Firmware dump for the Lenovo IdeaPad Y550 on Compal motherboard LA-4602P, packed in a 1.30 MB RAR archive. The name gives no BIOS version or flash chip type, so extract it and compare the image size with the chip fitted on the board. Compal uses the LA-xxxxP code for its laptop boards, and that code should match the silkscreen. It is mainly useful for recovering a board with corrupted BIOS by writing it with an SPI programmer, after reading and keeping a copy of the original contents.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
