To install thesystem withan add-onAGP VGA card, please make sure
toinstall the driverof add-on AGPVGA card before onboard VGAdriver
installation. If the onboardVGA driverhasalreadybeeninstalled before
you install the add-on AGPVGA card,thesystem will automatically set
theonboard VGA asthe primary graphicsadapter.
For the onboard VGAdriver can’tberemoved completely,and to solve
thisproblem, please followthestepsbelow,
1. Disable onboardVGA utility under the operating system,and reboot
PC. After PC restarts, the system will automatically set theAGP
VGA card asthe graphicsadapter.
2. Or, re-install your operating system toensure theAGPVGA card

4.1 AWARDBIOS BEEP CODE
Beep Sound Meaning
One long beep followed by two short
beeps Video card not found orvideo card memory bad
High-low siren sound CPU overheated
System will shut down automatically
One Short beep when system boot-up No error found during POST
Long beeps every other second No DRAM detected or install
4.2 EXTRA INFORMATION
AA..BBIIOOSSUUppddaattee
After you fail to update BIOS or BIOS isinvaded by virus, the
Boot-Blockfunction will help torestore BIOS. If the followingmessage
isshown after boot-up the system,itmeansthe BIOS contentsare
corrupted.
In thisCase, please follow the procedurebelow torestore the BIOS:
1. Make abootablefloppy disk.
2. Download the Flash Utility“AWDFLASH.exe” from the Biostar
website:www.biostar.com.tw
3. Confirm motherboard model and download the respectivelyBIOS
from Biostar website.
4. Copy “AWDFLASH.exe”and respectivelyBIOS into floppydisk.
5. Insert thebootablediskinto floppydrive andpressEnter.
6. System will boot-up to DOS prompt.
7. Type“Awdflash xxxx.bf/sn/py/r”in DOS prompt.
(xxxx meansBIOSname.)
8. System will update BIOS automatically and restart.
9. The BIOS has been recovered and will work properly.

If the system shutdownautomatically afterpoweron system for
seconds, that meansthe CPUprotectionfunction hasbeen activated.
When the CPU isoverheated, the motherboard will shutdown
automatically to avoid a damage ofthe CPU,and the system maynot
power on again.
In thiscase, please double check:
1. The CPU cooler surfaceisplacedevenlywith the CPU surface.
2. CPU fan is rotated normally.
3. CPU fan speed isfulfilling withthe CPU speed.
Afterconfirmed, please follow stepsbelow torelief theCPU protection
function.
1. Remove the power cord from power supplyfor seconds.
2. Wait for seconds.
3. Plug in the power cord andboot up the system.
Or you can:
1. CleartheCMOS data.
(See “Close CMOSHeader: 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 bootedfrom optical drive. 1. Check cable running from disk to disk controller board. Make sure
both ends are securely plugged
in; check the driv e 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 bootsfrom 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.” Reviewsystem’s equipment. Make sur
e
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
manufacturersfor compatibility
with other drives.
