Flashed Wrong Video Bios X600XT :-( Hi all! I installed a new video card yesterday (Sapphire X800GTO Fireblade 256Mb) and decided to flash other bios versions on my old one to see if they could remove the overclocking problems I had with it. Quite dumb isn´t it? - I could have sold it for about 50€ My old card is an PCI-E Club3D X600 XT 128Mb an has 2.8ns Hynix rams. First I made a backup of the default bios with Rabit bios editor. Then I downloaded the ATI X600 XT 128 MB Hynix 2.8ns (503/368MHz) bios from the ATI Bios Collection. I checked the downloaded bios with Rabit for differences and found them to be very similar. I flashed it into the bios with Flashrom and rebooted. The card worked a little bit slower afterwards so I decided to try the Asus X600 XT 128Mb Hynix 2.2ns from ATI Bios Collection (503/370MHz). Before flashing I checked the bios for differences from the default. All timings were the same so I thought the 0.6ns difference in Ram speed wouldn´t hurt the card. The only difference I found was: There was: Active TV type: 'NTSC' > Multimedia table: at 0x6EF, Rev.1 > Hardware table: at 0x6DD, Rev.2 instead of only (Default bios): Active TV type: 'NTSC' > Hardware table: at 0x69D, Rev.2 However I flashed it into the bios (without any error message) and rebooted. No picture. I installed a PCI video card and tried flashing the old bios back. But Flashrom does not find the card anymore. I installed my new PCI-E card to see if Flashrom would detect it and it did. I read a lot about flashing before and nearly all say that it is possible to flash back an old bios with a PCI video card installed. But no one said anything about cards not found anymore afterwards. So what should i try next?
