HD6950 - bios flash bricked it :-( - Page 2

Nope, left it overnight, nothing. If I bought a cheap PCI card, would I have any problem setting it as the primary over the pcie slot?

Try blind flashing and manually typing in the commands.

Wait a few minutes before rebooting.

If it doesn't work, try typing atiflash -unlock rom 0 and then the commands again.

if your mobo has another pcie slot, you don't need a pci card. that was oldskool when we only had 1 pcie slot.

Having zero luck blind flashing, even with unlock rom commands. As I stated in my initial post, I only have 1 PCIe slot. I have an old motherboard with two, but my PSU isn't capable of powering both my cards (not enough 6pin plugs, and I don't have an extra 4 4pin plugs to use adapters on). If buying a cheap PCI card would work, I'd rather do that than go through replacing my PSU, and swapping in my old motherboard.

I don't have a second PCIe slot to fit my old card in and I don't have onboard graphics. I've tried "blind flashing" by formatting a USB stick into a DOS boot disk, with atiflash onboard, with my backed up, original bios (as a rom file), with "atiflash -f -p 0 bios.rom" as my autoexec.bat command, with no result.

Any further tips or tricks, or anything I may have overlooked in this process would be appreciated.

PS: My card doesn't appear to have a BIOS switch on it. Oddly, it has a 1 and 2 on the board, where the switch should be, but nothing physically there on further inspection.

Your could try going to hxxp.wwwTechPowerUp.com and go to there GPU Database and grab the stock flash for you card.
When I flash my 465 to a 470 that were I grab the correct 470
update for the manufacture of my card.

Yeah, I've tried numerous bioses from there, they don't seem to have the specific bios for my non-reference model, though I do have my initial bios saved. I'm not even sure the flashing process is happening correctly - I can't see. I've tried booting and running atiflash with my old graphics card in, and it runs correctly until i get "adapter not found", which, I'm presuming, is the result of there being no ATI card onboard. How far it progresses with my HD6950 plugged in, I have no idea.

As an update, I discovered I could make a log of DOS' output, and have found out that atiflash won't detect my card. So far, every command I've tried, including "atiflash -i" has came back with "Adapter not found".

I know XFX covers overclocking for RMA. I'm not sure about flashing bios though.

There's gotta be a cheap way to fix this. The card is still good (presumably). Just needs a new bios. Let us know how it goes with xfx support.

So I bought a cheap PCI card to use, with no luck. Atiflash in DOS simply tells me "rom not erased", though it detects the card. Atiwinflash, in windows, gives me a subsystemID mismatch, and running it through command prompt, with the unlockrom command, simply causes the "flashing" progress bar to appear for a split second, then disappear without so much as an error or any kind of message.

Is my card dead? :-(

For what it's worth, I've had all of those happen in the process of flashing my card to an unlocked bios, but it didn't kill the card. The card(s) (actually both of them gave me that response) were fine, even though ATIwinflash was a pain and I never had positive confirmation of a flash, just flashing screens on my HIS card, and the XFX card my computer crashed and rebooted, and then when I ran GPU-Z the next time, it was identified as correct. I guess you're not getting that far though, can't get any display. Stupid question but have you checked all connections twice?

This is why I always tell people there are definitely risks to flashing (especially with non-reference, and ESPECIALLY with no backup switch), and often it's not worth the gain.... Sorry you had to be the lesson.
