Today I faced a bad BIOS flash myself and now my machine is running perfectly. Let me share my experience.
I flashed an ASUS BIOS in my Sapphire Radeon HD6770 and after reboot, the card went dead(won't even post).
Things you will need- Motherboard with onboard VGA and/or 2 PCIE x16 slots and a spare graphics card(working)
What I did.
1. I unplugged my graphics card.
2. Cleared the CMOS(my onboard adapter was disabled in BIOS)- Enabled it.
3. Set the primary video adapter to IGP.
4. Turned off power and plugged my graphics card again.
5. System POST ok. Booted to Windows from onboard VGA.
6. Opened Radeon BIOS editor and flashed back my card to factory BIOS.
7. Enabled PCIE GFX in BIOS again.
8. Presto it worked. :)

Now I am very much sure you can do the same thing with a motherboard which has 2 PCIE slots. Just plug in your working card in the first slot and the bricked card in the second. Boot the system and then follow the above steps. Of course your BIOS must be set to boot from the working card(that slot).
I hope this helps. Cheers. :toast:
