	AH = 09h
	AL = target ID
Return: AL = status
	    FEh resident driver experienced SCSI error
	    FFh resident driver handleded event
Desc:	give any drivers chained onto INT 7D a chance to handle an exception
	  not specifically handled by the calling program
Notes:	this service exists so that resident disk servers, etc. can continue
	  running even while debuggers and profilers are active
	the resident driver assumes that a connection has been established and
	  attempts to leave the target connected
