Hi, Fixing a completely gone wrong ATI BIOS flash. The other day I was trying to recover a Radeon 4890 which was flashed with the wrong BIOS. To do that I put an 5970 (first card I had handy) into the primary PCI-E slot and the 4890 into the secondary slot. As always I was in a hurry so I ran: atiflash -f -newbios -p 0 4890.bin Heart Attack!! Realize what just happened? The 0 stands for adapter 0 which is the PRIMARY card, so my 5970 now had an 4890 BIOS on it. So I thought, I'll just flash it back... Problem: the 5970 PCI device ID changed. ATI's flashing programs query the device ID to know which GPU to expect, so the software can use the right flashing method. Unfortunately a device with wrond ID doesn't exist at all so ATIFlash didn't even show the card as installed. The only way I could imagine how to fix this is by disconnecting the flash memory somehow so that the device ID does not get changed (all ATI GPUs have a default value which can be overwritten by the ROM.) So i had to find those serial flashmemory ROMS from my card. I found two ROMS (serial flashmemory) and they are Pm25LV010, AE1011, M19926LG and Pm25LV010, AE1011, M19927LG. I try connect 1 and 8 pin together from those ROMS, but that didn´t had luck. I got same error from ATIflash --> no adapter. I complete fixing my 4890. I connect flashmemory 1 and 8 pin together and WOLAA, when restarting computer ATIflash found my 4890 in adapter. So, i think the problem is now something with connects those two flashmemorys together, or something like that. Please help me recover my 5970, THANKS.
