Full 8 MB flash image for the Lenovo B590 laptop, provided as a BIN file with no board number or revision in the name. The size indicates a 64 Mbit SPI chip dump that likely contains the Intel descriptor, ME and BIOS regions together. It suits recovery of a B590 that powers on without display or bricked after an update, written with a programmer like the CH341A. Several boards were used across B590 production, so compare the PCB board number, and save the original chip before writing this image.
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.
