Gateway laptop BIOS, an Acer group brand, saved as a 4.00 MB raw binary with the identifier P5WE0120, which looks like a platform code with a version but no board number. The size corresponds to a 32 Mbit SPI flash chip. Such images are used to reflash a board with an external programmer when it fails to post. Match the code against the original firmware on the unit, check the chip capacity, and save the existing chip contents before erasing it.
