BIOS and EC firmware package for board HH5A4 on Compal LA-M211P, in a 7.53 MB RAR archive. With both images included, you can reprogram the main SPI BIOS chip and the embedded controller firmware, which handles power sequencing, the keyboard and battery charging. LA- numbers with a P suffix follow Compal's ODM pattern. No laptop brand or revision is given, so match the PCB label carefully. Read the original chips first and confirm that each image size fits its target flash.
