BIOS package for the ASUS X55A, configuration X55A-SX193D, board revision 2.2, shipped as a 3.57 MB RAR archive. The name gives no flash chip or version number. Since ASUS reuses model names across revisions, compare the revision printed on the motherboard before use. Images like this are written with an SPI programmer to revive a board that powers on without display. Keep a dump of the original chip before erasing, and confirm that the file size matches the chip capacity, stripping any update header if needed.
