BIOS dump for a G505 laptop, most likely the Lenovo IdeaPad G505, though no brand or board number is stated in the name. The image is 4.00 MB, matching a 32 Mbit SPI flash chip. A full chip read like this can be written with an external programmer to recover a machine that no longer posts after a failed update. Check the motherboard number printed on the PCB against the source of the dump, and read the existing chip first so a backup exists.
