BIOS dump for the Lenovo IdeaPad Z500 laptop, a 2 MB binary image that the name marks as OK, meaning it was reported working by whoever saved it. No board number or revision is given, so compare the motherboard markings and the SPI flash chip before use. Technicians write an image like this with a programmer such as a CH341A when a laptop fails to post after a bad update. Read and keep a backup of the original chip first, and confirm the chip capacity matches the 2 MB file size, since a mismatched image will not fit.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
