at any
given time). (This option is useful if you need to install an operating system or
other software from CD-ROM at boot-up.) The default setting for this option is
“No.” Unless this option is set to “Yes,” pressing [CTRL] [B] at boot time to boot
from CD-ROM (see Section 3.2.1) will have no effect.
BIOS Treat Removable Disk as Fixed Disk: When this option is set to “Yes,” the
Adapter’s BIOS will treat removable disks as if they were fixed disks, so you can run
removable-disk media without needing additional (third-party) software drivers.
(You will still need third-party drivers, however, if you need to be able to hot-swap
removable disks while the system is operating. Hot-swapping removable disks
without using drivers that support this function will reult in lost data and possibly
other unexpected problems.) The default setting for this option is “No.”

ULTRA2 LVD SCSI HOST ADAPTER
4.6.6 THE DISK UTILITY MENU
If you select “Disk Utility” at the Main Menu and press ENTER, the Utility displays
a screen much like the Scan Bus screen (see Section 4.6.2) that lists the devices on
the SCSI bus. Use the up- and down-arrow keys to select a device; if you highlight a
SCSI hard drive and press ENTER, a small window showing the “Format Disk” and
“Verify Disk” options is superimposed on the screen.
Format Disk: Use this option to perform a low-level disk format on the target
disk drive. (Be aware that this will erase all the data resident on the drive; make
sure to back up any data you want to keep!)
A new SCSI disk drive is normally low-level-formatted at the factory before it is
shipped in order to simplify installation. Usually you can use new SCSI drives right
out of the box, as soon as you partition them (refer to your operating system’s
documentation for how to do this), without having to do a low-level format.
Drives that have been previously used with other SCSI adapters, on the other
hand, should be low-level-formatted before you use them with your new Ultra2
LVD SCSI Host Adapter; this will prevent any operating or reliability problems that
might otherwise arise as a result of incompatibilities between the different
Adapters. The low-level format will erase the target drive and reset it to a state
which is easily recognized by the Adapter across the SCSI bus. Once this format is
complete, you will need to partition the drive.
For more information about hard-disk preparation, see Section 4.4.
Verify Disk: This option will test the integrity of the recording medium of a
properly formatted drive and determine whether or not the drive is functioning
properly. During the test process, any bad sectors on the disk will be identified and
flagged so that the computer doesn’t try to write to or read from them. If a bad
sector is found, you will be offered two options for what to do about it: “Reassign”
(mask the flagged bad sector and reassign its sector number to a good sector in
one of the reserved “replacement” areas on the disk) or “Skip” (do not reassign the
number of the flagged sector).
4.6.7 EXITING THE UTILITY
To exit the Setup Utility, press <ESC> (esacape) at any time. and select “Yes” when
you are asked to confirm that you want to exit. Any changes you might have made
with the Setup Utility will be saved in the Ultra2 LVD SCSI Host Adapter’s NVRAM
as soon as you make them, but will not take effect until you reboot the computer.

CHAPTER 5: Driver Installation
5. Driver Installation
This chapter describes how to install the necessary Ultra2 LVD SCSI Host Adapter
driver(s) for each of the operating systems that the Adapter supports. As you read
these instructions, please keep in mind that any text enclosed by <angle brackets>
is actually the name of a keyboard key: For example, if you are instructed to type
“<ENTER>”, that means you should press the ENTER key on your PC keyboard.
Similarly, <ESC> stands for the ESC (Escape) key, <CTRL> for the CTRL (Control)
key, <ALT> for the ALT (Alternate) key, and <DEL> for the DEL (Delete) key.
5.1 Installing Drivers for MS-DOS
CAUTION!
The Adapter can be used, in a limited way, in PCs running
Windows 3.1x: Once you boot into DOS and use the procedure in
Section 5.1.1 to install the MS-DOS drivers on your system, they will
enable your Windows 3.1x machine to control hard drives and CD-ROM
drives. However, Adapters installed in Windows 3.1x PCs can’t support
any other types of SCSI devices, so we strongly recommend that you
upgrade your operating system rather than operate the Adapter in a
Windows 3.1x PC.
The Ultra2 LVD SCSI Host Adapter’s ASPI driver will support extended SCSI
command functions for MS-DOS 3.30 or later. The on-board BIOS initialized
during the power-up boot routine only supports MS-DOS hard-disk operation. If
you use CD-ROM and/or MO disks, you’ll need to install the Adapter’s CD-ROM
and/or MO drivers as well as its ASPI driver. If you use other types of SCSI
peripherals, such as tape drives, you will need to install a third-party driver as well
as the ASPI driver.
The installation procedure guides you through the installation of the DOS ASPI
driver. The installation procedure described here requires some experience in
MS-DOS system setup and administration. The device driver is transferred from
Driver Disk 1 to the hard drive, from which it is automatically loaded during the
system boot routine.
37
ULTRA2 LVD SCSI HOST ADAPTER
5.1.1 INSTALLING THE ASPI DRIVER IN AN EXISTING MS-DOS SYSTEM
The ASPI driver is on Driver Disk 1. It is important that the SCSI hardware and the
operating system are installed correctly before proceeding further. If you need
help installing the MS-DOS operating system, please refer to the MS-DOS manual
before proceeding.
1. Turn on the host system and boot into MS-DOS.
2. Insert Driver Disk 1 in your floppy drive.
3. At the MS-DOS prompt, change to your active floppy drive: Assuming the
floppy drive is drive A:, type “A: <ENTER>”.
4. Type “DOSSETUP <ENTER>”.
5. A series of screens will guide you through the installation of the ASPI device
drivers. The first screen sets the installation drive and directory that the ASPI
driver will be installed on. Follow the on-screen directions and/or options to
continue the installation.
6. To activate the device driver, reboot the system by selecting the “Reboot Now”
option at the end of the installation process.
