CHAPTER 2: HARDWARE INFORMATION
2.1 INSTALLING CENTRAL PROCESSING UNIT (CPU)
Special Warnings:
Remove Pin Cap before installation, and make good preservation for future
use. When the CPU is removed, cover the Pin Cap on the empty socket to
ensure pin legs won’t be damaged.
Warranty will be void if the pin protection cap is not in place to protect the
socket pin when sending this board for service.
pin cap
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
wards this black cut edge. The CPU will fit only in the correct orientation.
Step 2-1:
Step 2-2:

915P-A7 COMBO
Step 3:
Hold the CPU down firmly, and then close the lever to complete the installation.
Step 4:
Put the CPU Fan on the CPU and buckle it. Connect the CPU FAN power cable to
the JCFAN1. This completes the installation.
2.2 FAN HEADERS
These fan headers support cooling-fans built in the computer. The fan wiring and

CHAPTER 4: USEFUL HELP
4.1 AWARD BIOS BEEP CODE
Beep Sound Meaning
One long beep followed by two short
beeps
High-low siren sound CPU overheated.
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
A. BIOS Update
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.
Video card not found or video card
memory bad
System will shut down automatically.
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 boo-up to DOS prompt.
7. Type “Awdflash xxxx.bf/sn/py/r” in DOS prompt.
8. System will update BIOS automatically and restart.
9. The BIOS has been recovered and will work properly.

915P-A7 COMBO
B. CPU Overheated
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.
