Introduction to ASUS SP97 Series of Motherboards

Performance

• Double the IDE Transfer Speed: ASUS SP97 series of motherboards with SiS

5582 or SiS 5598 (with VGA) improves IDE transfer rate using Bus Master
UltraDMA/33 IDE, which can handle data transfers up to 33MB/s. This new
technology is compatible with existing ATA-2 IDE specifications so there is no
need to upgrade current hard disk drives or cables.

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter busses to memory to CPU.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS SiS 5582 or SiS 5598 (with VGA) series of motherboards.
ACPI provides more Energy Saving Features for future operating systems (OS)
supporting OS Direct Power Management (OSPM) functionality. With these
features implemented in the OS, PCs can be ready around-the-clock, yet satisfy
all the energy saving standards. To fully utilize the benefits of ACPI, an ACPI­supported OS, such as the successor to Windows 95, must be used.

• PC ’97 Compliant: Both the BIOS and hardware levels of ASUS SP97 series of

motherboards meet PC ’97 compliancy. The new PC ’97 requirements for sys­tems and components are based on the following high-level goals: support for
Plug and Play compatibility and power management for configuring and man­aging all system components, and 32-bit device drivers and installation proce­dures for both Windows 95 and Windows NT.

Installation Steps

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

1. Set Jumpers on the Motherboard

2. Install DRAM Modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

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

6. Set Up the BIOS Software

1. Jumpers

Several hardware settings are made through the use of jumper caps to connect the
jumper pins on the motherboard. See layout of motherboard on page 12 for locations

(Jumpers)

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 is always on top
the keyboard connector away from you. A “1” is written beside pin 1 on jumpers
with three pins. The jumpers will also be shown graphically 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 and components, such as sound cards, con-

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

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
circuitry.

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.

3. CPU External Frequency (BUS) Selection (FS0, FS1, FS2, FS3)

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 multi­plied by the BUS Ratio equals the CPU’ s internal frequency (the advertised CPU speed).
When BUS Frequency is set to 75MHz or more, the PCI Frequency Selector
(FS3) must be set to asynchronous PCI mode to maintain PCI signal stability.

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 jumpers for CPU External (BUS) Frequency Selection.

2. System Memory (SIMM)

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 Extended Data Output (EDO) (BEDO & Parity are not supported). SIMMs
must be installed in pairs so that each Row (refer to motherboard layout 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.

IMPORTANT : Memory speed is set up through “Auto Configuration” in the BIOS
Chipset Setup of the BIOS SOFTWARE. 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 backward 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 install a fan
before you turn on your system.

T o install a processor , 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
upward 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 toward 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 only one orientation as
shown. The picture is for reference only; the CPU fan must cover the face of the
processor . W ith the added weight of the fan, no force is required to insert the proces­sor. Once the processor is 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 depending on the processor that you will install.

4. Expansion Cards

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 motherboard and expansion cards.

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

Expansion Card Installation Procedure

1. Read the documentation for your expansion card.

2. Set any necessary jumpers on your expansion card.

III. INSTALLATION

(Expansion Cards)

3. Remove your computer system’s cover.

III. INSTALLATION

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. Set up 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 a standard design there are 16 IRQs available but
most of them are already in use, leaving 6 IRQs free for expansion cards.

24 ASUS SP97 / SP97-V User’s Manual

III. INSTALLATION

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
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 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.

To simplify this process, the motherboard 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. Leave all PCI INT
assignments on “A.” PCI slot 1 automatically assigns an INT letter starting from A­B-C-D, PCI slot 2 assigns B-C-D-A, slot 3 assigns C-D-A-B, and slot 4 assigns D­A-B-C in these orders, therefore manual offsetting is not necessary.

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.

(DMA Channels)

III. INSTALLATION

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).

8. SMI Suspend Switch Lead (SMI, 2 pins)

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
