Working BIOS dump packed as a RAR archive for a laptop mainboard labelled EPW50 with the Compal board number LA-G07GP, revision 1.0. The name marks the image as fully working, so it is meant for restoring a board with corrupted firmware. EPW50 is the Compal project code that precedes the LA number. Confirm the LA-G07GP marking and revision on the PCB first, read and save the original SPI chip contents with a programmer such as a CH341A, then check that the image size matches the flash chip capacity before writing it.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
