III. INSTALLATION
(Jumpers)
Several hardware settings are made through the use of jumper caps to connect jumper pins (JP) on the motherboard. See "Map of the Motherboard"
on page 4 for locations of jumpers. The jumper settings will be described
numerically such as [----], [1-2], [2-3] for no connection, connect pins 1&2,
and connect pins 2&3 respectively. Pin 1 for our motherboards is always on
or on the left
when holding the motherboard with the keytop
board connector away from yourself. A "1" is written besides pin 1 on
jumpers with three pins. The jumpers will also be shown graphically such
as
to connect pins 1&2 and
to connect pins 2&3. Jumpers with
two pins will be shown as
for short and
for open. For manufacturing simplicity, the jumpers may be sharing pins from other groups. Use the
diagrams in this manual instead of following the pin layout on the board.
Settings with two jumper numbers require that both jumpers be moved together. To connect the pins, simply place a plastic jumper cap over the two
pins as diagramed.

3. Total Level 2 Cache Size Setting (JP2)
This jumper sets the total amount of L2 cache that is present. If you
have two cache chips on-board (see "Map of Motherboard" for locations), then you have either 256KB or 512KB. An "ASUS" or "COAST"
cache module can be used to upgrade the 256KB version to 512KB. If
there is no on-board cache, you must install a cache module of either
256KB or 512KB. IMPORTANT: See page 14 "SRAM Cache" for
installation procedures. Regardless of your cache combination, set
the following jumpers according to the total amount of L2 cache that is
present on-board and installed as a module.

These jumpers tells the clock generator what frequency to send to the
CPU. These allow the selection of the CPU’s External frequency (or
BUS Clock). The BUS Clock times the BUS Ratio equals the CPU's
Internal frequency (the advertised CPU speed).
6. CPU to BUS Frequency Ratio (JP9, JP10)
These jumpers set the frequency ratio between the Internal frequency of
the CPU and the External frequency (called the BUS Clock) within the
CPU. These must be set together with the above jumpers CPU External

2. System Memory (DRAM & SRAM)
This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB,
or 64MB to form a memory size between 8MB to 256MB. The DRAM can
be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmetric) or EDO.
To support ECC, you must use true (opposed to phantom parity generated
by TTL chips) 36-bit parity-type DRAM (e.g. 8 chips + 4 parity chips) in
pairs for all modules. Mixing 32-bit non-parity DRAM (e.g. 8 chips) and
36-bit DRAM (e.g. 12 chips) will work minus the ECC feature.
IMPORTANT: Memory setup is required in BIOS Chipset Setup "Auto
Configuration" on page 35.
Install two memory modules each time as shown in the chart below.

III. INSTALLATION
IMPORTANT: Do not use memory modules with more than 24 chips per module. Modules with more than 24 chips exceed the design specifications of the
memory subsystem and will cause unreliable operation.
IMPORTANT: Do not use SIMM Modules that use an extra TTL chip to convert the memory module from asymmetric to symmetric.
DRAM Memory Installation Procedures:
1. The SIMM memory modules will only fit in one orientation as shown
because of a "Plastic Safety Tab" on one end of the SIMM slots which
requires the "Notched End" of the SIMM memory modules.

Level 2 External Static RAM (SRAM) Cache
The motherboard you may purchase may have either 0KB, 256KB, or 512KB
on-board. If you have two cache chips on-board (see "Map of Motherboard" for locations), then you have either 256KB or 512KB pipelined bust
SRAM cache. An "ASUS" or "COAST" cache module can be used to upgrade the 256KB version to 512KB. The 512KB version cannot be upgraded any further. If there is no on-board cache, you may install a SIMM

3. Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible with ZIF Socket 5 processors. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not
the case then purchase a fan before you turn on your system. Apply thermal
jelly to the CPU top and then install the fan onto the CPU.
WARNING: Without a fan, the CPU can overheat and cause damage
to both the CPU and the motherboard. (See page 24 "CPU Cooling
Fan Connector).
III. INSTALLATION
(CPU)
To install a CPU, first turn off your system and remove its cover. Locate the
ZIF socket and open it by first pulling the lever sideways away from the
socket then upwards to a 90-degree right angle. Insert the CPU with the
correct orientation as shown. Use the notched corner of the CPU with the
white dot as your guide. The white dot should point towards the end the of
the lever. Notice that there is a blank area where one hole is missing from
that corner of the square array of pin holes and a "1" printed on the motherboard next to that corner. Because the CPU has a corner pin for three of the
four corners, the CPU will only fit in the one orientation as shown. The
picture is for reference only; you should have a CPU fan that will cover the
face of the CPU. With the added weight of the CPU fan, no force is required
to insert the CPU. Once completely inserted, hold down on the fan and
close the socket's lever.
IMPORTANT: You must set jumpers for "CPU to BUS Frequency
Ratio" and jumpers for "BUS Frequency Selection" on page 10 depending on the CPU that you install.

Read the documentation for your expansion card.
Set any necessary jumpers on your expansion card.
Remove your computer’s cover.
Remove the bracket on the slot you intend to use. Keep the bracket for
possible future use.
Carefully align the card’s connectors and press firmly.
Secure the card on the slot with the screw you removed in step 4.
Replace the computer’s cover.
Setup the BIOS if necessary.
Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally an IRQ
must be exclusively assigned to one use. In an standard design there are 16
IRQs available but most of them are already in use by parts of the system
which leaves 6 free for expansion cards.
Both ISA and PCI expansion cards may need to use IRQs. System IRQs are
available to cards installed in the ISA expansion bus first, and any remaining IRQs are then used by PCI cards. Currently, there are two types of ISA
cards. The original ISA expansion card design, now referred to as “Legacy”
ISA cards, requires that you configure the card’s jumpers manually and then
install it in any available slot on the ISA bus. You may use Microsoft's
Diagnostic (MSD.EXE) utility included in the Windows directory to see a
map of your used and free IRQs. For Windows 95 users, the "Control Panel"
icon in "My Computer," contains a "System" icon which gives you a "Device Manager" tab. Double clicking on a specific device give you "Resources" tab which shows the Interrupt number and address. Make sure that
no two devices use the same IRQs or your computer will experience problems when those two devices are in use at the same time.

P/I-P55T2P4 User's Manual
III. INSTALLATION
To simplify this process this motherboard has complied with the Plug and
Play (PNP) specification which was developed to allow automatic system
configuration whenever a PNP-compliant card is added to the system. For
PNP cards, IRQs are assigned automatically from those available.
If the system has both Legacy and PNP ISA cards installed, IRQs are assigned to PNP cards from those not used by Legacy cards. The PCI and
PNP configuration of the BIOS setup utility can be used to indicate which
IRQs are being used by Legacy cards. For older Legacy cards that does not
work with the BIOS, you can contact your vendor for an ISA Configuration
Utility.
III. INSTALLATION
(DMAChannels)
An IRQ number is automatically assigned to PCI expansion cards after those
used by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI slot that has a card in it that requires an
IRQ. To install a PCI card, you need to set something called the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an
INTA #, be sure that the jumpers on your PCI cards are set to INT A.
Assigning DMA Channels for ISA Cards
Some ISA cards, both Legacy and PNP may also need to use a DMA (Direct
Memory Access) channel. DMA assignments for this motherboard are
handled the same way as the IRQ assignment process described above. You
can select a DMA channel in the PCI and PNP configuration section of the
BIOS Setup utility. In the BIOS setup, you should choose "Yes" for those
IRQ's and DMA's you wish to reserve for Legacy cards.

ASUS MediaBus Card
MediaBus allows a cost-efficient solution to a complete multimedia system. The advantages of using one add-on card is to reduce the slot requirements and compatibility problems in order to maximize the Plug and Play
advantages. The add-on card inserts into the shared PCI 4/MediaBus 2.0
Slot.
NOTE: This motherboard uses MediaBus Rev. 2.0. The previous MediaBus cards designed for MediaBus Rev. 1.2 will not fit into the MediaBus Rev 2.0 that is on this motherboard.
III. INSTALLATION
(MediaBusCard)
The difference between Rev. 1.2 and Rev. 2.0 is that the later revision has
72 pins instead of 68 so it does not have to use any PCI slot signals reserved
for PCI cards, therefore the motherboard's PCI Slot 4 can meet standard
specifications. The gap between the MediaBus extension and the PCI
Slot 4 has been increased from 0.32" to 0.40" in order to prevent Rev. 1.2
MediaBus cards from being installed into the new motherboards and vice
versa.

