Description

The uploader marked it as tested, which is the uploader's claim and not something this catalog has verified. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Before flashing, confirm that the board number and revision on your motherboard match the file, and back up the original chip contents so you can restore them if something goes wrong.

Questions about this file

Will this BIOS work on my board?
Only if the board number and revision match: Lenovo ThinkPad T420. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
