ASUS X45U BIOS for mainboard revision 2.2, marked org, which usually indicates an original dump read from a working unit. It is a 2.08 MB RAR. Technicians write such images to the SPI flash chip with a programmer to revive boards that are dead or stuck at a black screen. Revision 2.2 differs from the 2.1 boards, so check the silkscreen before flashing. Save the existing chip contents first, and make sure the binary length matches the flash capacity so the write and verify pass cleanly.
