Help with Radeon 7770

Hey all,

I was having stability issues with a Diamond Radeon HD 7770, and noticed they had a BIOS update on their site... the box for my card claimed it was "double black diamond overclocked" so I assumed that my card, was the only 7770 they had listed on the site that was overclocked as such.. but apparently not. When I ran the firmware upgrade, it was successful.. but the computer refused to boot with that card afterwards.. I put an old PCI card in.. got WIndows up, and noticed the update they provided used the -f flag in atiflash, durr.. my own mistake, but is it really wise for them to use that flag with an update?

Anyhow.. I've been on the hunt for a BIOS file for this card to get it going again, but haven't had any luck.

https://www.diamondmm.com/7770pe51gdd-diamond-amd-radeon-hd-video-graphics-card.html this here is the card with the bios update available.. (i notice now that the picture of the card doesn't match)

https://www.diamondmm.com/7770pe51gv-diamond-amd-radeon-hd7770-ghz-edition-video-graphics-card.html This is the card where the picture matches the card, but it's not an overclocked edition.

All the BIOSs I've found on this site's database are 128k.. but this card seems to want a 64k.. and the BIOS I accidently flashed is also 64k..

Anyone have any suggestions? Or a link to a BIOS file I may have some luck with?

Many thanks in advance.