5.1.2 COMMAND-LINE OPTIONS FOR THE ASPI DEVICE DRIVER
The Ultra2 LVD SCSI Host Adapter’s ASPI device driver supports command-line
switches to optimize driver operation. Device drivers normally require no additonal
information to work effectively, but for your system or applications you might need
to turn certain features ON or OFF. In the CONFIG.SYS file, use the following
standard command format to modify the device driver’s switches:
DEVICE = C:\INIASPI\ASPIA100.SYS [driver-config option]
The “driver-config options” are:
/D
Verbose Mode provides detailed information about the driver on the
system command line when the driver is initialized.
/L
The driver scans eight LUNs (logical unit numbers) for each SCSI
target.
/Bb,dd
Scan device only on PCI BUS #b, PCI DEVICE #dd
The range for “b” is from 0 to 7 decimal.
The range for “dd” is from 0 to 20 decimal.
/Bb
Scan all the devices on PCI BUS #b
The range for “b” is from 0 to 7 decimal.
38
CHAPTER 5: Driver Installation
/Sdd Scan device only on PCI BUS #0 and device #dd
The range for “dd” is from 0 to 20 decimal.
/CCBSx
Defines the maximum number of concurrent I/O operations that
driver supports.
The range for “x” is from 1 to 16 decimal.
5.1.3 THE ASPI CD-ROM DRIVER AND ITS COMMAND-LINE OPTIONS
INICD.SYS is a DOS device driver for SCSI CD-ROM drives. It functions as the
interface between these drives and the generic Microsoft CD-ROM driver,
MSCDEX.EXE. INICD.SYS requires that the Ultra2 LVD SCSI Host Adapter’s ASPI
Manager be loaded. A “DEVICE=” or “DEVICEHIGH=” command line to load
INICD.S'YS is automatically added to the CONFIG.SYS startup file by the
DOSSETUP or SETUP program. (You will be asked whether or not you want to
load this driver high; the program will add the correpsonding command to
CONFIG.SYS depending on how you answer.) INICD.SYS is on Driver Disk 1. It has
three command-line options—/D:, /T, and /X:—as described below.
/D: or /d:—Use this option to define a “device name” for a CD-ROM drive. This
device name must also be passed to MSCDEX.EXE on its command line (using the
same /D: or/d: option). The name specified must be eight characters or fewer in
length. Valid characters are uppercase letters “A” through “Z,” lowercase letters “a”
through “z,” the digits “0” through “9,” and the underscore character. The name
must start with a letter. Examples of valid command-line phrases:
• /D:INICD001
• /d:mscd001
• /d:MYCD_01
/T or /t—Use this option to specify a timeout value to be used when sending
commands to a CD-ROM drive. If a CD-ROM drive does not respond to a
command within the specified timeout period, the command will be aborted and
an appropriate error message will be displayed. The timeout value is specified in
minutes. Valid values are “1” (one minute) through “9” (nine minutes) and “D” or
“d” (timeout disabled). We do not recommend disabling the timeout—if you do,
faulty hardware will be able to lock up your system. Examples of valid commandline phrases:
• /T4
• /Td
• /TD
• /T1
39
ULTRA2 LVD SCSI HOST ADAPTER
/X: or /x:—Use this option to exclude particular CD-ROM drives from having their
I/O handled by INICD.SYS. Excluded CD-ROM drives are identified by specifying
the host adapter, target ID, and LUN (logical unit number). These values are
separated by a colon. Groups of CD-ROM drives can also be identified. Examples
of the different ways CD-ROM drives can be excluded:
• /X0:1:2
This will exclude the drive on SCSI Host Adapter 0 (that is, the
Adapter on the PCI bus that the motherboard has designated
number zero) whose target ID is 1 and whose LUN is 2.
• /X0:2
This will exclude the drives on SCSI Host Adapter 0 whose target
ID is 2, no matter what LUN they have.
• /X0
This will exclude all of the drives on SCSI Host Adapter 0.
When DOSSETUP installs INICD.SYS, it will add command lines like those shown
below to your CONFIG.SYS and AUTOEXEC.BAT files. (These examples assume
that the Adapter drivers have been installed in the “C:\INIASPI” directory. The
device name must be exactly the same in both the CONFIG.SYS and
AUTOEXEC.BAT entries.)
CONFIG.SYS:
DEVICEHIGH=C:\INIASPI\ASPIA100.SYS
DEVICEHIGH=C:\INIASPI\INICD.SYS /D:INICD001
The first line loads the ASPI Manager and the second line loads the CD-ROM driver,
specifying the device name “INICD001” for the CD-ROM drive.
AUTOEXEC.BAT:
C :\INIASPI\MSCDEX /D:INICD001
This line loads the Microsoft supplied MSCDEX.EXE driver, instructing it to attach to the
CD-ROM drive “INICD001.” SETUP copies MSCDEX to the INIASPI directory during
installation.
40
CHAPTER 5: Driver Installation
5.1.4 THE ASPI REMOVABLE-DISK DRIVER AND ITS COMMAND LINE OPTIONS
INIDISK.SYS is a DOS “block” device driver for supporting SCSI fixed disks,
removable disks, and MO (magneto-optical) devices. INIDISK.SYS requires that the
Ultra2 LVD SCSI Host Adapter’s ASPI Manager be loaded. A “DEVICE=” or
“DEVICEHIGH=” command line to load INIDISK.S'YS is automatically added to
the CONFIG.SYS startup file by the DOSSETUP program. (You will be asked
whether or not you want to load this driver high; the program will add the
correpsonding command to CONFIG.SYS depending on how you answer.)
INIDISK.SYS is on Driver Disk 1. It has three command-line options—/R, /T, and
/X:—as described below.
