How do you flash a video cards bios.

[Dj_]

I was wondering how you do this, I know how to flash my motherboards bios but have no clue when it comes to G-cards.
I have tried to search but cant find anything, is it completly reversible if it doesnt work.
It should work as im trying to flash my x800xt which is @540/560 to a pe version.
Saves having to keep changing the settings in ati tool.
Thanks

Same as motherboard's bios. Pretty much. It's reversible but only if the first bios worked fine. If you bork it in the first bios flash it wont boot up for you to flash it again lol, of course.
