; Routine Description:
|
|
;
|
|
; This routine is entered as the result of a software interrupt generated
|
|
; at DISPATCH_LEVEL. Its function is to save the machine state and call
|
|
; the dispatch interrupt routine.
|
|
;
|
|
; N.B. This is a directly connected interrupt that does not use an interrupt
|
|
; object.
|
|

|
|
; Arguments:
|
|
;
|
|
; None.
|
|
;
|
|
; Return Value:
|
|
;
|
|
; None.
