Hello, I need a bios to XFX 7770 Core Edition (FX-777A-ZNF4). Yes, I broke the first rule (didn't make a copy of the old one) and installed this bios. Unfortunately under this bios card has artifacts in DOS and after loading Windows there is only a dark blue static screen. So I need a original bios or if this bios will work? It is for 777A-ZNF10 card, but I didn't seen that card on the internet, so I suppose that "10" is a version of bios? Regards, bar1004.
