BIOS dump in .rom format, 4.00 MB, labelled for the Sony VAIO VPCSA4C5E notebook. The name gives no motherboard number or revision, so check the board marking before use. A 4 MB image matches a 32 Mbit SPI flash chip. A technician would write it with a hardware programmer to revive a board with corrupted firmware. Keep a backup of the original chip, because dumps from another unit can carry different serial or configuration data that you may want to preserve.
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 @bios_laptop. Enginerys does not host this file.
