				LEND					Endian Select. If set, the MPC bus is operating in little-
									endian mode. The MPC address will be modified as

described in the When MPC Devices are Little-Endian section. When LEND is clear, the MPC bus is operating in big-endian mode, and all data to/from PCI is swapped as described in the When MPC Devices are Big-Endian section.