/R or /r—This option specifies the number of logical drives to reserve for MO and
removable-disk devices. MO and removable-disk media are capable of being
partitioned just like a fixed disk. For every DOS partition on the medium, a logical
DOS drive letter needs to be available. INIDISK.SYS will support as many logical
drives as required (up to the maximum supported by DOS), based on the
partitioning of the medium that is present when your system boots. However, the
medium may be removed at any time and a new disk may be inserted. The new disk
may have more (or fewer) partitions then the original disk.
Use this option to reserve drive letters at startup in order to make it possible to
swap in a disk with more partitions than the original disk present at boot time had.
The value after the /R or /r determines how many drive letters will be reserved per
device. For example, if the user specifies /R4 and there are two devices attached to
the SCSI bus, then a total of eight drive letters will be reserved.
/T or /t—Use this option to specify a timeout value to be used when sending
commands to a SCSI drive. If a SCSI drive does not respond to a command within
the specified timeout period, the command will be aborted and an appropriate
error message will be displayed. The timeout value is specified in minutes. Valid
values are “1” (one minute) through “9” (nine minutes) and “D” or “d” (timeout
disabled). We do not recommend disabling the timeout—if you do, faulty
hardware will be able to lock up your system. Examples of valid command-line
phrases:
• /T4
• /Td
• /TD
• /T1
41
ULTRA2 LVD SCSI HOST ADAPTER
/X: or /x:—Use this option to exclude particular SCSI drives from having their
I/O handled by INIDISK.SYS. Excluded SCSI drives are identified by specifying the
host adapter, target ID, and LUN (logical unit number). These values are
separated by a colon. Groups of SCSI drives can also be identified. Examples of the
different ways CD-ROM drives can be excluded:
• /X0:1:2
This will exclude the drive on SCSI Host Adapter 0 (that is, the
Adapter on the PCI bus that the motherboard has designated
number zero) whose target ID is 1 and whose LUN is 2.
• /X0:2
This will exclude the drives on SCSI Host Adapter 0 whose target
ID is 2, no matter what LUN they have.
• /X0
This will exclude all of the drives on SCSI Host Adapter 0.
When DOSSETUP installs INIDISK.SYS, it will add command lines like those
shown below to your CONFIG.SYS file. (These examples assume that the Adapter
drivers have been installed in the “C:\INIASPI” directory.)
CONFIG.SYS:
DEVICEHIGH=C:\INIASPI\ASPIA100.SYS
DEVICEHIGH=C:INIASPI\INIDISK.SYS /R2
The first line loads the ASPI Manager and the second line loads the SCSI disk driver,
specifying that a minimum of two drive letters be reserved for each MO and removable
disk attached to the SCSI bus.
42
CHAPTER 5: Driver Installation
5.1.5 THE ASPI PARTITION & FORMAT UTILITY
INIFDISK.EXE is a DOS ASPI partition-and-format utility. It requires the
ASPIA100.SYS and INIDISK.SYS drivers to be loaded in order for it to function
properly. INIFDISK.EXE is installed by the DOSSETUP program. It can partition
and format any SCSI storage device that is not being controlled by the BIOS; this
includes SCSI hard disks, magneto-optical drives, and removable-media devices.
When you run INIFDISK, its initial screen will have two windows. The top
window will list all of the SCSI devices installed in the system; you can use the upand down-arrow keys to highlight a particular device. The bottom window will
display information about the device that is currently highlighted in the top
window.
Once you select a storage device, INIFDISK will display a second two-part screen.
Its top window will list all of the device’s logical drives or volumes, physical
partitions, etc. Before you can erase existing physical partitions on a device, you
have to remove all of their logical divisions; when you select a device element
(drive, volume, partition, etc.), the bottom window will show the commands for
everything it is currently possible to do with that element, and will explain why
certain things are not yet possible to do.

ULTRA2 LVD SCSI HOST ADAPTER
5.2 Installing Drivers for Windows 95
NOTE
The procedure for installing drivers in Windows 98 is not the same as
the procedure used for Windows 95. If you are running Windows 98,
skip to Section 5.3.
With an additional software driver, your Ultra2 LVD SCSI Host Adapter will support
Microsoft Windows 95 and Windows 95b (OSR2). The installation procedure
described here requires some experience in Windows 95 system setup and
administration. The device driver is transferred from Driver Disk 1 to the hard
drive, from which it is automatically loaded during the system-boot routine.
These installation files are in the “A:\WIN95” directory on Driver Disk 1:
“A:\WIN95\INIA100.MPD” is the Adapter’s Windows 95 miniport driver, and
“A:\WIN95\INIA100.INF” is the Windows 95 installation-information file.
The Adapter’s Windows 95 driver is loaded during the system-boot routine and
will remain resident on the drive. This is accomplished by following one of the six
installation procedures listed in this section. There are three procedures for each
of the two major versions of Windows 95 (95/95a and 95b): new Windows 95
installation, adding the Adapter’s Windows 95 device driver to an existing
Windows 95 system, or updating the INIA100.MPD device driver.
NOTE
For users who are adding or updating the driver in an existing system:
To determine which version of Windows 95 you have, check the dates of
the files in your WINDOWS directory. If most of the files are dated
07/11/95, your Windows 95 is the first-release version. If they’re dated
12/31/95, you have Windows 95a or Windows 95 with Service Pak 1. If
they’re dated 08/24/96, you have Windows 95b or OSR2.
These procedures differ significantly from one another. We strongly suggest that
you carefully read the instructions for the procedure you plan to use and make
sure you understand them before proceeding with the corresponding systemconfiguration changes.
44
CHAPTER 5: Driver Installation

CHAPTER 5: Driver Installation
5.3 Installing Drivers for Windows 98
With an additional software driver, your Ultra2 LVD SCSI Host Adapter will support
Microsoft Windows 98. The installation procedure described here requires some
experience in Windows 98 system setup and administration. The device driver is
transferred from Driver Disk 1 to the hard drive, from which it is automatically
loaded during the system-boot routine.
