Module Name:
alcorerr.c
Abstract:

Joe Notarangelo 27-Jul-1994
Environment:
Kernel mode only.
Revision History:
Scott Lee 30-Nov-1995
Adapted from Alcor module for Mikasa EV5 (Pinnacle).

Routine Description:
This routine is given control when an hard error is acknowledged
by the CIA chipset. The routine is given the chance to
correct and dismiss the error.
Arguments:
ExceptionRecord - Supplies a pointer to the exception record generated
at the point of the exception.
ExceptionFrame - Supplies a pointer to the exception frame generated
at the point of the exception.
TrapFrame - Supplies a pointer to the trap frame generated
at the point of the exception.
Return Value:
TRUE is returned if the machine check has been handled and dismissed -
indicating that execution can continue. FALSE is return otherwise.
