Firmware for the Lenovo CIH61MI desktop board, revision V1.1, labelled as the 4 MB build and delivered as a 2.97 MB RAR. It is the counterpart to an 8 MB version, so select it only when the board carries a 4 MB (32 Mbit) SPI flash, since an image that does not match the chip size will not program correctly. Technicians use such a file to restore a board that will not post after corruption or a failed update. Check the chip marking first, dump the existing contents as a backup, and verify after writing.
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.
