BIOS archive labelled Dolomite, revision A, with the Management Engine region cleaned and marked as working, 16.8 MB RAR. Dolomite appears to be a board project code name; no brand or board number is given, so identify the board carefully before use. A cleaned ME region lets the firmware rebuild ME data on first boot after flashing. Write it with an SPI programmer, confirm the image matches the chip capacity, and save a read of the original chip first, since it may contain serial and network data.
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.
