to the I/O signals of an I/O board which are available on the I/O
board’s J5 connector.
Caution
• The IOBP-IO720 is especially designed for the I/O board variants
of the PENT/CPCI-72x. Do not use any other I/O panels on the I/O721.
• Never connect SCSI devices to both SCSI connectors on board the
IOBP-IO720. Decide whether you want to use 16-bit or 8-bit SCSI.
• Never connect devices to both connectors on board the IOBPIO720 which carry the PMC user I/O signals. Decide whether you
want to use the full or only the partial range of PMC 2 user I/O signals.
The I/O panel includes an on-board flat cable and industry standard
connector for the PMC user I/O signals and for the SCSI signals.
PMC Module
The I/O-721 provides one PMC slot. If the I/O-721 is shipped without

2 - 12
PENT/CPCI-721
Installation
Hardware Upgrades and Accessories
Note:
• To ensure proper EMC shielding, always operate a
PENT/CPCI-721 with the blind panels for the PENT/CPCI-721
front panel or with the modules installed.
• If the PENT/CPCI-721 is upgraded, ensure that the blind panels
are stored in a safe place to be used again when removing the
upgrades.
The PMC slot supports 32-bit data bus width with a maximum frequency of 33 MHz. A power supply of +/- 12V is available at the PMC slots.
Voltage Keys
The PCI bus uses a 5V voltage signal level on the PMC slots. The voltage
keys prevent 3.3V PMC cards from being plugged into the PMC slots.
Connector Configuration
The 32-bit PCI bus requires two PMC connectors. The third PMC connector connects additional user I/O signals of the PMC slot with the
I/O-721 CompactPCI J5 connector. The CPU board provides a limited
current at the PMC supply pins.
Note: On the I/O-721, the PMC slot 1 provides three PMC connectors
(see Figure 7 “Mounting Points 2M1, ..., 2M5 of PMC Module on the
I/O-721” on page 2-14).
The different PMC slot numbering also results in a different pinout for
the I/O board’s CompactPCI connector and for the PMC user I/O connectors provided on the IOBP-IO720.
Caution
The total maximum power consumption per PMC slot at +/-12V, 5V
and 3.3V level must not exceed 7.5W (total over all used voltages).

Battery
Installation
Battery
The board is designed to be maintenance-free. However, note that a
Lithium battery is installed on the board. The battery provides a data
retention of five years summing up all periods of actual battery use.
Therefore Force Computers assumes that there usually is no need to
exchange the Lithium battery except for example in the case of longterm spare part handling.
Caution
• Incorrect exchange of Lithium batteries can result in a hazardous
explosion.
• Exchange the battery before five years of actual battery use have
elapsed.
• Exchanging the battery always results in data loss of the devices
which use the battery as power backup. Therefore, back up
affected data before exchanging the battery.
• Always use the same type of Lithium battery as is already
installed.
• If the battery is covered by a PMC module on slot 1 or a memory
module, the module must be removed first.
• Do not use a screwdriver to remove the battery from its holder to
avoid possible damage to the PCB or the battery holder.
• When installing the new battery ensure that the ‘+’ on top of the
battery stays at the top and therefore is visible when viewing the
board from its component side.
• If necessary reinstall the PMC or memory module in its correct
position.

Front Panel
Keys
The PENT/CPCI-721 provides front panel keys which will be described
below.
Reset Key
When enabled and toggled, it instantaneously affects the CPU board by
generating a reset. The reset generates a PCI reset and is programmable
to be globally or local to the CPU board via the PCI Bus Control Register.
A reset of all on-board I/O devices and the CPU is performed when the
reset key is pushed to the active position. RESET is held active until the
key is back in the inactive position, however at least 200 ms are guaranteed by a local timer. Power fail (below approximately 4.7V) and power
up – both lasting at least 200 ms to 300 ms – also force a reset to start the
CPU board.
Abort Key
When enabled and toggled, it instantaneously affects the CPU board by
generating an interrupt request (NMI) via the PCI-to-ISA bridge. This
allows to implement an abort of the current program, to trigger a selftest or to start a maintenance program.
Note: For information on how to disable the keys, see the “Action
Plan” section on page 2-10.

