Please note: Updating by ATIFlash 3.6 or newer (Dos), you can try to use ATI WinFlash, but I don't care!

I guess the Asus one.

But what do I do? And what do I need? I've never done this before, heh but I would like to get 800 core eventually! If not with the bios flash then with a pencil mod, but I don't have a DMM.
