Installation Steps

Before using your computer, you must complete the following steps:

1. Set Jumpers on the Baseboard

2. Install DRAM Memory Modules

3. Install the Central Processing Unit (CPU) Card

4. Install Expansion Cards

5. Connect Ribbon Cables, Cabinet Wires, and Power Supply

6. Setup the BIOS Software (see the CPU Card BIOS section)

1. Jumpers

Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the baseboard. See “Baseboard Layout” on page 10 for locations of
jumpers. The jumper settings will be described numerically such as [----], [1-2],

(Jumpers)

[2-3] for no connection, connect pins 1&2, and connect pins 2&3 respectively. Pin
1 for our baseboards is always on top
baseboard with the keyboard connector away from yourself. A “1” is written be-

sides pin 1 on jumpers with three pins. The jumpers will also be shown graphically
such as
two pins will be shown as for short (On) and for open (Off). 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.

WARNING! Computer motherboards, baseboards and components, such as SCSI

cards, contain very delicate Integrated Circuit (IC) chips. To protect them against
damage from static electricity , you should follow some precautions whenever you
work on your computer.

2. System Memory (DRAM/SDRAM & SRAM)

This baseboard supports eight 72-pin SIMMs (Single Inline Memory Modules) of
4MB, 8MB, 16MB, 32MB, 64MB to form a memory size between 8MB to 512MB.
The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmet­ric), Extended Data Output (EDO), or Burst Extended Data Output (BEDO) (with
C-P6ND only). SIMMs must be installed in pairs so that each bank contains two of
the same size memory modules. To support ECC, you must use true (opposed to
phantom parity generated by TTL chips) 36-bit parity-type SIMM (e.g. 8 chips + 4
parity chips) in pairs for all modules. Mixing 32-bit non-parity SIMM (e.g. 8 chips)
and 36-bit SIMM (e.g. 12 chips) will work minus the ECC feature.

IMPORTANT: Memory setup is required in “Auto Configuration” in the
CHIPSET FEATURES SETUP of Section IV BIOS software. Each bank must
have the same size memory installed in pairs.

(Memory)

Install memory in any or all of the banks in any combination as follows:

Bank Memory Module Total Memory

Bank 0 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Slots 1&2 72-pin FPM, EDO, BEDO SIMM

SIMM Slots 5&6 72-pin FPM, EDO, BEDO SIMM

Bank 3 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Slots 7&8 72-pin FPM, EDO, BEDO SIMM

NOTE: Memory on socket 1 has a clearance of 5.0 cm when the C-PKND and
C-P6ND CPU cards are installed and 5.5 cm when the C-P55T2D CPU card is installed.

NOTE: SIMM numbers are not in sequence, (2, 4, 6, 8, 1, 3, 5, 7 from left to right.)
IMPORTANT: Each bank must have the same size memory installed in pairs. 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 be
unstable.

DRAM Memory Installation Procedures

IMPORTANT: Install memory modules in symmetric pairs.

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.

3. Central Processing Unit

The P/I-P65UP5 baseboard provides a CPU card slot that can be used with any ASUS
CPU cards, which are available separately. You must purchase any one of these CPU
cards (see next page for a brief description) to complete the system’ s board.

System Case

The system case must be either a mid- to full-size tower or desktop (for C-P6ND
and C-P55T2D CPU cards) or server (C-PKND) case to give a clearance as follows:

The P/I-P65UP5 baseboard is a standard 3/4 baby AT size 11 x 8.75” and will fit
almost all system cases, but the CPU card will require that the floppy disk and CD­ROM drives not be hanging over the baseboard. Depending on the height of the SIMM
memory modules and the CPU fan and/or heatsink, the area above the SIMM memory
modules may not be available. For both the C-P6ND and C-P55T2D CPU cards, be
sure that your case has a minimum area clearance of 11 x 9.25 x 5” (28.5 x 23.5 x 12.7
cm), and for the C-PKND CPU card, 13.5 x 9.25 x 5” (34.3 x 23.5 x 12.7 cm).

One end of the CPU card has a bracket, which should slide into the system case front
panel. Be sure that the system case can support a long PCI card on the first slot and
that a groove is available for the bracket. Refer to your respective CPU card’ s docu­mentation for details.