The PENT/CPCI-72x is designed to run with Windows NT Version 4.0.
The initial boot-up procedure is performed by BIOS which provides the
following features:
• Upgradable via software utility
• PCI 2.1 compliant
• Plug-and-Play 4.0 compliant (PnP)
• DMI 2.00.1 BIOS support
• Advanced Power Management
• Hardware setup
• Hardware initialization at boot: At power on or reset, BIOS performs
Power-On Self Test (POST) routines to test system resources. Afterwards it loads and starts the operating system.

BIOS provides the Setup program to configure the setting of a wide
range of system board features.
Press <F2> to enter Setup. The following options are displayed:
• LPT, COM1 and COM 2 can be remapped via the advanced configuration option for integrated peripherals in BIOS setup.
• The IDE devices can be configured via the main configuration
options for primary and secondary IDE masters and slaves and via
the advanced configuration option for intergrated peripherals. This
configuration capability is used for example at the first boot after
connecting an IDE device.
• The floppy type can be configured via the respective main configuration options for diskettes. This configuration capability is used for
example at the first boot after installing a floppy via the respective
I/O panel.
• The video system type can be configured via the related main configuration option. This configuration capability is for example used
at the first boot after installing the VGA accessory kit.

Boot Configuration
BIOS
Boot Configuration
The boot configuration options in Setup let you select the order of the
devices from which BIOS attempts to boot the operating system. During
POST, BIOS tries the next one on the list if it is unsuccessful at booting
from one device.
Each device listed represents the first of a group of devices if more than
one device of this group is installed on the system. For example, if there
is more than one hard disk drive, the displayed entry represents the first
of these drives as specified in the boot configuration option for fixed
media. The same applies to removable media.
The same options determine the order in which POST installs the devices and the operating system assigns device letters. BIOS supports up to
two floppy devices, to which the operating system may assign, for example, drive letters A: and B:.
C:, D:, E:, etc. are assigned to hard-disk drives.
Note: There is not always an exact correspondence between the order
specified in these menus and the letters assigned by the operating
system. Many devices such as legacy option ROMs support more than
one device, which can be assigned more than one letter. If you want
the CD-ROM drive to be listed before the hard drive, move it in front
of the hard drive. The group of bootable add-in cards refers to devices
with non-multiboot-compliant BIOS option ROM from which you
can boot the operating system.

Figure 30: Sample Setup Showing the Boot Configuration Options
In the example above BIOS attempts to boot in the following order:
1. Diskette Drive - from floppy disk
2. Removable Devices
3. Hard Drive - from hard disk
4. ATAPI CD-ROM Drive
Note:
• If you save changes you made in Setup, the selections in the
menus are stored in NVRAM (CMOS). The next time the system
board boots, BIOS configures the system according to the Setup
selections stored in NVRAM (CMOS). If those values cause the
system boot to fail, reboot and press <F2> to enter Setup. In Setup,
you can get the default values or try to change the selections that
caused the boot to fail.
• If you get the default values, note that the displayed default values are not yet stored to be effective for the next boot. They are
just loaded to be displayed. However, they are effective when the
current boot-up procedure is resumed.

Note:
• The NVRAM (CMOS) values may have been corrupted or modified incorrectly, perhaps by an application program that changes
data stored in NVRAM (CMOS). BIOS detects such problems by
verifying a so-called "System CMOS Checksum".
• If, during bootup, BIOS detects a problem in the integrity of values stored in NVRAM (CMOS), it displays a message asking you
to choose between boot continuation or entering Setup with the
ROM default values already loaded into the menus.
• After entering Setup with the ROM default values already loaded

SCSI BIOS
SCSI BIOS
Features
Features
The SCSI BIOS must be enabled if you want the system to boot from a
SCSI hard disk drive connected to the adapter. If the devices on the SCSI
bus are controlled by device drivers and therefore do not need a BIOS,
you can disable the SCSI BIOS to free about 16 KBytes of memory. This
also shortens the boot time by up to 60 seconds.
The SCSI BIOS provides two functions to support user configuration:
• Listing of the actually used SCSI IDs and correlated LUNs
• Setup options to adapt the CPU board and its SCSI configuration to
the user’s needs. The default configuration is marked within SCSI
BIOS Setup.
The SCSI IDs are listed during boot up when entering SCSISelect. You
can list actually assigned SCSI IDs within the BIOS Setup when you select the SCSI disk utilities from the initial SCSI BIOS Setup screen.
If you need to know the available LUNs, select the SCSI device you
want to configure. If there are multiple logical units, SCSI BIOS displays
a menu of correlated LUNs.
Some Setup options apply to the host adapter; other options apply individually to each device on the SCSI bus. In some cases the allowable value range depends on the actual SCSI bus width used (8-bit or 16-bit).
Some Setup options list the current device settings for each SCSI ID,
even IDs not assigned to a device.
PENT/CPCI-721

