Main BIOS dump for a B560 laptop board fitted with an NVIDIA N11M-GE2-S-B1 graphics chip and Intel HM55 chipset, reported as working. The 4 MB file matches a 32 Mbit SPI flash and is the companion to a 128 KB small-chip image for the same board. Technicians write it with a programmer such as CH341A or RT809H to bring back a board with corrupted firmware. Make sure the GPU and chipset on your board match, back up the existing chip, and verify after programming.
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.
