ATI Radeon BIOS Flash Guide
Written by Mavke

There are 2 ways on how to Flash your ATI Radeon Graphics Card BIOS and those depend on the Program that you use. Make sure you always make a Backup of your Original BIOS first!

First of all you will have to make a boot disk (http://www.bootdisk.com) and put on there atiflash.exe (v1.16) or flashrom.exe (v2.37) and also the new BIOS file you want to flash your Card with (xxxx.rom). After you created the boot disk, restart your PC with the boot disk.

- Flashing with ATIFlash (ATI) - Use ATIFlash v1.16
Standard Procedure:
1. a:atiflash -s 0 backup.rom [Enter] (to backup the Orginal BIOS)
2. a:atiflash -p 0 file.rom [Enter] (to flash your card with a new BIOS)

Non Standard Procedure:
(If you are trying to flash a bios for a different card then you will get a security warning that the bios does not match your card. If you are absolutely sure that the bios is compatible you can use the -f parameter to force flashing)
2*. a:atiflash -f -p 0 file.rom [Enter] (to flash your card with a new BIOS)

- Flashing with FlashROM (ATI) - Use FlashROM v2.37 oe v2.40
Standard Procedure:
1. a:flashrom.exe -s 0 backup.rom [Enter] (to backup the Orginal BIOS)
2. a:flashrom -p 0 file.rom [Enter] (to flash your card with a new BIOS)

Non Standard Procedure:
(If you are trying to flash a bios for a different card then you will get a security warning that the bios does not match your card. If you are absolutely sure that the bios is compatible you can use the -f parameter to force flashing)
2*. a:flashrom -f -p 0 file.rom [Enter] (to flash your card with a new BIOS)

Another way for making a Backup of the Original BIOS, which is more simple, is using the ATITool (v0.0.20) program.

- Backup with ATITool - Use ATITool v0.0.20 or v0.0.21
Standard Procedure:
1. Launch ATITool
2. Use "dump bios" Function and dump the BIOS to backup.rom (to backup the Orginal BIOS)

When you have a Backup of your Original BIOS, please also submit it on my site or mail it to This e-mail address is being protected from spam bots, you need JavaScript enabled to view it , so that I can put it in my Archive.
Try to Provide the following information :
- Brand of the Card
- Type of the Card
- Amount of Memory of the Card
- Brand of the Memory (when possible)
