BIOS dump for the Lenovo ThinkPad Edge E420, platform LLW-1, mainboard 10282-2, in a 2.18 MB RAR archive. The five-digit board number with a revision suffix follows Wistron numbering, as Wistron built this ThinkPad mainboard. Use it to recover a corrupted SPI flash with a hardware programmer. Read and back up the existing chip first, compare the board number and revision printed on the PCB with 10282-2, and check that the image size matches the chip before writing.
