BIOS and keyboard controller (KBEC) firmware package for an Acer laptop on Compal board LA-K091P at revision 2.0, marked as fully working. Compal uses the LA-xxxxP numbering for laptops it makes for Acer, among others. The archive covers both the system BIOS flash and the EC firmware, which together control power-on, charging and keyboard functions. Flash each image to its own chip with a programmer, back up the originals first, and confirm the board number and revision before writing.