These installation files are in the “A:\WIN95” directory on Driver Disk 1, because
they are identical to the files used for Windows 95: “A:\WIN95\INIA100.MPD” is the
Adapter’s Windows 95/98 miniport driver, and “A:\WIN95\INIA100.INF” is the
Windows 95/98 installation-information file.
The Adapter’s Windows 98 driver is loaded during the system-boot routine and
will remain resident on the drive. This is accomplished by following one of the
three installation procedures listed in this section: new Windows 98 installation,
adding the Adapter’s Windows 98 device driver to an existing Windows 98 system,
or updating the INIA100.MPD device driver. These procedures differ significantly
from one another. We strongly suggest that you carefully read the instructions for
the procedure you plan to use and make sure you understand them before
proceeding with the corresponding system-configuration changes.
5.3.1 NEW WINDOWS 98 INSTALLATION
These instructions will guide you through the installation of the Ultra2 LVD SCSI
Host Adapter’s Windows 98 driver while installing Windows 98 itself. Windows 98
will be installed from either a CD-ROM or floppy diskettes. It is important that the
hardware have been installed successfully before proceeding further. If you are
installing from a SCSI CD-ROM drive, it is important that the Adapter’s ASPI driver
and CD-ROM driver be installed (see Section 5.1) before proceeding further.
1A. If you’re installing from CD-ROM: Access the Windows 98 CD-ROM either from
the DOS prompt, from the Microsoft Windows 3.x File Manager, or through
the “My Computer” icon on the Windows 98 desktop. Execute the
SETUP.EXE program and follow the instructions on your screen.
1B. If you’re installing from floppy diskette: Put Windows 98 Setup Disk 1 in your
floppy-disk drive and boot your system. Follow the instructions on your
screen.

CHAPTER 5: Driver Installation
5.4 Installing Drivers for Windows NT
With an additional software driver, your Ultra2 LVD SCSI Host Adapter will support
Windows NT 3.5x or 4.0. With such a software driver, the host computer can
transfer data over the SCSI bus. The Adapter’s device driver for Windows NT is
copied from Driver Disk 1 to your hard drive, from which it is automatically loaded
during the system boot routine.
The following files are used for installation and will be found on Driver Disk 1:
“INIA100.SYS” is the Adapter’s Windows NT miniport driver, “TXTSETUP.OEM”
is the script file for installing INIA100.SYS during the text-only setup phase, and
“OEMSETUP.INF” is the script file for installing INIA100.SYS during the windowed
phase.
The Adapter’s Windows NT driver will be installed on the boot drive. The driver
is loaded during the system boot routine and will remain resident on the drive.
This is accomplished by following one of the four installation procedures listed in
this section: regular new Windows NT installation, new Windows NT installation
from bootable CD, diskless new Windows NT installation, or adding or updating
the Adapter driver in an existing Windows NT system. These procedures differ
significantly from one another. We strongly suggest that you carefully read the
instructions for the procedure you plan to use and make sure you understand
them before proceeding with the corresponding system-configuration changes.
In addition, if you are installing the Adapter’s Windows NT driver before you

5.5 Installing Drivers for Novell NetWare
With additional software drivers, your Ultra2 LVD SCSI Host Adapter will support
Novell NetWare 386, v3.1x, v4.1x, or v5.0. (Note, however, that users of versions of
NetWare earlier than v5.0 must upgrade their systems with the NWPA [NetWare
Peripheral Architecture] in order to be able to use the Adapter, because there are
no .DSK drivers for it—see the README.TXT file on Driver Disk 1 for more
information.) The installation procedure described here requires some experience
in Novell system setup and administration. The device drivers are transferred from
Driver Disk 1 to the hard drive from which they are automatically loaded during
the system boot routine. The diskette contains these driver files:
\NETWARE\HAM\INIA100.HAM
HAM device driver
\NETWARE\HAM\INIA100.DDI
HAM device-driver installation file
The NetWare driver will be installed on the disk drive used for NetWare system
initialization. The driver is loaded during the system boot routine and will remain
resident on the drive. This is accomplished by following one of the two installation
procedures listed in this section: new NetWare installation, or adding the Adapter
drivers to an existing NetWare system.
These procedures differ significantly from one another. We strongly suggest that
you carefully read the instructions for the procedure you plan to use and make
sure you understand them before proceeding with the corresponding systemconfiguration changes. In addition, Driver Disk 1 contains a README.TXT file
that might contain important updated information about the procedures
described in this chapter; we recommend that you read it and use it when you
perform the driver installation.
61
ULTRA2 LVD SCSI HOST ADAPTER

CHAPTER 5: Driver Installation
5.5.4 COMMAND-LINE OPTIONS FOR THE DEVICE DRIVERS
The Ultra2 LVD SCSI Host Adapter’s device drivers support command-line switches
to optimize driver performance. Device drivers normally require no additonal
information to work effectively, but for your system or applications you might need
to turn certain features ON or OFF.
To enter command-line switches, add the following command statement to
STARTUP.NCF, where “[pathname]” is the first part of the pathname
(drive:\dir\.subdir...) where INIA100.HAM is installed:
LOAD [pathname]INIA100 [driver-config option]
The “driver-config options” are:
/V
Verbose Mode provides detailed information about the driver on the
system command line when the driver is initialized
/!V
Non-Verbose Mode (default)
/L
Driver assumes that all targets have more than one LUN (logical unit
number)
/!L
Driver assumes that all targets only have LUN 0 (default)
/T:hhhh Target-enable mask word (default: FFFF hex, scan all targets)
The range for “hhhh” is from 0000 hex (disable all targets) to
FFFF hex (scan all targets).
