BIOS Flash Upgrades README Flashing your computer bios can be a very intimidating chore. Many users are unfamiliar with this type of activity and are apprehensive about doing things that could potentially damage or render their system inoperable. Because of these risks, we advise users to flash their bios only if the newer bios will fix a specific problem that they are having. With computer bios upgrades, newer is not always better. Despite this, updating your computer's bios is a fairly simple task. First, you need to download the AWDFLASH.EXE file from our web site. This can be found under the bios upgrade section of the tech support area at http://www.epox.com. Next, you need to download the *.bin file that is appropriate to your motherboard. Note: Some browsers may try and default this file to an *.exe extension. Make sure that it is saved as a *.bin file, as using any other file may cause your flash operation to fail. Detailed BIOS Flash instructions for Award flash utility v5.35A or higher: 1.Prepare a clean bootable floppy disk. Using the command prompt (DOS prompt) insert a blank floppy disk in your A: drive and type: FORMAT A: /S 2.Copy the Award flash utility (AWDFLASH.EXE) to the boot disk created in step 1. 3.Copy the appropriate BIOS BIN file to the boot disk created in step 1. 4.Restart your machine keeping the bootable floppy disk in the A: drive. At the command prompt (DOS prompt) type the following: AWDFLASH XXXXXXXX.BIN Replace XXXXXXXX.BIN with the actual BIOS BIN file name copied during step 3. 5.The flash utility will then execute and load the BIOS BIN file. At this point the BIOS utility will display a screen similar to the one shown below and prompt you for a file name to save. This is the name of a file the flash utility will create, to save the current BIOS which is in your system (backup). File Name to Program: (New BIOS you are about to flash) File Name to Save: (Name of file the utility will create to backup the original BIOS) 6.After the flash utility saves the original BIOS you will be prompted to continue the operation. If you wish to continue and now flash the new BIOS code into your system answer YES to the question. You will now see a status bar as the BIOS code is written. When the program finishes you will be prompted to restart the system. 7.Restart the system and enter the CMOS setup by pressing the DELETE key during the memory test. Select LOAD SETUP DEFAULTS from the bios setup menu. Select SAVE AND EXIT. Answer YES when it asks if you are sure. Known Issues: 2MB BIOS chips: Some models of EPoX motherboards now use 2MB BIOS chips as opposed to the normal 1MB variety. Athough the flash procedure above should still be followed there are some points that need to be addressed. BIOS dates which are identified as a 2MB BIOS may not be used with 1MB BIOS chips and vice-versa 1MB BIOS dates may not be used with 2MB BIOS chips. EPoX currently only employs one type of 2MB chip. This chip is the Winbond 29C020. You can use the flash utility to identify what chip is in your system. If the utility reports the flash type shown in the picture to the right then you have a 2MB chip. All other chips are 1MB. Additionally please update your flash utility to atleast version 5.35A to flash a 2MB chip. VIA based chipset motherboards: The VIA chipsets are new enough that they are not always properly detected by the flash utility. These motherboards may return an error saying that the part number is invalid. This is normal. The flash utility is very new in comparison to the motherboard and some of the changes in the bios identifier code can cause the flash utility to think that there is a mismatch. Tell it to flash anyway and it will work successfully. Possible Problems: Chip failure error reported: Bios chips are usually good for about 6 to 10 flashes. However, a number of factors may contribute to a bios chip failing. Some of these are time, static electricity, temperature, and the like. If you flash your bios and this error is reported, then it indicates that portions of the bios memory area that the utility attempted to write to were corrupted or damaged. If the board is still relatively new and is still covered by your vendor's warranty you may or may not (depending on the warranty conditions) be able to seek recourse through your original vendor.
