BIOS archive for the Compal LA-C642P board, revision 1.0, with ADM80 as the project code. The uploader marks it as a working image, meaning it was reportedly flashed successfully on a real board. The RAR is 7.86 MB, so unpack it and confirm the binary size matches the SPI chip before programming. Compal LA-series numbers appear on the PCB near the edge or under the RAM slots, so check both the number and the revision there. Read and back up the existing chip contents before you write anything to it.
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.

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 →
