This is the guide I followed, except instead of using the Asus bios I used the MSI one to ensure compatibility with MSI Afterburner:

Here's the bootfiles I used

The Steps

Note: Make a backup of your original BIOS using GP-Z

  • Plug in the USB drive that you want to use.
  • Install and run HP USB Disk Storage Format Tool.
  • Select the USB Drive. In the "File system" drop down box, pick FAT32. Tick "Quick Format". Tick "Create a DOS startup disk, using DOS system files located at and click the "..." and direct it to the BOOTFILES folder you made.
  • Click start.
  • Once that's done, copy the ATI Flash and ASUS BIOS into the USB drive.
  • Restart your PC and boot from the USB Flash drive.
  • Once it's booted in type
  • atiflash -f -p 0 asus.rom (If you're not using crossfire)


I used the MSI one so I went: atiflash -f -p 0 MSI_R5850_unlock.A11

DOS did not like the long name so I renamed the file to something short like MSI.A11
[*]Once the flashing is done will ask you for reboot. When Windows boot you will see all your resolution lost and Windows will detect a new video card. You will have to re-install the Ati drivers again to take effect.

If you're using crossfire, I'd suggest you flash each card individually (For people like Virus). More so that I don't know how to flash more than one card at once



Good luck
