BIOS dump for a Compal LA-E841P board, revision 2.0, packed in a 3.97 MB RAR archive and labelled as fully working. Compal uses the LA-xxxxP scheme for boards it builds for several laptop brands, and the name does not say which model this one went into. Extract the image and compare its size with the SPI flash chip before writing it with a programmer such as a CH341A. Always read and save the original chip contents first, and verify the PCB revision matches 2.0.
