Hi guys,

I'm hoping you can help here.

I'm in a bit of a pickle. Flashed the bios on a graphics card and its gone wrong, the pc doesnt even post, switching to the seocnd bios works perfect.

I want to reflash the first bios option, is this possible?

Thanks
 
wasnt paying attention and grab the wrong file version, apparently the version of card i have doesnt liek the gigabyte recommended bios and thus a black screen on boot.
 
what i was hoping is that i boot off bios set to switch 2 and then once booted flip the switch back to 1 and then some how flash it??

Is that a sound theory?

I've still got my 6950 that I flashed but it's been a while plus I never had to rescue a bricked BIOS. I think you'll need winflash or ATIflash. I'm not sure if then in DOS on the working BIOS you can flash the other BIOS. If that's wrong you'll need to use the onboard graphics or another card in a second PCI-E lane if you have one. Do a search and you'll find the information but I wouldn't try what you're going to do.

ok, so if i leftthe card n the pc but changed my bios to use the onboard graphics, then use winflash to flash the card with a backup of the bios i had on there before flashing it this should work?

It's something like that yes, but please read a guide or something very relative thoroughly first as I do not want the guilt of you sitting there with a sad face if anything goes wrong :). As I've said, it's been a while since I flashed an AMD card, I can't even remember how I flashed my 680 this time round and that was only 4 months ago'ish lol. It's because I have only had to do it a few times it hasn't stuck in my memory.
 
is there any difference between the two bioses? If not i'm not stressed i'll just leave it alone and fix it another day. but would be nice to know if its possible. :D

Thanks
 
ah it appears so.

I shall see about booting off my onboard gfx. Do i need to move the card to another slot or is it fine where it is.
 
Did you back up the bios before flashing?

The black screen post is recoverable, I had this problem over and over when I was trying to find a decent 7970 bios (As I wondered if they had better memory timings etc)

However to recover I booted the machine with the working bios till I enter dos/atiflash, I then flip the switch to the corrupted bios and then flash.

If bios 2 is perfect then you can even back that up and flash it onto switch one

**Just remember to flip the switch to the corrupted bios before flashing**

I did indeed save the bios before flashing.

So get atiflash and do it from the bios.

Grand I shall try this.

Fingers crossed.

I just read you could do that but was wary of advising it as it seemed a bit raw to flip the BIOS when on but you've confirmed it. Thanks, saved me reading :).
 
do i have to boot to dos and then run atiflash?

Or can it be run from a command shell from within windows?
 
Well I always flash via atiflash with a USB pen really simple tbh, but if you flash via windows then you can flip the switch as soon as you enter windows, the bios is only needed to boot

Same principle, enter windows, flip the switch, flash -reboot and test, if it fails, flip back to switch 2 boot into windows and back to the corrupted one and try again simples :)
 
gentlemen, i thank you for your time and knowledge this issue is now resolved. lesson learnt.

Thanks you
