BIOS dump for the Lenovo G50-70 laptop, board number NM-A271 (platform ACLU2, built by Compal). The archive is a RAR file of about 3.2 MB, and its original file name references ACLU1 and ACLU2, so check the board number and revision on your own board before relying on it.

Read and save the original chip contents first, so you can restore them if the new write does not behave as expected.
