Int 2F Fn FE01  U - Norton Utilities 5.0+ Tsrs - Enable                    [U]

   AX = FE01h
   DI = 4E55h ("NU")
   SI = TSR identifier (see AX=FE00h)

Return: SI = TSR reply (lowercase version of entry SI, i.e. SI OR 2020h)
   AX = status
       0002h successful (DISKMON, FILESAVE, EP)
       FE00h successful (NCACHE-x, DISKREET)

Notes: if the enable/disable calls are used on DISKMON or NCACHE-x, the status
     report generated by the programs still indicates the previous state,
     and DISKMON.INI is not updated
   apparently has no effect on DISKREET
