I was playing with my 9100 bios using AtiFlash.exe and the Ati Bios editor, and I backed up my bios etc before playing. When I rebooted, the machine won't POST becuase the Radeon bios must be blank (bios wipe okay, bios flash from disk gave error)

So I thought Aha! Just insert backup floppy with Autoexec AtiFlash.

But no, machine didn't boot that far :'(
I've regressed to my gf2 again, but is there any way I can restore the original bios I have on disk? it's a Sapphire R9100 atlantis 128MB at 250/400 and I DON'T have a spare PCI card. Is that the only way to even attempt to fix this?

Anyway. I've heard that Sapphire 9500 bios's are LOCKED. Does this meant that mine might have been locked too, and the bios was wipeable but not writable? Anyone who can tell me how to turn my lifeless radeon into a working one might win a prize ;)

Or maybe not. I'm skint, which is why I have a 9100, and not a 9700 :P

If you wasn't able to flash that modified BIOS the first time, then you need a different flashtool. The flashtool you are using, cannot program the EEPROM Chip (Flashrom) on your card, even if you feed the original BIOS to it.

Maybe that boot floppy would work, if you would try a different flashtool.
Here is one that might work: http://www.omegacorner.com/bios/gigabyte_flash.cab

There is also flashrom-1.3 if that one above does not work, but I dont have a link right now. Use google or search this forum.

If you cannot boot from floppy, maybe you can change a BIOS option "halt on error" or something with another AGP graphic card before trying again. I know this is necessary on some machines to be able to boot wihtout any graphic card (just using a serial terminal or similar).

Thanks Tom.

I changed the bios to Halt on error: none
Then I tried to re-flash using the original backup disk.
That didn't work, but I downloaded Flashrom and used that instead of ATIflash.

Everything's okay now :)
