BIOS dump for the Lenovo B590 laptop, which the file name marks as tested and working. The 3.17 MB rar archive does not state the board number, the flash chip or the revision, so identify the motherboard yourself before using it. Typical use is reprogramming a corrupted SPI BIOS chip with an external programmer when the notebook powers on without picture or loops on start. Save the original chip contents first so serials and settings can be recovered, and make sure the image size equals the chip capacity.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