This is a powerful and complex option by which you can have the
driver control only certain selected devices. Each of the four hex
characters stands for four of the SCSI IDs, each of which has its own
corresponding bit for which “1” = control enabled, “0” = control
disabled. For example, if you wanted the driver to be able to control
all of the devices on the bus except a CD-ROM drive on ID 3, a tape
drive on ID 6, and scanners on IDs 9 and 10, you would enter the
command phrase “/T:F9B7”:
IDs:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Binary:
1 1 1 1 1 0 0 1 1 0 1 1 0 1 1 1
|__________| |__________| |__________| |__________|
F
9
B
7
Hex:
/B:b,dd
Scan PCI DEVICE #dd on PCI BUS #b
The range for “b” is from 0 to 7 decimal.
The range for “dd” is from 0 to 20 decimal.
65
ULTRA2 LVD SCSI HOST ADAPTER
/B:b
Scan all the devices on PCI BUS #b
The range for “b” is from 0 to 7 decimal.
/Q:q
Specifies maximum decimal number of tag commands per target
(default 4)
/!Q
No tag
/WR
Read after write, hardware-verify
/!WR
Don’t verify (default)
/R
Support removable media (default)
/!R
Will not support removable media
/D
Enable support for fixed disk drive (default)
/!D
Disable support for fixed disk drive

CHAPTER 5: Driver Installation
5.6 Installing Drivers for IBM OS/2
The OS/2 driver for your Ultra2 LVD SCSI Host Adapter will support OS/2 3.0 and
4.0. The device driver for OS/2 is copied from Driver Disk 1 to your hard drive,
from which it is automatically loaded during bootup. The files on Driver Disk 1
associated with the OS/2 driver are “\OS2\INIA100.ADD” (the driver itself) and
“\OS2\INIA100.DDP” (the script file for installing the driver).
The Adapter driver developed for OS/2 will be installed on the disk drive used
for system initialization. The driver is loaded during the system boot routine and
will remain resident on the drive. This is accomplished by following one of the two
installation procedures listed in this section: either for new OS/2 installation or for
adding the Adapter’s OS/2 device driver to an existing OS/2 system.
These procedures differ significantly from one another. We strongly suggest that
you carefully read the instructions for the procedure you plan to use and make
sure you understand them before proceeding with the corresponding systemconfiguration changes. In addition, Driver Disk 1 contains a README.TXT file
that might contain important updated information about the procedures
described in this chapter; we recommend that you read it and use it when you
perform the driver installation.

operating system can be installed from floppy diskettes or from CD-ROM. The
Adapter’s OS/2 driver is on Driver Disk 1. It is important that the Adapter
hardware has been installed successfully before proceeding further.
1. Make a backup copy of OS/2 Diskette 1 using a blank diskette and label it
something like “OS/2 Diskette 1 for SCSI Adapter”.
2. Copy the “\OS2\INIA100.ADD” file from Driver Disk 1 to the root directory on
the “OS/2 Diskette 1 for SCSI Adapter” you just made.
3. Using an appropriate text editor, modify the CONFIG.SYS file on the “OS/2
Diskette 1 for SCSI Adapter” by adding these lines for the Adapter driver at
some point after the “SET OS2_SHELL=CDINT.EXE” line:
BASEDEV=INIA100.ADD
SET COPYFROMFLOPPY=1
Once you’ve added thes lines, save the file.
4. Insert the Installation Diskette—this is another one of the operating system
diskettes—into drive A: and turn on your computer. This will begin the OS/2
installation and establish an OS/2 bootable hard drive.
5. When prompted, insert the “OS/2 Diskette 1 for SCSI Adapter”. Follow the
on-screen instructions to continue.
6. This completes the Adapter’s device-driver installation for OS/2. Follow the
on-screen instructions to finish your OS/2 installation; also refer to your
OS/2 manual for a complete description of installation procedures.

ULTRA2 LVD SCSI HOST ADAPTER
5.6.3 COMMAND-LINE OPTIONS FOR THE DEVICE DRIVER
The Ultra2 LVD SCSI Host Adapter’s device drivers support command-line switches
to optimize driver performance. Device drivers normally require no additonal
information to work effectively, but for your system or applications you might need
to turn certain features ON or OFF. In the CONFIG.SYS file, use the following
standard command format to modify the device driver’s switches:
BASEDEV = INIA100.ADD [driver-config option]
The “driver-config options” are:
/V
Verbose Mode provides detailed information about the driver on
the system command line when the driver is initialized
/!V
Non-Verbose Mode (default)
/ET
Driver assumes that all targets have more than one LUN (logical
unit number)
/!ET
Driver assumes that all targets only have LUN 0 (default)
/T:hhhh
Target-enable mask word (default: FFFF hex, scan all targets)
The range for “hhhh” is from 0000 hex (disable all targets) to
FFFF hex (scan all targets).
This is a powerful and complex option by which you can have the
driver control only certain selected devices. Each of the four hex
characters stands for four of the SCSI IDs, each of which has its own
corresponding bit for which “1” = control enabled, “0” = control
disabled. For example, if you wanted the driver to be able to
control all of the devices on the bus except a CD-ROM drive on
ID 3, a tape drive on ID 6, and scanners on IDs 9 and 10, you would
enter the command phrase “/T:F9B7”:
IDs:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Binary:
1 1 1 1 1 0 0 1 1 0 1 1 0 1 1 1
|__________| |__________| |__________| |__________|
F
9
B
7
Hex:
/B:b,dd
70
Scan PCI DEVICE #dd on PCI BUS #b
The range for “b” is from 0 to 7 decimal.
The range for “dd” is from 0 to 20 decimal.
CHAPTER 5: Driver Installation
/B:b
Scan all the devices on PCI BUS #b
The range for “b” is from 0 to 7 decimal.
/A:n
Assigns adapter number based on BIOS address
/DM:t,t,...
Enable direct-access-storage-device (DASD) manager support
The “t”s here and in the next three options stand for the SCSI
target IDs of the affected devices; these must be separated by
commas. Refer to your OS/2 documentation for more information
about the DASD manager function.
/!DM:t,t,...
Disable DASD manager support
/SM:t,t,...
