BIOS .rar 26.1 MB Shared

BIOS and EC firmware collection for Compal board LA-D704P revision 4.0. At 26.1 MB the archive likely holds several images or versions, so check its contents before choosing one. Having both the system BIOS and embedded controller firmware helps when a board has no power, will not charge or shows no display. Compal marks its boards with LA-prefixed numbers. Read and save the original flash chips with a programmer first, verify the revision on your PCB and make sure each image matches its chip size.
