Hey folks .. I downloaded https://www.guru3d.com/files-get/radeon-hd-6950-to-hd-6970-flashing-tools,4.html in an attempt to upgrade the bios in my lovely XFX HD6950 that was running soo well. Like everyone else I attempted to flash it to upgrade to an HD6970. This program said to leave the bios switch in position 2! After 3 unsuccessful attempts in bios position 1 using ATI WinFlash on its own, I decided to look here and follow the advice in this program. I did exactly as was instructed to flash the bios and a windows popped up saying post rom failure, but the command line window said the flash was successful! When I rebooted, Ive got no post now in position 2, or 1. For gods sake man, why would anyone recommend position 2 to flash these cards?? I was at my wits end trying anything, but I always had a videocard to work with when the flash didnt work. But this program on its wonderful advice took care of that. Please get rid of that damn program!
