2.1 CENTRAL PROCESSING UNIT (CPU)
Step 1: Pull the lever sideways away from the socket and then raise the
lever up to a 90-degree angle.
Step 2: Look for the black cut edge on socket, and the white dot on CPU
should point forwards this black cut edge. The CPU will fit only
in the correct orientation.

4.2 EXTRA INFORMATION
A
A. . B BI IO OS S U Up pd da at te e
After you fail to update BIOS or BIOS is invaded by virus, the
Boot-Block function will help to restore BIOS. If the following message
is shown after boot-up the system, it means the BIOS contents are
corrupted.
In this Case, please follow the procedure below to restore the BIOS:
1. Make a bootable floppy disk.
2. Download the Flash Utility “AWDFLASH.exe” from the Biostar
website: www.biostar.com.tw
3. Confirm motherboard model and download the respectively BIOS
from Biostar website.
4. Copy “AWDFLASH.exe” and respectively BIOS into floppy disk.
5. Insert the bootable disk into floppy drive and press Enter.
6. System will boot-up to DOS prompt.
7. Type
“Awdflash xxxx.bf/sn/py/r” in DOS prompt.
(xxxx means BIOS name.)
8. System will update BIOS automatically and restart.
9. The BIOS has been recovered and will work properly.

B. . C CP PU U O Ov ve er rh he ea at te ed d
If the system shutdown automatically after power on system for
seconds, that means the CPU protection function has been activated.
When the CPU is over heated, the motherboard will shutdown
automatically to avoid a damage of the CPU, and the system may not
power on again.
In this case, please double check:
1. The CPU cooler surface is placed evenly with the CPU surface.
2. CPU fan is rotated normally.
3. CPU fan speed is fulfilling with the CPU speed.
After confirmed, please follow steps below to relief the CPU protection
function.
1. Remove the power cord from power supply for seconds.
2. Wait for seconds.
3. Plug in the power cord and boot up the system.
Or you can:
1. Clear the CMOS data.
(See “Close CMOS Header: JCMOS1” section)
2. Wait for seconds.
3. Power on the system again.

4.3 TROUBLESHOOTING
Probable Solution
1. No power to the system at all
Power light don’t illuminate, fan
inside power supply does not turn
on.
2. Indicator light on keyboard does
not turn on.
1. Make sure power cable is
securely plugged in.
2. Replace cable.
3. Contact technical support.
System inoperative. Keyboard lights
are on, power indicator lights are lit,
and hard drive is spinning.
Using even pressure on both ends of
the DIMM, press down firmly until the
module snaps into place.
System does not boot from hard disk
drive, can be booted from optical drive. 1. Check cable running from disk to disk controller board. Make sure
both ends are securely plugged
in; check the drive type in the
standard CMOS setup.
2. Backing up the hard drive is
extremely important. All hard
disks are capable of breaking
down at any time.
System only boots from optical drive.
Hard disk can be read and applications
can be used but booting from hard disk
is impossible.
1. Back up data and applications
files.
2. Reformat the hard drive.
Re-install applications and data
using backup disks.
Screen message says “Invalid
Configuration” or “CMOS Failure.” Review system’s equipment. Make sure correct information is in setup.
Cannot boot system after installing
second hard drive. 1. Set master/slave jumpers correctly.
2. Run SETUP program and select
correct drive types. Call the drive
manufacturers for compatibility
with other drives.

CHAPTER 5: WARPSPEEDER™
5.1 INTRODUCTION
[WarpSpeeder™], a new powerful control utility, features three
user-friendly functions including Overclock Manager, Overvoltage
Manager, and Hardware Monitor.
With the Overclock Manager, users can easily adjust the frequency they
prefer or they can get the best CPU performance with just one click. The
Overvoltage Manager, on the other hand, helps to power up CPU core
voltage and Memory voltage. The cool Hardware Monitor smartly indicates
the temperatures, voltage and CPU fan speed as well as the chipset
information. Also, in the About panel, you can get detail descriptions about
BIOS model and chipsets. In addition, the frequency status of CPU,
memory, AGP and PCI along with the CPU speed are synchronically
shown on our main panel.
Moreover, to protect users' computer systems if the setting is not
appropriate when testing and results in system fail or hang,
[WarpSpeeder™] technology assures the system stability by automatically
rebooting the computer and then restart to a speed that is either the
original system speed or a suitable one.
5.2 SYSTEM REQUIREMENT
OS Support: Windows 98 SE, Windows Me, Windows 2000, Windows XP
DirectX: DirectX 8.1 or above. (The Windows XP operating system
includes DirectX 8.1. If you use Windows XP, you do not need to install
DirectX 8.1.)

button.
Usage:
The following figures are just only for reference, the screen printed in
this user manual will change according to your motherboard on hand.
