Asus X451CA=8=X451CA Rev 2.1

BIOS .zip 3.40 MB Shared

BIOS package for the ASUS X451CA laptop built on the X451CA mainboard, revision 2.1, stored as a 3.40 MB ZIP archive. Extract it to find the flash image, then compare its size with the SPI chip on the board before programming. Technicians use such dumps to recover units that fail to POST or hang on a black screen after a bad update. Check that revision 2.1 is printed on the PCB, read and keep the original chip contents, and verify the written data afterwards.
