CHAPTER 2: HARDWARE INSTALLATION
2.1 INSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
90
Step 2: Look for the cut edge on socket, and the gold triangle on CPU
should point forwards this cut edge. The CPU will fit only in the
correct orientation.
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

2.4 CONNECTORS AND SLOTS
FDD1: Floppy Disk Connector
The motherboard provides a standard floppy disk connector that
supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.
This connector supports the provided floppy drive ribbon cables.
IDE1/IDE2: Hard Disk Connectors
The motherboard has a 32-bit Enhanced PCI IDE Controller that
provides PIO Mode 0~4, Bus Master, and Ultra DMA 33/66/100/133
functionality. It has two HDD connectors IDE1 (primary) and IDE2
(secondary).
The IDE connectors can connect a master and a slave drive, so
you can connect up to four hard disk drives. The first hard drive
should always be connected to IDE1.

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 boot-up to DOS prompt.
7. Type “Awdflash xxxx.b f/sn/py/r” in DOS prompt.
(xxxx means BIOS name.)
8. System will update BIOS automaticall y and restart.
9. The BIOS has been recovered and will work properly.
17
K8T800-A7A
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.
