BIOS image of 16 MB for the ASUS GL503GE laptop, with the token 312 in the name most likely indicating firmware version 312. The size matches a 128 Mbit SPI flash chip, and such a full dump is normally written with an external programmer such as a CH341A when the board will not boot or the BIOS is corrupted.
