BIOS dump for the Dell Latitude E6400 on motherboard LA-3805P, a board number in the Compal numbering style, so Compal is the ODM behind the PCB. The file has no extension and is 4 MB, consistent with a 32 Mbit flash chip. It is used to reprogram the BIOS chip when the laptop is bricked or refuses to post. Check that the LA-3805P marking and revision on your board match, and save the current chip contents before flashing with a programmer.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
