So I'll make my admission of guilt short: I'm an idiot. It was late and I was deep in the instructions to modify my 6850 and unlock the shaders. I extracted BIOS backups from both my 6850 and my 5870, used a script to modify the 6850 BIOS and change the shader value (my 6850 is a non-reference, so this seemed to be the safer route). I then used a batch script that uses ATIWinFlash to flash my card. However, I forgot to modify the device number in the batch script and it flashed my 5870 instead. I realized this when I restarted and my computer would not POST (the 5870 was in slot 0).
So, I've now spent all day reading up on how to recover my card.
Here's the situation:
- I can successfully boot with the 5870 in slot 1 and my 6850 in slot 0.
- The 5870 shows up in windows as a VGA device, but outputs no video. My PC bluescreened when I tried to go into the screen resolution dialog built into windows (not catalyst control center).
- The fan on the card spins up as if it was starting normally when power is applied.
Here's what I've tried so far:
- Flashing with ATIWinFlash. It does not see the card. Only my 6850 shows up when I run with "-i"
- Booting off a USB stick into DOS and flashing with ATIFlash. Does not recognize my card when I run with "-i"
- Blind flash with ATIFlash. Booted into DOS with the 6850 in the machine only (slot 0), removed 6850 and replaced with 5870 while PC was on an at the dos command line. Ran ATIFlash command. No change, card is still not recognized. I'm certain the command was typed correctly.
- I took the cooler off my card, found the BIOS chip and shorted VCC and WP# (pins 3 and 8 according to the datasheet). ATIFlash still does not recognize the card. I'm an electrical engineer and I am confident that the soldering was done correctly.
I'm really at a loss here and I'm surprised that I've gone as far as I have with no results. Is there anything I missed or is there anything else that I can try? I just bought this card and it was working great and now all it is is a paperweight