Enable SCSI manager support
Refer to your OS/2 documentation for more information about
the SCSI manager function.
/!SM:t,t,...
Disable SCSI manager support
/Q:q
Specifies maximum decimal number of tag commands per target
(default 4)

5.7 Installing Drivers for Linux
Drivers have been developed for the Ultra2 LVD SCSI Host Adapter for use with
most of the major distributions of Linux. However, the procedures for installing
these drivers and recompiling the operating system vary from distribution to
distribution and change frequently. Because this is the case, the procedures for
installing these drivers aren’t included in this manual. Instead, take these steps:
NOTE
This procedure might change as our Web and ftp sites change. If you
can’t find the necessary files, please call the Conversions group of Black
Box Technical Support for assistance.
1. Go to our Web site at http://www.blackbox.com and select “Software Updates.”
This will take you to ftp://ftp.blackbox.com/pub.
2. Select the “Conversions” folder.
3. When the Conversions page is displayed, download the “linux515.zip” file; this
archive will contain driver source code along with instructions for installing and
compiling it.
72
CHAPTER 5: Driver Installation
5.8 Installing Drivers for SCO UNIX
The SCO UNIX device driver for your Ultra2 LVD SCSI Host Adapter will support
SCO UNIX System V/386 Release 3.2v4.0 or later; SCO Open Desktop v2.0, 3.0, or
later; and SCO Open Server Releases 3.0 and 5.0.x. The device drivers are
transferred from the floppy diskette to the hard drive, from which they are loaded
during system initialization. The two SCO UNIX device-driver files on Driver Disk 2
are the object file “driver.o” and the definition file “space.c”. Before proceeding,
you might want to have the following reference documentation handy in addition
to this manual:
• SCO UNIX documentation, installation and user’s guide
• The systems setup and installation guide
• The documentation for your system peripherals
• Any README.TXT file contained on Driver Disk 2. Such a file might contain
important updated information about driver-installation procedures.
The Adapter drivers developed for SCO UNIX will be installed on the disk drive
used for system initialization. The drivers are loaded during the system boot
routine and will remain resident on the drive. This is accomplished by following
one of the three installation procedures listed in this section: new SCO UNIX
installation, adding the device drivers to an existing SCO UNIX system (Adapter is
not bootable), or adding the drivers to an existing system and making the Adapter
bootable. These procedures differ significantly from one another. We strongly
suggest that you carefully read the instructions for the procedure you plan to use
and make sure you understand them before proceeding with the corresponding
system-configuration changes.
Another thing you need to check on before you go any further is the interrupt
and SCSI ID settings in your system:
• You can assign interrupt-request level (IRQ) 9, 11, or 15 to the Ultra2 LVD
SCSI Host Adapter; we recommend IRQ 11. Avoid using IRQ 10 as the
Adapter’s interrupt.
• Set the primary SCSI disk (the boot disk) to ID 0 (this is a first-time-installation
requirement)
• If you’ve attached a tape drive to the Adapter, set its target ID to 2. (Please be
aware that you will still need a third-party driver for any tape drive.)
• If you’ve attached a CD-ROM drive to the Adapter, set its target ID to 5. (Please
be aware that you will still need a third-party driver for any CD-ROM drive.)
Please refer to your system’s documentation to set the interrupt levels and to your
peripherals’ documentation for help in setting SCSI IDs.

5.8.1 INSTALLING THE DRIVER IN A NEW SCO UNIX SYSTEM
Take these steps to install the Ultra2 LVD SCSI Host Adapter driver along with your
new SCO UNIX operating system:
1. Insert the SCO UNIX N1 boot disk into the floppy drive and turn on the
system. At the SCO UNIX boot prompt, type “link <ENTER>”.
2. The system will ask you what packages you want linked to the system; type
“a10 <ENTER>”. The system at this point will boot into SCO UNIX. Please
refer to the SCO UNIX Documentation for additional information. When
prompted by the installation routine, insert Driver Disk 2 diskette in your
floppy drive and press <ENTER>.
3. Please refer to the SCO UNIX Documentation for additional information.
You have completed the installation of the Adapter driver for SCO UNIX.
5.8.2 ADDING THE DRIVER TO AN EXISTING SCO UNIX SYSTEM (ADAPTER NOT BOOTABLE)
Take these steps to install the Ultra2 LVD SCSI Host Adapter driver in an existing
SCO UNIX system without making the Adapter you just installed a bootable adapter:
1. Insert Driver Disk 2 in your floppy drive.
2. Type: “installpkg <ENTER>” at the command prompt.
3. The system will ask you what packages you wish to install. Type: “a10 <ENTER>”.
4. Type these lines to change the directory and rebuild the UNIX kernel:
cd /etc/conf/cf.d <ENTER>
. /link_unix <ENTER>
5. You have completed the link procedure for the Adapter driver. Exit and
reboot the system.
74
CHAPTER 5: Driver Installation
5.8.3 ADDING THE DRIVER TO AN EXISTING SCO UNIX SYSTEM AND MAKING THE ADAPTER
BOOTABLE
Take these steps to install the Ultra2 LVD SCSI Host Adapter driver in an existing
SCO UNIX system and make the Adapter you just installed bootable:
1. Insert Driver Disk 2 in your floppy drive.
2. Type “installpkg” at the command prompt and press <ENTER>. The system
will ask you what packages you want to install. Type: “a10<ENTER>”.
3. Edit the “mscsi” file. First type in these lines at the system prompt:
cd /etc/conf/cf.d < ENTER >
cp mscsi mscsi.bak < ENTER >
vi mscsi < ENTER >
Once you are inside vi, the editor program, you need to manually add lines to
“mscsi” that identify all of the devices attached to the Adapter. Refer to the
example below: “ha” stands for “host adapter” (for which you should enter
“a10” for each device attached to an Ultra2 LVD SCSI Host Adapter); “attach”
stands for the type of device attached (“Stp” = tape drive, “Sdsk” = hard disk
drive, “Srom” = CD-ROM drive); “number” stands for the adapter number, a.
k. a. the number that the motherboard has assigned to the PCI bus the
Adapter is on; “ID” stands for the SCSI ID number; “lun” stands for logical
unit number; and “bus” stands for bus number.

