The following table shows which devices are affected by the various types
of resets. For details on using resets, refer to the MVME2600 Series Single
Board Computer Programmer's Reference Guide.

Endian Issues
The PowerPC processor and the VMEbus are inherently big-endian, while
the PCI bus is inherently little-endian. The following sections summarize
how the MVME2700 handles software and hardware differences in big-
and little-endian operations. For further details on endian considerations,
refer to the MVME2600 Series Single Board Computer Programmer's
Reference Guide.

Processor/Memory Domain

The MPC750 processor can operate in both big-endian and little-endian
mode. However, it always treats the external processor/memory bus as big-
endian by performing address rearrangement and reordering when
running in little-endian mode. The MPC registers in the Raven MPU/PCI
