This is a tutorial on how to modify your BIOS using Radeon BIOS Editor and how to flash it using ATI Winflash.
First you need to download the following:
Radeon Bios Editor
ATI Winflash
They are both executables, so no installation is require. Unzip Winflash and we're ready to go.
Start by launching Radeon BIOS editor. Once you get into the main screen click on Acquire/Flash.
Now enter the path to Winflash. Click Analyze.
Click Acquire BIOS. You now have your current BIOS loaded into RBE, ready for editing.
*VERY IMPORTANT!*
Before you edit anything make a backup of your BIOS by clicking Save BIOS, just in case of a bad flash.
Go ahead and edit any of the values you wish. When you're done save a copy of you modified bios if you want, otherwise you're ready to flash.
*VERY IMPORTANT!*
Before you flash, make sure you close any non-essential applications, programs, etc. just to be safe.
Click Acquire/Flash. Click Flash BIOS. You will probably be prompted about the BIOS part number not matching, this is normal even with an unmodified BIOS. Click Yes. You will be prompted to restart, click Ok.
Congratulations!! You have officially flashed your BIOS. If you have any questions feel free to post them here. I plan on adding a section on how to recover from a bad flash, and how to flash in DOS in the future, as well as adding pictures.
