BIOS package for Compal boards LA-A901P revision 1.0 and LA-A903P, an 8.37 MB RAR archive reported as working. The two numbers suggest the firmware applies to related board variants, though the archive contents should be checked to see which image belongs to which board. Extract it, compare the image size with the SPI chip capacity, and back up the original chip before programming. Confirm the exact board number on the PCB, since sister boards may still need different files.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
