Hardware information

System memory

The motherboard has two Double Data Rate (DDR) DIMM sockets that sup-

ports up to 2GB non-ECC PC2700/2100 DDR..

1. Make sure the memory frequency and bus frequency setting in the

BIOS are the same or set to [Auto] ensure system stability.

2. A DDR DIMM is keyed with a notch so that it fits in only one

direction. DO NOT force a DIMM into a socket to avoid damaging

the DIMM.

Installing a DIMM

1. Unlock a DIMM socket by pressing the retaining clips outward.

2. Align a DIMM on the socket. Make sure the notches on the DIMM

exactly match the notches in the socket.

3. Firmly insert the DIMM into the socket until the retaining clips lock into

place.

*These IRQs are usually available for ISA or PCI devices.

When using PCI cards on shared slots, ensure that the drivers support

“Share IRQ” or that the cards do not need IRQ assignments.

Otherwise, conflicts will arise between the two PCI groups, making the

system unstable and the card inoperable.

Hardware information

PCI slots

There are three 32-bit PCI slots on this motherboard. The slots support

PCI cards such as a LAN card, SCSI card, USB card, and other cards that

comply with PCI specifications. The following figure shows a LAN card

installed on a PCI slot.

AGP slot

This motherboard has an Accelerated Graphics Port (AGP) slot that

supports +1.5V AGP cards. When you buy anAGP card, make sure that

you ask for one with +1.5V specification. Note the notches on the card

golden fingers to ensure that they fit the AGP slot on your motherboard.

Install only 1.5V AGP cards on this motherboard!

Jumpers

1. Clear RTC RAM ( 2-pin CLRTC1)

This jumper allows you to clear the Real Time Clock (RTC) RAM in

CMOS. You can clear the CMOS memory of date, time, and system

setup parameters by erasing the CMOS RTC RAM data. The RAM

data in CMOS, that include system setup information such as system

passwords, is powered by the onboard button cell battery.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Short the two pads to clear CMOS.

3. Plug the power cord and turn ON the computer.

4. Hold down the <F11> key during the boot process and enter BIOS

setup to re-enter data.

Except when clearing the RTC RAM, never remove the cap on J10

jumper default position. Removing the cap will cause system boot

failure!

2. Clear Password ( 2-pin J11)

This jumper allows you to clear the password in CMOS. Set to pins

(2-3) to clear the password and set to pins (1-2) for default normal

setting.
