How to erase the BIOS on ATI graphic cards?

1. Download modified flashrom. (http://www.techpowerup.com/articles/100/images/flashrom16p.zip)
2. Download Bios from here. (http://bios.techpowerup.com/)
A little sidenote: Many people complain that they get a "file not found" error when trying to flash the bios under DOS. The problem is that DOS does not know long filenames, so all files are truncated to some funky names like Powerco~1.bin. Either use the dir command, when in DOS, to find out the short filename or rename the file to something shorter while still in Windows.
3. Use modified flashrom to flash the empty.bin (http://www.techpowerup.com/articles/100/images/empty.bin) BIOS to your video card, write "flashrom -p -f 0 empty.bin" then flash the new, "flashrom -p -f 0 xxx.xxx" Bios without rebooting. Be careful - if you don't flash a real Bios after flashing the empty Bios, your card will not work properly.
