BIOS firmware package for a Compal LA-C811P motherboard, revision 1.0, carrying the ABQ52 project code, packed as a 3.51 MB RAR archive. Extract it first and see whether it holds a full SPI image, an EC binary or both. LA-xxxxP is Compal's board-numbering pattern, and the code and revision silkscreened on the PCB should match before you write anything. Read and save the original chip contents with a programmer such as a CH341A, and confirm the image size equals the flash 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.
