The Intel Q35 Express chipset includes a built-in Management Engine (ME), which allocates memory for manageability functions.
Management Engine memory is shared with system memory. If the PC contains a single DIMM, 16 MB of memory is pre-allocated for
it at system startup. If the PC contains two DIMMs, 32 MB of memory is pre-allocated. This memory is not made available to the
operating system, just as pre-allocated video memory is not available.
