Generic BIOS image tagged for Lenovo, but the file name gives no model, board number or version, so its origin cannot be confirmed from the name alone. The 8 MB size suggests it targets a 64 Mbit SPI flash chip. Treat it with caution: open it in a hex editor or UEFI tool to look for model strings, compare it against your own chip dump, and keep an untouched backup of the original contents before programming. Writing an unmatched image can leave a board dead or without its serial and keys.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
