BIOS and EC firmware package for a laptop mainboard labelled HLG50 with Compal board number LA-M082P, revision 1A, packed in a RAR archive of 8.68 MB. The name lists both the system BIOS image and the embedded controller firmware, so the archive should cover the SPI flash and the keyboard controller side. LA-xxxxP numbers are Compal ODM boards used by several laptop brands. Confirm the code and revision silkscreened on the PCB, read and save the original chip with a programmer first, and check the image size against the flash capacity before writing.
