BIOS image for the ASUS S400C / S400CA laptop, labelled as taken from the CPU board, with the token UNBORD most likely meaning onboard and SLJ8E apparently a processor sSpec code noted by whoever saved it. The 8 MB size corresponds to a 64 Mbit SPI flash chip. Technicians write such a dump with a programmer like a CH341A when the original chip is corrupted. Read and save the existing chip contents first, and confirm the board revision on the PCB matches the model before flashing anything.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
