3. IDE connectors (40-1 pin PRI_IDE [blue], SEC_IDE [black])

This connector supports the provided UltraDMA/100/66 IDE hard disk
ribbon cable. Connect the cable’s blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray
connector to the UltraDMA/100/66 slave device (hard disk drive) and
the black connector to the UltraDMA/100/66 master device. It is
recommended that you connect non-UltraDMA/100/66 devices to the
secondary IDE connector. If you install two hard disks, you must
configure the second drive as a slave device by setting its jumper
accordingly. Refer to the hard disk documentation for the jumper
settings. BIOS supports specific device bootup. You may configure two
hard disks to be both master devices with two ribbon cables – one for
the primary IDE connector and another for the secondary IDE
connector.

1. Pin 20 on each IDE connector is removed to match the covered hole
on the UltraDMA cable connector. This prevents incorrect orientation
when you connect the cables.

2. The hole near the blue connector on the UltraDMA/100/66 cable is

5.1 Managing and updating your BIOS

• The original BIOS file for this motherboard is in the support CD.

• Copy the original BIOS to a bootable floppy disk in case you
need to restore the BIOS in the future.

5.1.1 Creating a bootable floppy disk

The barebone system does not include a floppy disk drive. Connect an
external floppy disk drive (USB interface) to any of the USB 2.0 ports
on the front or rear panel if you need to use a floppy disk.

1. Do either one of the following to create a bootable floppy disk.

DOS environment

Insert a 1.44 MB floppy disk into the drive. At the DOS prompt, type:

format a: /s, then press the <Enter> key

Windows® XP environment

a. Insert a new 1.44 MB floppy disk in the floppy disk drive.
b. From the Windows desktop, click Start > My Computer.
c. In the My Computer window, click the 3 1/2 Floppy icon.
d. From the Menu bar, click File > Format.
e. Select “Create an MS-DOS Startup Disk” in the Format Options

field, then click Start.

2. Copy the original (or the latest) motherboard BIOS to the bootable
floppy disk.

Chapter 5: BIOS setup

5.1.2 Updating the BIOS

The Basic Input/Output System (BIOS) can be updated using the
AwardBIOS Flash Utility (AWDFLASH.EXE). Follow these instructions to
update the BIOS using this utility.

1. Download the latest BIOS file from the ASUS web site. Rename the file
to *.BIN and save it to a floppy disk.

2. Insert the disk that contains the new BIOS file into the floppy drive.

Save only the updated BIOS file in the floppy disk to avoid loading the
wrong BIOS file.

3. Reboot the computer.

4. Press <Alt> + <F2> during POST to display the following screen.

1001-015.BIN

5. AWDFLASH checks the new BIOS file from the floppy disk.

6. After verification, AWDFLASH flashes the new BIOS file. Do not shut
down the computer during the flash process.

1001-015.BIN

7. After the new BIOS file is copied, the computer returns to POST.

5.2 BIOS Setup program

This motherboard includes a Flash ROM that you can update using the
provided utility described in section “5.1 Managing and updating your
BIOS.”

Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you may want to
change the configuration of your computer in the future. For example, you
may want to enable the security password feature or make changes to the
power management settings. This requires you to reconfigure your system
using the BIOS Setup program so that the computer can recognize these
changes and record them in the CMOS RAM of the Flash ROM.

The Flash ROM on the motherboard stores the Setup utility. When you
start up the computer, the system provides you with the opportunity to run
this program. Press <Delete> during the Power-On Self Test (POST) to
enter the Setup utility, otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system
chassis. You can also restart by turning the system off and then back on.
Do this last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. It is
a menu-driven program, which means you can scroll through the various
sub-menus and make your selections among the predetermined choices.

Because the BIOS software is constantly being updated, the following
BIOS setup screens and descriptions are for reference purposes only,
and may not exactly match what you see on your screen.