Features
SCSI BIOS
Note:
• In case of display problems press <F5> to toggle the display
between color and monochrome. This feature may not work on all
monitors.
• The default settings are appropriate for most applications, so there
usually is no need to change the settings. If you have to change the
settings of the advanced configuration options listed below, you
should ensure that you thoroughly understand the consequences
of the change before actually doing so.
Selectable Host Adapter SCSI ID
SCSI IDs range from 0…7 if the respective device is operated on an 8-bit
SCSI bus and from 0…15 on a 16-bit SCSI bus. For 8-bit devices, ID 7 has
the highest priority and ID 0 has the lowest priority. For l6-bit devices,
the priority of IDs is 7 … 0, then 15 … 8. In this case, ID 7 has the highest
priority and ID 8 has the lowest priority. Each host adapter (8- or 16-bit)
has the default SCSI ID of 7, which gives the adapter the highest priority
on the SCSI bus.
Note: Host adapter SCSI termination: The configuration of the host
adapter SCSI termination within SCSI BIOS is not supported because
the SCSI termination is controlled by SW0900C and SW0900D (see
page 2-13).
SCSI Parity Checking
Each adapter uses SCSI parity checking to verify the accuracy of data
transfer on the SCSI bus. Most currently available SCSI devices support
SCSI parity check. If a device on the SCSI bus does not support it, disable parity checking.
Selectable Boot Device
Selectable boot device by specifying the boot target ID (and LUN in case
the device has implemented multiple logical units).
5-4
PENT/CPCI-721
SCSI BIOS
Features
Selectable Settings For Synchronous Data Transfer
Synchronous data transfer is faster than asynchronous data transfer:
• If the adapter is set not to negotiate for synchronous data transfer,
the value to be selected will be the maximum rate at which the
adapter accepts data from the device during negotiation. This is
standard SCSI protocol. The values displayed assume that UltraSCSI
support is enabled (see the respective advanced configuration
option shown below). If not, the speeds are half those shown.
• Most SCSI devices support synchronous negotiation. If a device
does not support synchronous negotiation, the adapter will automatically transfer the data in asynchronous mode.
• Specification of the maximum sync transfer rate: The maximum synchronous data transfer rate determines the rate that the adapter
negotiates with the device. The adapter automatically negotiates for
the rate requested by the device.
• Sync negotiation: Synchronous negotiation is a SCSI feature that
allows the SCSI adapter and its attached SCSI devices to transfer
data in synchronous mode. The setting determines whether the
adapter initiates synchronous negotiation with the SCSI device.
However, the adapter always responds to synchronous negotiation
if the SCSI device initiates it. If neither the adapter nor the SCSI
device negotiates for synchronous data transfers, data will be transferred in asynchronous mode.
Enabling Disconnection
Enabling disconnection allows a SCSI device to disconnect from the
SCSI bus (sometimes called Disconnect/Reconnect). It allows the
adapter to perform other operations on the SCSI bus while the SCSI
device is temporarily disconnected. The SCSI device may choose not to
disconnect, however, even if permitted by the adapter (this can usually
be configured on the SCSI device). Leave this option set to yes if the
adapter connects to two or more SCSI devices. This optimizes SCSI bus
performance. If the adapter connects to only one SCSI device, set enable
disconnection to no to achieve slightly better performance.
PENT/CPCI-721
5-5
Features
SCSI BIOS
Send Start Unit Command
Enabling the adapter to send the SCSI start unit command to the SCSI
device (SCSI command 1B) reduces the load on a system’s power supply by allowing the adapter to turn on SCSI devices one by one when
the system boots. Otherwise, all SCSI devices are turned on at the same
time. Before you enable this option for a device, check the device documentation to make sure the device supports the command. On most
devices, you must also change a switch or jumper setting on the device
to enable the device to respond to the command. If you enable the SCSI
start unit command for more than one SCSI device, the adapter first
