Module Name:
eb164err.c
Abstract:
This module implements error handling (machine checks and error
interrupts) for the EB164 platform.
Author:
Joe Notarangelo 06-Sep-1994
Environment:
Kernel mode only.

Routine Description:
This routine is the interrupt handler for an EB164 machine check interrupt
The function calls HalpCiaReportFatalError()
Arguments:
None.
Return Value:
None. If a Fatal Error is detected the system is crashed.

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.
