BIOS image for a Lenovo M450 desktop with board code I6X0MH, based on the name, which also states a 32 MB flash size. It is contained in a 10.5 MB RAR archive. Such dumps are written to the SPI flash with a programmer like the CH341A to recover a system that will not post after a failed update or chip corruption. Always read and back up the original contents before writing, check the board marking matches I6X0MH, and confirm the chip capacity is 32 MB, 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.
