Sapphire Radeon X1600Pro AGP BIOS for the 256MB version, archived in ZIP format. The bracketed 500810 likely indicates the clock profile used by this image. Such a ROM helps recover an AGP X1600Pro that no longer initialises after a bad flash, and can be written with ATIFlash or by programming the EEPROM off-board. AGP and PCI-E editions are not interchangeable, so confirm the bus and memory configuration of the card in hand and preserve the original BIOS dump before replacing it.
