BIOS firmware packed as a 639 KB RAR archive, labelled for the M8400T with the IS7XM board and Q77 chipset, which corresponds to a Lenovo ThinkCentre desktop of the Intel 7-series generation. The name does not say whether ME is cleaned or which flash chip it targets, so check the files inside. Such images are written to the SPI flash with a hardware programmer when the machine fails to POST. Back up the existing chip first and verify the file size fits the chip.
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.
