BIOS

 

 

Overview

The BIOS (Basic Input Output System) of a mainboard is software stored on an EEPROM chip which helps the mainboard to function correctly and communicate with devices on the PCB surfaces and also secondary devices and software protocols that are attached to or running on the mainboard respectively.

Sometimes we find it necessary to update the BIOS image files in order to make allowance for newer processors, newer operating systems, enhance device compatibility, add features or increase performance and stability. To upgrade the BIOS, one has to subject their machine to the simple process of flashing.

Flashing the BIOS

There are two ways in which we recommend the end user flashes their BIOS. They will be termed as follows :

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.

Do's and Don'ts

  • DO - Flash the BIOS if it is advised that you do so by EPoX Technical Staff
  • DO - Flash the BIOS if you are confident that you will be successful and are 100% sure that you have the correct binary code
  • DON'T - Flash the BIOS if using a floppy disk if system is not able to safely read and write from floppy disk.
  • DON'T - Flash the BIOS on the recommendation of anyone other than EPoX technical staff, unless they are directed and can give proof of direction by a member of EPoX staff.
  • DON'T - Flash the BIOS assuming it will have undocumented fixes
  • DON'T flash the BIOS on a RAID enabled mainboard unless you are fully aware that changes to supplied RAID BIOS and drivers existing on boot hard drive may conflict and cause a non booting system.
  • Unsuccessful flashing of mainboard can lead to a corrupted BIOS, for which there is no warranty.

The ALT+F2 Method

  1. Download the required BIOS image file from the EPoX website.
  2. Ensure the mainboard is set at LOAD OPTIMIZED DEFAULTS and is not overclocked in any way.
  3. Copy or extract the BIOS image file (named xxxxxxxx.bin) to a blank floppy disk with no bad sectors on it.
  4. Restart the machine with the floppy disk in the floppy drive
  5. When prompted at machine initialization, press ALT+F2 to begin performing the flashing of the BIOS.
  6. The BIOS will automatically flash and reboot the machine.
  7. After this, press DEL to enter the BIOS setup and select to "LOAD OPTIMIZED DEFAULTS". After doing this select to "SAVE & EXIT"
  8. Please note that this does not create a backup of the BIOS binary file.
  9. 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 the required BIOS image file from the EPoX website.
  3. Ensure the mainboard is set at LOAD OPTIMIZED DEFAULTS and is not overclocked in any way.
  4. Copy to this floppy disk a copy of AWDFLASH.EXE and also a copy of the BIOS binary image file called xxxxxxxx.bin
  5. Insert the diskette into drive A, reboot your system and boot from the diskette.
  6. When booting is finished, type awdflash *.bin /sn/py/cc/ (dependant of the name of the BIOS image file) and then press return to run BIOS upgrade program.
  7. The BIOS will automatically flash and reboot the machine.
  8. After this, press DEL to enter the BIOS setup and select to "LOAD OPTIMIZED DEFAULTS". After doing this select to "SAVE & EXIT"
  9. Please note that this does not create a backup of the BIOS binary file.
  10. For Command line help on Award Flash utility, type AWDFLASH/? at the command prompt and press return.

Highpoint Users Beware

  1. If updating the BIOS of a mainboard with a Highpoint RAID controller, note that it is necessary to ensure that the drivers for the Highpoint Controller used within Windows are identical to that of the BIOS. It is possible that Windows will not boot if there is asynchronous pairing between Highpoint BIOS and driver version.

 

BIOS Image Files (Last updated 28/10/2004 09:37:55 +0100 )

Here you will find downloads of EPoX UK's own recommended BIOS binaries, each recommended for optimum performance, stability and compatibility with each particular mainboard. These BIOS images are all fully supported by EPoX UK, however may not be supported by other branch offices.

 

Ordering a replacement BIOS

Replacement mainboard BIOS can be ordered online at our online store which can be found HERE.

This service is available for all the mainboards shown therein on both Socket A and P4 Platforms.

It is not possible to order these components by telephone.
