RAR archive of about 1.6 MB for the ASUS K54C motherboard, revision 2.1, listed as BIOS or firmware. It probably contains the main BIOS image and possibly EC firmware, so extract it and identify each file by its size. Use a programmer such as CH341A to write the images to the matching SPI chips. Confirm the board revision printed on the PCB, back up the original chip contents first, and make sure every image matches its chip capacity.
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 →