General Installation Procedures for the ASUS CPU Card:

1. Remove the CPU card from its packaging without touching the integrated circuit
(IC) chips, connectors, and other components. Place it onto the antistatic bag.

2. Follow instructions in the CPU card manual on installing the processor/s, sup­port bracket, and setting jumpers.

3. Remove the expansion slot cover for the first slot.

4. Carefully align the CPU card over the CPU Card Slot (CPU SLOT A and CPU
SLOT B).

5. Be sure that the card is perpendicular to the baseboard. Firmly press one end of
the card halfway in, the other end halfway in, then the first end completely in,
and finally, the second end completely in. Be sure that all the connectors are
evenly inserted into the slots.

6. Screw in the metal bracket to the system case.

WARNING! Move the system carefully and only with the power off because

the CPU card is heavy as well as delicate.

4. Expansion Cards

First read your expansion card documentation on any hardware and software set­tings that may be required to set up your specific card.

NOTE: PCI Slot 5 has a MediaBus extension, which allows the installation of either
a PCI card or a MediaBus card (optional multifunctional card).

WARNING! Unplug your power supply when adding or removing expansion

cards or other system components. Failure to do so may cause severe damage to
both your baseboard and expansion cards.

PCI SETUP)

Assigning IRQs for Expansion Cards

IMPORTANT: PCI Slots 4 & 5 share the same IRQ. If using PCI cards on both
slots 4 & 5, make sure that the drivers support “Share IRQ” or that one card does not
need an IRQ assignment. Conflicts will arise on PCI Slots 4 & 5 that will make the
system unstable.

Some expansion cards need to use an IRQ to operate. Generally an IRQ must be
exclusively assigned to one use. In a standard design there are 16 IRQs available but
most of them are already in use, leaving 6 IRQs free for expansion cards.

Both ISA and PCI expansion cards may require to use IRQs. System IRQs are avail­able to cards installed in the ISA expansion bus first, then any remaining IRQs are
available to 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

III. INSTALLATION

bus. You may use Microsoft Diagnostics (MSD.EXE) utility located in the Win­dows directory to see a map of your used and free IRQs. If you use W indows 95, the
Resources tab under Device Manager displays the resource settings being used by
a particular device (to gain access, double-click the System icon under the Control
Panel program). Ensure that no two devices share the same IRQs or your computer
will experience problems when those two devices are in use at the same time.

T o simplify this process, the baseboard complies 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 section
of the BIOS setup utility can be used to assign which IRQs are being used by legacy
cards. For older legacy cards that do not work with the BIOS, you may contact your
vendor for an ISA Configuration Utility.

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 contains a card requiring an IRQ. T o install a PCI card, you
need to set the INT (interrupt) assignment. Since all the PCI slots on this baseboard
use an INTA #, set the jumpers on your PCI cards 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 baseboard are handled the same way as
the IRQ assignment process described earlier . Y ou can select a DMA channel in the
PCI and PnP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy
ISA cards (under PNP AND PCI SETUP of the BIOS SOFTWARE, choose Yes in
IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to
reserve).

This allows the user to manually place the system into a suspend mode or “Green”
mode where system activity will be instantly decreased to save electricity and ex­pand the life of certain components when the system is not in use. This 2-pin con­nector connects to the case-mounted suspend switch. If the switch is not available,
you can use the turbo switch. SMI is activated when it detects a short to open mo­ment; leaving it shorted, therefore, will not cause any problems. This may require
one or two presses depending on the switch’s position. Wake-up can be controlled
through the BIOS but the keyboard will always wake up (the SMI lead cannot wake
up) the system. If you want to use this connector , the “Suspend Mode” under Power

IV. ASUS PCI SCSI Cards

Symbios SCSI BIOS and Drivers

Aside from the system BIOS, the Flash memory chip on the baseboard also contains
the Symbios SCSI BIOS. This Symbios SCSI BIOS works in conjunction with the
optional ASUS PCI-SC200 controller card to provide Fast SCSI-2 interface when
using compatible SCSI devices or the ASUS PCI-SC860 SCSI controller cards to
provide Ultra-Fast SCSI-2 interface when using Ultra-Fast SCSI-2 devices.

