Working BIOS image for the Lenovo IH81M motherboard, version 1.0, compressed into a 6.24 MB RAR archive; the name states it works 100 percent. It is intended for recovering a board with a corrupted or wiped SPI flash. Unpack it, identify the flash chip on the board, save a backup of its current contents with an external programmer, and only then write and verify the image. The image size must match the chip capacity, otherwise it will not fit. Confirm the board is an IH81M before use.
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.
