BIOS package for the ASUS TP500LN motherboard revision 2.0, modified to disable the soldered onboard RAM so the laptop can run from the SO-DIMM slot alone. Technicians use this kind of image when an onboard memory chip has failed and replacing BGA memory is not practical. The ZIP archive, 1.49 MB, should be unpacked and its contents written to the SPI flash with a programmer such as a CH341A. Read and save the original chip first, keep its serial and MAC data, and confirm the PCB revision matches 2.0.
