BIOS archive for a Lenovo E49AL on Wistron board 11310-1, project LSS-1, with PCB code 4TK01.011, marked OK as reported working. Wistron boards carry a five-digit number with a revision suffix, here -1, plus a 48.xxxxx code on the PCB. Use it to restore a corrupted flash chip with an SPI programmer after checking that the printed numbers match exactly, since other revisions may need a different image. Save a full read of the existing chip before writing and verify afterwards.
