BIOS image for the ASUS X55A laptop motherboard, revision 2.2, which the name marks as tested and working. Supplied as a RAR archive of around 3.4 MB. A tested dump is a good starting point when a board shows no display or fails to start after a bad flash, but it still must match the exact revision printed on the PCB. Write it to the SPI chip with an external programmer, and read and save the existing contents first so the original data remains available.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
