I've done goofed like there's no tomorrow, I tried flashing my VTX3D 6950 to 6970 and the first time it failed. I changed the bios with the bios selector and foolishly I wanted to try again, little did I know it would screw up that bios also. Now I can't boot with my 6950 at all.
Would putting it in PCI Express 2 with my 5750 as the main driver and flashing it using AtiWinFlash work?
supposedly that is what they recommend to do in your circumstance, put it in the 2nd slot and flash it with your other card used as primary system gpu. have never done that myself, but was just reading that 2 days ago.
That is because you changed the data with the bad flash.
Found this on the link below:
If you get an error like ID mismatch or Could not erase ROM, then you'll have to do some extra work in a Windows command prompt (or DOS): Run atiwinflash -unlockrom 0 followed by atiwinflash -f -p 0 bios.bin where bios.bin is the path and filename of the HD 6970 BIOS you downloaded.
- Unpack the Winflash download onto your desktop in a folder called "winflash"
- Save the 6970 BIOS in your Winflash folder and name it unlock.bin
- Click Start Button
- Type "cmd"
- Right click the entry and select "Run as Administrator"
- Black command prompt windows opens
- Type "cd %USERPROFILE%\desktop\winflash"
- Type "atiwinflash -unlockrom 0" <-- the 0 means first adapter, if you have multiple cards, physically uninstall all but the one you want to flash
- Type "atiwinflash -f -p 0 unlock.bin"
- It should complete the flashing process with a message saying something with "verified".
I've found this guide after searching a bit. I've an issue though.
At unlockrom what number should I use? I mean I can't physically uninstall my other card since I won't be able to boot anything at all with the 6950. Should I put 2? Since 0 is the first adapter and there's another spot in the 5750 for an adapter so it would be 1 and the first one in the 6950 would therefore be 2?
