!!!WARNING!!!
Never attempt to Flash your BIOS from a hard disk, DOS Window, DOS 
shell, or in Windows NT. If your system is working without problems 
or conflicts, then it is not recommended that you flash your BIOS. 
Improper flashing procedures may result in a dead system! Follow the 
these instructions carefully.
Files included in this download:
README.TXT	Text file with BIOS Release & Application Notes.
UPDATE.BAT	Batch file for the Flash BIOS update process.
RESTORE.BAT	Batch file for the Flash BIOS restore process.
xxxxxxxx.BIN	BIOS binary file used by UPDATE.BAT.
AWDFLASH.EXE	Program used to Flash BIOS code to the EEPROM.
Enhancements & Fixes for this beta BIOS release:
1. Added Speical I/O and USB park mode item.
2. Fixed boot block code overwrite.
3. Added 'DRAM Bank Interleaving' and 'Burst Length' item.

BIOS Update Instructions
There are two ways in which we recommend to flash the BIOS. 
They will be termed as follows:
. The ALT+F2 Method 
. The Boot Disk Method 
The ALT+F2 method may not be available on older mainboards with older 
BIOS, in such cases it is necessary to carry out the Boot Disk Method.
----------------------------------------------------------------------
The ALT+F2 Method
1. Download the required BIOS image file from the EPoX website. 
2. Copy or extract the BIOS image file (named xxxxxxxx.bin) to a blank
floppy disk with no bad sectors on it.
3. Restart the machine with the floppy disk in the floppy drive 
When prompted at machine initialization, press ALT+F2 to begin 
performing the flashing of the BIOS. 
4. The BIOS will automatically flash and reboot the machine. 
5. After this, press DEL to enter the BIOS setup and select to "LOAD
OPTIMIZED DEFAULTS". After doing this select to "SAVE & EXIT."
6. Please note that this does not create a backup of the BIOS binary file. 
7. This does not require you to have a bootable floppy disk. 
----------------------------------------------------------------------
The Boot Disk Method
1. Create a bootable floppy disk in accordance with the instructions 
laid out in the manual of your particular operating system. This 
bootable floppy needs to be able to boot to a DOS console capable of
executing normal MS-DOS batch and executable files.
2. Download and extract the xxxxxxxx.EXE file corresponding to your 
model from the EPoX website to the floppy. It will self extract into 
the above listed files.
3. Boot using your DOS floppy disk to the ?A:\>? command prompt. At the 
DOS command prompt type: UPDATE
4. The BIOS will automatically flash.
5. Reboot the machine. 
6. After this, press DEL to enter the BIOS setup and select to "LOAD
OPTIMIZED DEFAULTS". After doing this select to "SAVE & EXIT."
Note: During the use of UPDATE a backup of your original BIOS 
date/code will be saved in the same directory as the UPDATE file. It 
will be called ?OLD.BIN? and can be used with the restore 
instructions below in case you need to revert back to the original 
BIOS date/code.
----------------------------------------------------------------------
BIOS Restore Instructions
Use of the restore procedure requires the OLD.BIN file created in the 
Boot Disk method procedure above! 
1. Boot using your DOS floppy disk to the ?A:\>? command prompt. At 
the DOS command prompt type: RESTORE
2. The BIOS will automatically flash.
3. Reboot the machine. 
4. After this, press DEL to enter the BIOS setup and select to "LOAD
OPTIMIZED DEFAULTS". After doing this select to "SAVE & EXIT." 
5. The system flash is now completed and should now be reverted back 
to the original BIOS date/code.
----------------------------------------------------------------------
BIOS flash failed
If you have access to an old un-accelerated ISA video card, you might 
be able to recover your BIOS. Remove all cards and drives from your 
system, except for the ISA video card and the floppy drive. Then try 
to boot from a system disk (a bootable floppy with only the flash 
programs and corresponding BIOS binary). If you are able to boot to 
the floppy, flash your BIOS according to the directions above. 
----------------------------------------------------------------------
I get out of memory errors when I flash my BIOS! 
On some system configurations, even with a clean boot disk, you will 
get an out of memory error (insufficient memory) when you try to 
flash your BIOS. The solution is simple: Try bypassing the startup 
files by pressing the following keys during startup using you 
bootable floppy disk. Attempt the FLASH again.
DOS 6.2x boot disks - press F5 to bypass. 
WINDOWS 95/98 boot disks - press F8 and select "Safe command prompt." 
Lastly try using a MS-DOS 6.x boot disk. 
----------------------------------------------------------------------
Manual use of the AWDFLASH Utility
Most users will find that our UPDATE and RESTORE batch files can 
accomplish the BIOS flash with the majority of configurations. But if 
you wish to manually use the AWDFLASH utility, below are the most 
common command line usages and parameters.