ULTRA2 LVD SCSI HOST ADAPTER
5.9 Installing Drivers for SCO UnixWare
The SCO UnixWare device driver for your Ultra2 LVD SCSI Host Adapter will
support UnixWare 2.1x. The device driver is transferred from Driver Disk 2 to the
hard drive, from which it is loaded during system initialization.
The Adapter drivers for SCO UnixWare will be installed on the disk drive used
for system initialization. The drivers are loaded during the system boot routine and
will remain resident on the drive. This is accomplished by following one of the two
installation procedures listed in this section: new SCO UnixWare installation or
adding the device drivers to an existing SCO UnixWare system. (There are also
procedures listed for using multiple Adapters and for removing the driver.) These
procedures differ significantly from one another. We strongly suggest that you
carefully read the instructions for the procedure you plan to use and make sure
you understand them before proceeding with the corresponding systemconfiguration changes. In addition, Driver Disk 2 contains a README.TXT file
that might contain important updated information about the procedures
described in this chapter; we recommend that you read it and use it when you
perform the driver installation.
The Adapter’s interrupt-request level (IRQ) must be set to IRQ 10 for the driver
to install properly. Please refer to your system documentation to set the interrupt
levels and your peripheral documentation for help in setting SCSI IDs.
5.9.1 INSTALLING THE DRIVER IN A NEW UNIXWARE SYSTEM
SCO UnixWare drivers for the Ultra2 LVD SCSI Host Adapter are on Driver Disk 2.
In most cases you will load the drivers during a new installation of UnixWare from
CD-ROM. The driver is loaded during the early stages of the installation
procedure. The UnixWare installation program will prompt you for the required
parameters as the installation procedure progresses. We highly recommended that
you have copies of the SCO UnixWare Installation Handbook and SCO UnixWare
System Owner Handbook for reference.
1. Insert the SCO UnixWare Installation Diskette in the floppy drive and turn on
the computer. Follow the on-screen installation instructions.
2. When prompted to “Install Host Bus Adapter Drivers,” insert Driver Disk 2 in
drive A: and press <ENTER>.
3. When prompted to “Install Another HBA Diskette,” press <ENTER> to continue.
76
CHAPTER 5: Driver Installation
4. Follow the directions on screen until you come to a window titled “Loading
Initio INI-A100U2W Host Adapter.” Select “Continue Installation.” Select
“Continue Installation” again.
5. This completes loading the Adapter driver. Follow the on-screen directions to
complete the SCO UnixWare installation. For further information regarding
UnixWare installation, refer to the SCO UnixWare Installation Handbook.
5.9.2 ADDING THE DRIVER TO AN EXISTING UNIXWARE SYSTEM
1. Once a UnixWare session is established and a command prompt is ready, type
these lines (recall that UnixWare is case-sensitive):
cp /stand/unix /stand/unix.org <ENTER>
pkgadd -d diskette1 <ENTER>
2. Select “a100 ihv hba” from the list of available host drivers and press
<ENTER>.
3A. If the Ultra2 LVD SCSI Host Adapter is intended to be the bootable host adapter, the
next step to updating the driver will require a revision to the “a100” file.
These instructions will guide you through changing the current software
settings for UnixWare to establish the Ultra2 LVD SCSI Host Adapter as the
host adapter for your boot device:
a. At the system command prompt, type “cd /etc/conf/sdevice.d <ENTER>”.
b. Use “vi” or another editor to add a line to the “a100” file: Locate the line
“$version2” and add the line “$static” immediately after it.
c. Rebuild the UnixWare kernel by typing in these lines at the command
prompt:
/etc/conf/bin/idbuild -B <ENTER>
cp /etc/conf/cf.d/unix /stand/unix <ENTER>
cd / <ENTER>
shutdown -g0 <ENTER> (the “0” in “-g0” is a zero)
Y <ENTER>
77
ULTRA2 LVD SCSI HOST ADAPTER
3B. If the Ultra2 LVD SCSI Host Adapter is NOT intended to be the bootable host adapter,
these instructions will guide you through changing the current software
settings for UnixWare to establish the Ultra2 LVD SCSI Host Adapter as a nonbootable host adapter for your device. At the system command prompt, type
/etc/conf/bin/idbuild -Ma100 <ENTER>
cd / <ENTER>
shutdown -g0 <ENTER>
(the “0” in “-g0” is a zero)
Y <ENTER>
4 Exit the UnixWare program and reboot your system to initialize the new
device driver to control the Adapter.
5.9.3 USING MULTIPLE HOST ADAPTERS
UnixWare is capable of supporting up to eight SCSI buses. If you choose to use
multiple host adapters in your system—even if they are different models or
makes—verify that each host adapter’s shared interrupt level is set to IRQ10. Please
refer to your system documentation to set the interrupt levels.
You should configure and allocate space for each host adapter in the system by
making sure there is a separate line for each adapter in the “/etc/conf/sdevice.d/
a100” file. Make sure that “Y” is selected in the second field of each of these lines
that correspond to one of our Ultra2 LVD SCSI Host Adapters, so that their I/O
can be handled by the a100 driver that was designed for them. UnixWare will
automatically rebuild the kernel when an additional Adapter is detected.
