* The Intel Q45 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 SO-DIMM, 16 MB of memory is pre-allocated

for it at system startup. If the PC contains two SO-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.

For systems configured with more than 3 GB of memory and a 32-bit operating system, all

memory may not be available due to system resource requirements. Addressing memory above 4 GB
