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.
