Module Name:
cbus_sw.c
Abstract:
This module defines the switch table for various C-bus platform
architectures under Windows NT. During initialization, the
Corollary HAL will revector all hardware-specific actions
through the switch table declared here.

Routine Description:
recognize which type of C-bus multiprocessor system it is:
C-bus I Symmetric XM
C-bus II:
Use CbusGlobal to determine which type of machine this is.
note the ordering of the platform recognition is important for future
expansion.
Arguments:
None.
Return Value:
TRUE if this Corollary MP machine is supported by this MP HAL.
FALSE if not.
