Connectors

Hard Disk Connectors: IDE1 & IDE2

The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100/133
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 66/100/
133 functions. You can connect up to four hard disk drives, CD-ROM, LS­120 or other IDE devices. The included IDE power cable has two large
connectors and two small connectors. The large connectors can be used for
IDE devices such as hard disks and optical drives. One of the small
connectors can be used for IDE devices such as slim optical drives, but the
other must be connected to IDE_POWER (see page 2-6).

IDE1 IDE2

The first hard drive should always be connected to IDE1. Master and Slave
drives can be connected to both IDE connectors. You must configure the
drives to the desired mode by setting the jumper accordingly. If you install
two hard disks on a single cable, you must set the jumper on the second hard
disk drive to slave mode. Please refer to the hard disk documentation
supplied by hard disk vendor for the jumper settings.

Both IDE1 and IDE2 have a 20th pin included. The 20th pin was added to
provide extra voltage to power 40-pin Disk-on-Modules (DOM). See
Voltage Selector: J1 on page 2-17. You must use IDE cables that do not
block the 20th pin.

IMPORTANT: Before adding IDE devices, refer to Appendix C for the onboard

power specifications to figure out how many devices can be supported.

Jumpers

The mainboard provides jumpers for setting the mainboard’s functions. This
section will explain how to change settings for your mainboard’s functions
through the use of the jumpers.

Clear CMOS: CLEAR_CMOS

The onboard CMOS RAM stores system configuration data and has an
onboard battery power supply. The long-life battery has a lifetime of at least
5 years. If you want to clear the system configuration data from the CMOS
RAM, use the CLEAR_CMOS (Clear CMOS jumper). You can clear the
CMOS by shorting pins 1 and 2 while the system is off. Then return it to the
2-3 pin position. Shorting the jumper while the system is on will damage the
mainboard. The default position of the jumper is on pins 2 and 3.

Slots

Peripheral Component Interconnect: PCI

The PCI slot allows you to insert PCI expansion card. When adding or
removing expansion cards, make sure that you unplug the power supply first.
Meanwhile, read the documentation for the expansion card to make any
necessary hardware or software settings for the expansion card, such as
jumpers, switches or BIOS configuration.

PCI Interrupt Request Routing

The IRQ are hardware lines over which devices can send interrupt signals to
the microprocessor. The “PCI & LAN” IRQ pins are typically connected to
the PCI bus INT A# ~ INT D# pins as follows:

PCI Slot INT B# INT C# INT D# INT A#

WARNING: The PCI slot does not support any PCI card requiring -12V.

enter Setup without entering any password.

When a password has been set, you will be prompted to enter it every time
you try to enter Setup. This prevents an unauthorized person from changing
any part of your system configuration.

There are two types of passwords you can set. A Supervisor password and a
