RAR archive of roughly 1.29 MB containing Intel ME System Tools for Management Engine version 3, revision r2 of the package. Such sets usually include the image-building and flashing utilities Intel supplied to OEMs for one ME generation. In repair work they help examine and reconstruct the ME portion of a BIOS image when a board fails to start or reports ME errors. Only use it on platforms whose ME firmware is actually v3; mismatched tools can produce an unusable image.
