Installation Steps

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

1. Set Jumpers on the Motherboard

2. Install System Memory Modules

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 connection, connect pins 1&2, and connect pins 2&3, respectively. A “1” is written besides pin 1 on jumpers with three pins. The jumpers will also be shown graphi-

cally such as with two pins will be shown as

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 diagrammed.

WARNING! 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.

Jumper Settings

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

The CMOS RAM is powered by the onboard button cell battery. To clear the R TC data: (1) Turn off your computer and unplug your AC power , (2) Short the two points (Labeled: CLRTC), (3) Turn on your computer, (4) Hold down <Delete> during bootup and enter BIOS setup to re-enter user preferences.

2. Keyboard Power Up (KB_UP)

This allows you to disable or enable the keyboard power up function. Set to Enable if you want to use your keyboard (by pressing <Spacebar>) to power up your computer. This feature requires an ATX power supply that can supply at least 300mA on the +5VSB lead and the new ACPI BIOS support. The default is set to Disable because not all computers have the appropriate ATX power supply. Your computer will not function if you set this to Enable and if you do not have the right ATX power supply.

3. CPU Bus Frequency (FS0, FS1, FS2)

This option tells the clock generator what frequency to send to the CPU. This allows 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).

4. CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3)

This option sets the frequency ratio between the Internal frequency of the CPU and the CPU’s External frequency. These must be set in conjunction with the

CPU Bus Frequency.

NOTES: Overclocking your processor is not recommended. It may result in a slower

speed. Voltage Regulator Output Selection (VID) is not needed for the Pentium II processor because it sends a VID signal directly to the onboard power controller.

III. INSTALLATION

2. System Memory (DIMM)

Only Dual Inline Memory Modules (DIMM) can be used with this motherboard. Sockets are available for 3.3Volt (power level) Unbuffered Synchronous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB to form a memory size between 8MB to 384MB. One side (with memory chips) of the DIMM module takes up one Row on the motherboard.

T o utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (standard 8 chips/side + 1 parity chip) and make the proper settings in the BIOS Chipset Features Setup.

IMPORT ANT: Memory speed setup is required through "Auto Configuration" in BIOS Chipset Features Setup.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Memory Modules Total Memory Socket 1 (Rows 0&1) SDRAM/EDO 8, 16, 32, 64, 128MB x1 Socket 2 (Rows 2&3) SDRAM/EDO 8, 16, 32, 64, 128MB x1 Socket 3 (Rows 4&5) SDRAM/EDO 8, 16, 32, 64, 128MB x1

III. INSTALLATION

General DIMM Notes: (not true for all memory modules)

• Four possible memory chips are supported: EDO or SDRAM with and without parity.

• SDRAM chips are generally thinner with higher pin density than EDO chips.

• BIOS shows EDO or SDRAM memory on bootup screen.

• 8 chip/side modules do not support parity, only 9 chip/side modules support parity.

• Single-sided DIMMs come in 16 or 64 MB, double-sided come in 8, 32, or 128MB.
