Installation Steps

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

1. Set Jumpers on the Motherboard

2. Install System Memory

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

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

6. Setup the BIOS Software

1. Jumpers

Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See “Motherboard Layout” for locations of jumpers.
The jumper settings will be described numerically such as [----], [1-2], [2-3] for no

(Jumpers)

connection, connect pins 1&2, and connect pins 2&3 respectively . Pin 1 for our moth­erboards is always on top
the keyboard 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 (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.

when holding the motherboard with

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a
metal object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.

4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

Jumper Settings

1. Real Time Clock (RTC) RAM (RTCLR)

The CMOS RAM is powered by the onboard button cell battery. To clear the
R TC data: (1) T urn of f your computer and remove the AC power , (2) Move this
jumper to “Clear Data,” (3) Move the jumper back to “Operation,” (4) T urn on
your computer, (5) Hold down <Delete> during bootup and enter BIOS setup to
re-enter user preferences.

Battery Test Jumper (RTCLR)

You can test the battery’s current by removing this jumper and attaching a cur­rent meter to the “Operation” pins.

WARNING! You must unplug the power cord to your power supply to en-

sure that there is no power to your motherboard. The CMOS RAM con­taining BIOS setup information may be cleared by this action. You should
enter BIOS to “Load Setup Defaults” and re-enter any user information
after removing and reapplying this jumper.

2. VGA Setting (VGA_SEL) (with onboard VGA version only)

These jumpers allow you to turn the onboard VGA on or off if necessary. The
motherboard BIOS will automatically Enable or Disable the onboard VGA based
on whether a VGA card is in the expansion bus. You need to disable the onboard
VGA only if you have conflicts between the onboard VGA and a separate in­stalled VGA expansion card within your operating system.

3. CPU External (BUS) Frequency Selection (FS0, FS1, FS2)

These jumpers tell 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).

4. CPU to BUS Frequency Ratio (BF0, BF1, BF2)

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 (BUS) Frequency Selection.

2. System Memory (SIMM & DIMM)

This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Mod­ules) of 4, 8, 16, 32, or 64MB to form a memory size between 8MB to 256MB. The
SIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Sym­metric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). SIMMs
must be installed in pairs so that each Row (see Map of Motherboard for Row loca­tions) contains 64-bits of the same size and type of memory chips. One side (with
memory chips) of the SIMM module takes up half a Row on the motherboard.

Dual Inline Memory Modules (DIMM’s) can be used when the SIMM sockets are
not used. Two sockets are available for 3.3Volt (power level) Unbuffered Synchro-
nous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB to form
a memory size between 8MB to 256MB. One side (with memory chips) of the
DIMM module takes up one Row on the motherboard.

IMPORTANT: Memory speed setup is requir ed thr ough “Auto Configuration”
in BIOS Chipset Setup of the BIOS SOFTW ARE. If both 60ns and 70ns memory
are used, set “Auto Configuration” to 70ns. 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.

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.

WARNING! Without a fan circulating air on the CPU, the CPU can overheat

and cause damage to both the CPU and the motherboard.

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.

4. Expansion Cards

WARNING! Make sure that you 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 motherboard and expansion cards.

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

NOTE: PCI Slot 4 has a MediaBus extension which allows the installation of a PCI

card or a MediaBus card (optional multifunctional card) but not both.

III. INSTALLATION

(Expansion Cards)

Expansion Card Installation Procedure:

III. INSTALLATION

1. Read the documentation for your expansion card.

2. Set any necessary jumpers on your expansion card.

3. Remove your computer system’s cover.

4. Remove the bracket on the slot you intend to use. Keep the bracket for pos­sible future use.

5. Carefully align the card’s connectors and press firmly.

6. Secure the card on the slot with the screw you removed in step 4.

7. Replace the computer system’s cover.

8. Setup the BIOS if necessary
(such as “IRQ xx Used By ISA: Yes” in PNP AND PCI SETUP)

9. 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.

22 ASUS SP97-XV User’s Manual

III. INSTALLATION

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.

T o 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.

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 earlier. You 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).
