racy, which allows other programs to better syn-

Information:
With 32-bit operating systems, the
configured MMIO size is stored in the
memory under 4 GB. There is therefore
less memory available (by the MMIO
size) on systems with 4 GB main mem-
ory.
This is not the case with 64-bit operat-
ing systems.
