Step 1: Pull the lever sideways away from the socket and then raise the
lever up to a 90-degree angle.
Special Notice:
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
p

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.
Step 2-1:
Step 2-2:
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.

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.
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.
