BIOS .rar 3.43 MB Shared

Firmware for the Lenovo S410 on the Compal LA-A321P board, listing M40-70 and the AMD graphics part 216-0856050 in the name, which marks the discrete GPU variant, plus a trailing 4 of unclear meaning. The LA- number follows Compal's scheme. Use the dump to reprogram the BIOS chip with an SPI programmer when the system fails to boot. Verify the board number and GPU fitted, read and save the original chip and confirm the file size equals the flash capacity.
