BIOS image for the Sapphire Radeon X1900 GT, a 256MB PCI-E card, compressed as ZIP. The bracketed 5751200 probably encodes the core and memory frequencies programmed into it. Repair use includes recovering a card with a corrupted ROM or undoing a failed overclocking flash, by means of ATIFlash or a hardware programmer on the BIOS chip. Compare your card model, memory and PCB with the file details before writing, and keep a saved copy of the original BIOS in case a rollback is needed.
