Combined BIOS package for the Lenovo IdeaPad S110 on board BM5138, containing the main system image plus the EC firmware, all in an 834 KB RAR. Having both files helps when keyboard, charging or power-on faults point to a corrupted embedded controller as well as the BIOS. Flash each image to its own chip or region with a suitable programmer. Confirm the BM5138 marking on the PCB, read and keep the original contents of both chips, and check that each file size matches its target.
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 @afsbiosfree. Enginerys does not host this file.