All SCSI devices you install on your system require driver software to function.
The Symbios 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 ASUS PCI-SC200 and ASUS PCI-SC860 controller card packages
to support hard disks and other SCSI devices working under DOS, Microsoft Win­dows, Microsoft Windows NT, Novell NetWare and IBM 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. W indows 95 support is also
available using the device drivers included within the W indows software. The ASUS
PCI-SC200 and ASUS PCI-SC860 are Plug and Play adapters that are autodetected
by BIOS and current operating systems that support Plug and Play features.

IV. ASUS SCSI Cards

(SCSI BIOS)

For information about these drivers and their usage, view the Readme files included
in the driver packages.

ASUS PCI-SC200 & PCI-SC860 SCSI Cards

The ASUS PCI-SC200 or the ASUS PCI-SC860 may be bundled with your base­board or purchased separately . Both cards provide the option of connecting internal
or external SCSI devices for a total of 7 devices on each SCSI card.

28 ASUS P/I-P65UP5 User’s Manual

Setting Up the ASUS PCI-SC200 & PCI-SC860

There are two jumper settings you may need to make on the ASUS PCI-SC200 to set
it up. One setting assigns the PCI INT interrupt, the other sets the card’ s termination.
The ASUS PCI-SC860 has no jumper settings (see Terminator Requirements”).

Setting the INT Assignment for the ASUS PCI-SC200

You must use PCI INT A setting to properly assign the ASUS PCI-SC200’s inter­rupt. On the ASUS 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 ASUS PCI-SC200 with this baseboard.

Terminator Requirements for SCSI Devices

SCSI devices are connected together in a “chain” by cables. Internal devices con­nect to the ASUS PCI-SC200 or ASUS PCI-SC860 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.” T erminating the devices on the ends of the SCSI Bus “chain”
is necessary for SCSI devices to work properly . Termination of the devices between
the ends must be Disabled.

(Setup)

IV. ASUS SCSI Cards

ASUS P/I-P65UP5 User’s Manual 29

IV. ASUS PCI SCSI Cards

Terminator Settings for the ASUS PCI-SC860

Many SCSI devices including the ASUS PCI-SC860 use a set of onboard active
resistors to terminate the devices at the ends automatically. Automatic termination
requires that the SCSI devices be connected in a straight linear connection or “chain.”
Connect SCSI devices to one or two of the SCSI connectors in a linear “chain” for
auto termination of the ASUS PCI-SC860 to be effective. Other formations will
cause your SCSI devices to not mount properly . You must use the end of the ribbon
cable when using the internal connector(s) to keep a linear path.

Additional Note: The Symbios Logic SCSI Configuration Utility is a powerful
tool. If, while using it, you somehow disable all your controllers or cannot enter
the configuration utility, pressing “Ctrl-A” after memory count during reboot
allows you to recover and reconfigure.

Terminator Settings for the ASUS PCI-SC200

The ASUS PCI-SC200, on the other hand, has “active” termination that you must
set using jumper JP5. There are two settings, “terminated” and “not terminated,” as
shown below.

IV. ASUS SCSI Cards

(Jumpers)

Decide whether or not you need to terminate the ASUS 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
ASUS PCI-SC200, then you must terminate the ASUS 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 for SCSI Devices

All SCSI devices, including the ASUS PCI-SC200 and ASUS PCI-SC860 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 ASUS PCI-SC200 and
ASUS PCI-SC860 cards have fixed SCSI IDs of 7. The SCSI ID serves two purposes:

• It uniquely defines each SCSI device on the bus.

• It determines which device controls the bus when two or more devices try to use
it at the same time.

SCSI IDs on one channel do not interfere with the IDs on another channel. This ap­plies to two SCSI host adapters that implement different buses as well as dual channels
on a single host adapter. You can connect up to seven SCSI devices to the interface
card. You must set a SCSI ID number (ID 0 to ID 6) 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 .

SCSI ID Priority

The ASUS PCI-SC200 and ASUS PCI-SC860 are 8bit single-channel SCSI cards.
SCSI ID 7 has the highest priority, and SCSI ID 0 has the lowest priority.
