Full SPI flash dump for an Asus K54LY laptop motherboard, revision 2.1, with BIOS version 202 according to the name. The 4 MB size corresponds to a 32 Mbit flash chip. Technicians use such a dump to recover boards with a corrupted BIOS that show no display or will not POST, programming it with an external programmer. Check that the board revision printed on the PCB is 2.1 and read and keep the existing chip contents before erasing, since the original may hold unique system data.
