BIOS image archive for an X55C notebook based on the X55VD mainboard revision 2.1, a numbering style used on ASUS boards, although no brand is specified in the file data. Supplied as a 3.40 MB RAR, it is meant for restoring firmware on the SPI flash chip using a programmer like a CH341A or RT809. Verify that the PCB reads X55VD rev 2.1 before writing, save the original dump in case it holds unique serial or configuration data, and confirm the image fits the chip capacity.

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 →