Video BIOS Shadow
This field allows you to change the video BIOS location from ROM to
RAM. Relocating to RAM enhances system performance, as information
access is faster than the ROM. Setup default setting is Enabled.
C8000-CBFFF to DC000-DFFFF
These fields are used for shadowing other expansion card ROMs. If you
install other expansion cards with ROMs on them, you will need to know

The system automatically “wakes up” from any power saving mode when
there is system activity such as when a key is pressed from the keyboard, or
when there is activity detected from the enabled IRQ channels.
“HDD Power Down” shuts down any IDE hard disk drives in the system
after a period of inactivity. This time period is user-configurable to “1-15

NCR SCSI BIOS and Drivers
Aside from the system BIOS, the Flash memory chip on the motherboard
also contains the NCR SCSI BIOS. This SCSI BIOS works in conjunction
with the optional PCI-SC200 SCSI controller card to provide a complete
PCI Fast SCSI-2 interface.
All SCSI devices you install to your system require driver software to function. The NCR SCSI BIOS directly supports SCSI hard disks under the
DOS, Windows and OS/2 environments. It also uses device drivers from
the DOS floppy disk included in the PCI-SC200 controller card package to
support hard disks and other SCSI devices working under DOS, Windows,
Windows NT, Novell NetWare and OS/2. These drivers provide higher
performance than the direct BIOS support. To use these drivers, you must
install them into your system and add them to your system configuration
files. Driver support for SCSI devices used with SCO UNIX is also provided. These drivers are included in the second SCO UNIX floppy disk.
Windows 95 support is also available using the device drivers included within
the Windows software. The PCI-SC200 adapter is auto detected as PCI
NCRC810 SCSI HOST ADAPTER and uses the NCRC810.MPD driver.
For information about these drivers and their usage, see the Readme files
included in the driver packages. You can print out the contents of these files
using any text editor program.

system case to the internal connector on the card. You also have the additional option of connecting external SCSI devices to the external SCSI-2
connector on the card.
If you get the PCI-SC200 later on as an option, you will need to install it
yourself. The setup procedure is explained here.
Setting Up the PCI-SC200
There are two jumper settings you may need to make on the card to set it up.
One setting assigns the PCI INT interrupt, the other sets the card’s termination.

Setting the INT Assignment
You must use PCI INT A setting in order to properly assign the card's interrupt. On the PCI-SC200, you assign the INT by setting jumper JP1 or JP2.
The default setting for the card already is INT A, so you do not need to
change the setting to use the PCI-SC200 with this motherboard.

Terminator Settings
SCSI devices are connected together in a “chain” by cables. Internal devices connect to the PCI-SC200 with a fifty-pin flat ribbon cable. External
devices connect to the external port with a SCSI-2 cable. If there are more
than one internal or external devices, additional devices are connected with
cables to form a “daisy chain.” The SCSI chain must be “terminated” at
both ends, or the devices in the chain will not work properly.
V. PCI-SC200
(Jumpers)
Many SCSI devices use a set of terminating resistors to terminate the device. The PCI-SC200 has “active” termination that you set using jumper
JP5. If you need to terminate the PCI-SC200, you do it by setting the jumper.
The are two settings, "terminated" and "not terminated," as shown below.

V. PCI-SC200 SCSI Card
Decide whether or not you need to terminate the PCI-SC200 based on its
position in the SCSI chain. Only the devices at each end of the chain need to
be terminated. If you have only internal or only external devices connected
to the PCI-SC200, then you must terminate the PCI-SC200. If you have
both internal and external devices connected, you must not terminate the
card. See the following example which illustrates this concept.

(SCSI ID Numbers)
SCSI ID Numbers
All SCSI devices, including the PCI-SC200 interface card must have a SCSI
identification number that is not in use by any other SCSI device. There are
eight possible ID numbers, 0 through 7. The PCI-SC200 has a fixed SCSI
ID of 7.
You can connect up to seven SCSI devices to the interface card. You must
set a SCSI ID number for each device. SCSI devices vary in how they set
the ID number. Some use jumpers, others have some kind of selector switch.
Refer to the manual for any device you install for details on how to set its ID
number.