78
CHAPTER 5: Driver Installation
5.9.4 REMOVING THE DRIVER FROM A UNIXWARE SYSTEM
1. Once a UnixWare session is established and a command prompt is ready, type
“/etc/conf/bin/idinstall -d a100 <ENTER>” (recall that UnixWare is casesensitive) to delete these files:
/etc/conf/mdevice.d/a100
/etc/conf/sdevice.d/a100
/etc/conf/pack.d/a100/driver.o
/etc/conf/pack.d/a100/space.c
/etc/conf/pack.d/a100/disk.cfg
2. Then rebuild the UnixWare kernel by executing the following commands at
the system prompt:
/etc/conf/bin/idbiuld -B -K <ENTER>
/cp /etc/conf/cf.d/unix /stand/unix <ENTER>
cd/ <ENTER>
shutdown -g0 <ENTER>
(the “0” in “-g0” is a zero)
Y <ENTER>

ULTRA2 LVD SCSI HOST ADAPTER
6. Troubleshooting
6.1 Installation-Time Problems
If you have difficulty installing your Ultra2 LVD SCSI Host Adapter, check these
things first:
1. Have you installed the Adapter in a PCI Rev. 2.0 compliant computer?
2. Are all SCSI devices powered?
3. Are all SCSI bus cables and power cables properly connected? Is Pin 1
oriented correctly?
4. Do the Adapter and all devices on the SCSI bus have unique IDs?
5. Are all devices on the SCSI bus terminated properly?
6. Is the drive type in your motherboard’s CMOS setup set to “Not installed”?
7. Does your system CMOS setup require you to enable PCI bus parameters? If
so, see your computer’s documentation. Check that IRQ-channel assignment
and BIOS settings have been made.
8. Did you install your Adapter in a PCI slot capable of busmastering? Refer to
your computer’s documentation or try another slot.
Here are some commonly asked questions and answers regarding problems that
can be encountered during the installation of an Adapter:
• Question: What is Ultra2 SCSI?
Answer: Ultra2 is a high-level SCSI specification. Because they use Low Voltage
Differential (LVD) technology, which is designed into the chipset and is less
susceptible to noise and uses less power than earlier SCSI implementations,
Ultra2 devices such as the Adapter are able to support Ultra2 Wide SCSI
peripherals with a SCSI burst-transfer speeds up to 80 Megabytes per second
and point-to-point (Adapter-to-single-device) cable lengths up to 25 meters
(82 ft.) or multipoint (Adapter-to-multiple-devices) cable lengths up to
12 meters (39.4 ft.).
80
CHAPTER 6: Troubleshooting
• Question: Can I use the Adapter with my legacy Ultra SCSI, SCSI-2, and SCSI-1
devices?
Answer: Yes, as long as they’re single-ended; but the Adapter’s SCSI bus will
become limited to (a) the top speed supported by your slowest device and
(b) the maximum length supported by your shortest-distance device. The
Adapter does not work with older differential SCSI devices.
• Question: Can I use the same cables for Ultra2 SCSI devices as I use for regular
Ultra SCSI peripherals?
Answer: We recommend that you use cables specifically designed for Ultra2
devices. The Adapter comes with a terminated Ultra2 Wide cable with
connectors for four internal Ultra2 peripherals.
• Question: Why isn’t the banner “!!!Press < Ctrl > < I > to start Configuration
Utility !!!” displayed when I power up the host system?
Answer: Verify that the Adapter is securely seated in its PCI slot, and that its
slot actually supports busmastering.
• Question: At bootup the message “SCSI BIOS Installed” is displayed, but the
system hangs.
Answer: Verify that the CMOS interrupt structure is set to INTA (interrupt A)
and that the CMOS IRQ level matches the jumper setting on the motherboard.
Refer to your PC’s user's manual.
• Question: At bootup, not all the peripherals are scanned and recognized.
Answer: Verify that each of the SCSI devices on the bus has its own distinct
SCSI ID number and that all peripherals are receiving power. Refer to your
peripherals’ manuals for information about changing SCSI IDs.
Verify that the SCSI termination is set correctly. Make sure that either the
cable itself or the last peripheral on the SCSI bus is terminated. See the
peripherals’ manuals for information about proper termination.
After you take the above steps, if the Adapter is still not recognizing all
attached peripherals, configure the Adapter to operate asynchronously by
changing the “Asynchronous Transfer” setting in the Device Setup Menu of
the firmware Setup Utility (see Section 4.6.3).
• Question: At bootup, the message “Missing Operating System” is displayed.
Answer: Is the boot drive larger than 1 GB? If so, verify that the “DOS Space >
1GB” is enabled in the Device Setup Menu of the firmware Setup Utility (see
Section 4.6.3).
81
ULTRA2 LVD SCSI HOST ADAPTER
• Question: Is it really necessary to terminate the last SCSI device on the cable?
Answer: Not if the cable itself is terminated. But if the cable is not terminated,
you must make sure that the device is terminated. Improper termination at
either end of the SCSI bus will cause the Adapter not to work properly, or even
not to initialize at all (the driver will fail to load).
• Question: How do I set the burst-transfer rate for SCSI devices?
Answer: You can set the maximum synchronous transfer rate of a given device
with the SmartSCSI Utility. To run the Utility, press <Ctrl> <I> at system
bootup; click on “Device Setup” and follow the on-screen options to select the
desired transfer rate (see Section 4.6.3).
• Question: Under SCO UnixWare®, the system displays a panic message or
crashes during bootup.
Answer: Reboot the system and verify that the interrupt setting of the
Adapter’s kernel conforms to UNIX standards. Please refer to your system’s
documentation for information about setting the interrupt levels and your
peripherals’ documentation for help in setting SCSI IDs.
In order to boot from the old UnixWare kernel, reboot the system and take
the following steps:
1. Begin an interactive boot session by pressing the space bar at the BOOTING
UNIXWARE prompt.
2. At the system’s [boot]# prompt, type KERNEL=unix.org < ENTER >.
3. Type go < ENTER >.
Consult the SCO UnixWare Installation Handbook’s “Troubleshooting” section to
help isolate the problem. If it becomes necessary to remove the Adapter’s SCO
UnixWare device driver, refer to Section 5.8.4.
