BIOS image set for a B41-30 notebook on the Compal LA-C291P motherboard, carrying firmware version C5CN35WW according to the name, packed in a 3.18 MB RAR archive. LA-xxxxP is the Compal numbering style, and this board is also used for related models, so confirm the label on the actual PCB. Typical use is reprogramming the SPI BIOS chip with a programmer to recover a board stuck on a black screen. Back up the original chip first and verify the image length corresponds to the flash capacity before writing.