sends the command to the boot device specified in SCSI BIOS. When
this device responds, further commands are sent to the remaining
devices, beginning with the device with lowest SCSI ID. The boot time
varies depending on how long each drive takes to spin up.
Initiate Wide Negotiation
Initiating wide negotiation is possible: If the host adapter is enabled to
initiate wide negotiation, it lets the adapter initiate wide negotiation
with a 16-bit SCSI device only. The adapter will not attempt wide negotiation with 8-bit devices. So you can leave this option enabled even if
the bus includes 8-bit devices.
5-6
PENT/CPCI-721
SCSI BIOS
Advanced Configuration Options
Advanced Configuration Options
The SCSI BIOS includes the following advanced configuration options.
Plug-and-Play Support
When Plug-and-Play support is enabled, the adapter automatically
assigns a SCSI ID to an attached SCSI device that supports the SCAM-1
protocol. Most non-SCAM devices tolerate SCAM protocol, so this
option can usually be enabled even in case of some non-SCAM devices.
However, in rare cases, an old SCSI-l device may not tolerate SCAM
and may cause the system to hang or operate erratically.
Support for Removable Disks
Setting the support for removable disks under BIOS as fixed disks controls which removable-media drives are supported by the SCSI BIOS.
The following choices are available:
• Boot only: Only the removable-media drive designated as the boot
device is treated as a hard disk drive.
• All disks: All removable-media drives supported by the SCSI BIOS
are treated as hard drives.
• Disabled: No removable-media drives running under DOS are
treated as hard disk drives. In this situation, driver software is
needed, because the drives are not controlled by the SCSI BIOS.
Extended Translation Scheme for DOS Drives > 1 GByte
All current MS-DOS versions are limited to 1024 cylinders per drive.
The standard translation scheme for SCSI host adapters, using 64 heads
and 32 sectors, provides a maximum accessible capacity of 1 GByte. To
support disk drives larger than 1 GByte, the SCSI BIOS includes an
extended translation scheme that supports disk drives as large as 8
GBytes under MS-DOS. With extended translation enabled, drives handled by the SCSI BIOS use extended translation if their formatted capacity is greater than 1 GByte, and drives smaller than 1 GByte use
standard translation.
PENT/CPCI-721
5-7
Advanced Configuration Options
SCSI BIOS
Note: Loss of data: If you decide to change the translation scheme,
back up the disk drives first! All data is erased when you change from
one translation scheme to another.
When you partition a disk larger than 1 GByte, use the MS-DOS fdisk
utility as you normally would. Because the cylinder size increases to
8 MBytes under extended translation, the partition size you choose
must be a multiple of 8 MBytes. If you request a size that is not a multiple of 8 MBytes, fdisk rounds up to the nearest whole multiple of 8
MBytes.
Multiple LUN Support
When enabled, the BIOS supports multiple logical units. Enable this
option if any devices have multiple logical units.
BIOS Support for Bootable CD-ROM
Leave the BIOS support for bootable CD-ROM enabled to boot from a
CD-ROM. If booting from a hard disk or other device, make sure no
bootable CD-ROM is installed, or disable this option.

no harm.

I/O Board LED Control Register
The I/O board LED control register is implemented on-board the I/O
board via the General Purpose I/O register (GPIO) of the PCI-to-PCIbridge. The PCI-to-PCI-bridge with device number 1910 (IDSEL 3010) is
located at PCI bus 0. The GPIO is integrated in the PCI configuration
space of this PCI-to-PCI-bridge at offset 6416. It controls the status of the
I/O board front panel user LED.
The front panel LED 4 of the I/O board is connected to GPIO3 of the
PCI-to-PCI-bridge on-board the I/O board.
Note: The bits denoted as ‘x’ in the following values must remain unaltered.
LED Off
To switch off the user LED, set the GPIO register to the following value
via a 32-bit write access (from left to right 6716 to 6416):
xxxx.xxxx.0001.0000.0000.0001.xxxx.xxxx2
LED Green
To switch on the user LED, set the GPIO register to the following value
via a 32-bit write access (from left to right 6716 to 6416):
xxxx.xxxx.0000.0001.0000.0001.xxxx.xxxx2
