BIOS image packed in a RAR archive for a board identified as A14CTOX, revision 2.0, with no brand given in the name. At roughly 1.14 MB compressed, the archive should contain a dump meant to be written to the board's SPI flash. Typical use is restoring a corrupted firmware with an external programmer and a test clip. Before flashing, verify that A14CTOX and REV 2.0 are printed on the PCB, read the original chip as a backup, and check that the image size equals the 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 →
