BIOS archive for Compal board LA-H281P, revision 1.0, reported as working, packed in a 23.2 MB RAR. The name gives no laptop model, so identify the system from the board itself. LA- numbers are Compal's designation, and the trailing P variant matters when matching firmware. Extract the archive and review the contained images and their sizes before programming. Read and save the original SPI chip contents first. Make sure the image size matches the chip capacity, and check the PCB number.
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 @pkbiosbdv. Enginerys does not host this file.
