3. HARDWARE SETUP

3.3 Hardware Setup Procedure

NOTE: The following procedure assumes that you have already installed the motherboards in an appropriate housing or case.

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

1. Check Motherboard Settings

2. Install Memory Modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

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

3.4 Motherboard Settings

This section explains in detail how to change your motherboard’s function settings through the use of switches and/or jumpers.

W ARNING! Computer motherboards and expansion 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.

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.

3. H/W SETUP

Motherboard Settings

ASUS SP98-N User’s Manual 15

Using Your Own VGA Card on the PCI Expansion Slot

The motherboard’ s BIOS will autodetect whether a VGA card is installed on the PCI expansion slot and disable or enable the onboard VGA but most operating systems bypasses the BIOS and installs the onboard VGA through Plug and Play. The following VGA Selection jumpers are not required under standard configurations but if you experience any conflicts, follow the jumper settings below.

1. VGA Selection (VGA_SEL, VGA_SEL1)

These jumpers allow you to turn the onboard VGA on or off. BIOS has automatic Enable/Disable onboard VGA. You need to disable the onboard VGA only if you have conflicts within your operating system.

3. 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.

4. CPU External Clock (BUS) (FS0, FS1, FS2) and PCI Fr equency Selection (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).

3.5 System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). S ockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac- cess Memory (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 takes up one row on the motherboard.

The SiS chipset does not support ECC. However, ECC memory modules may still be used, but the ECC function will not be available.

IMPORTANT: Memory speed setup is required through “Auto Configuration”

in BIOS Chipset Features Setup.

3.6 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 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 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.

IMPORT ANT: You must set jumpers for “CPU to BUS Frequency Ratio” and

jumpers for “BUS Frequency Selection” depending on the CPU that you install.

CAUTION! Be careful not to scrape the motherboard when mounting a clamp-

style processor fan or else damage may occur to the motherboard.

3.7. 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.

3.7.1 Expansion Card Installation Procedure:

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.

3.7.2 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 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.

3. H/W SETUP

Expansion Cards

ASUS SP98-N User’s Manual 25

3. HARDWARE SETUP

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.

Expansion Cards

3. H/W SETUP

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.

3.7.3 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).

3.7.4 ISA Cards and Hardware Monitor

The onboard hardware monitor uses the address 290H-297H so legacy ISA cards must not use this address or else conflicts will occur.

3.8 External Connectors

WARNING! Some pins are used for connectors or power sources. These are

clearly distinguished from jumpers in 3.1 Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe to

Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives. Check the connectors before installation because there may be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

1) Chassis & CPU Fan Connectors (3-pin CHASIS_, CPU_FAN)

These connectors support cooling fans of 500mA (6 Watts) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan’ s plug to the board taking into consideration the polarity of the connector . NOTE: The “Rotation” signal is to be used only

by a specially designed fan with rotation signal.

WARNING! The CPU and/or motherboard will overheat if there is no airflow

across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers,

do not place jumper caps over these pins.
