Some PDP-11 boot ROMs include a utility to display a memory map. This can be useful to confirm that the controller CSR address decoding has been configured correctly as desired. For example the KDJ11-D/S M7554 "MAP" command will display a memory map as shown in the example below.
The "17772150 - 17772152 DU" line indicates that the MSCP disk CSR was found at the standard address for the first MSCP controller and the "17774500 - 17774502 MU" line indicates that the TMSCP tape CSR was found at the standard address for the first TMSCP controller. In this example both the MSCP controller and the TMSCP controller were the same physical CMD CQD-200/TM controller.

To access the on-board utility halt the processor and at the ODT prompt enter the magic number "123456" at the <CSR base address + 2>, then the magic number "100" again at the <CSR base address + 2>, then begin execution at 5000.
In the example below the on-board utility is entered and used to display the list of SCSI devices attached to confirm that the CQD-200/TM correctly sees a hard drive attached at SCSI ID 0 and an Exabyte 8200 8MM tape drive attached at SCSI ID 4.

In the example below the tape CSR is selected and then the system is booted from the Exabyte 8200 at SCSI ID 4 as MU0. The boot tape in this example is a 2.11BSD installation tape. Note that the "45Boot" is a 2.11BSD bug which is corrected in patch #433 which will corrects the KDJ11-D/S identification to "53Boot". Note that there is are two other bugs affecting the use of 2.11BSD on a CMD CQD-200/TM. The first bug is that when booting from the installation tape the root filesystem restoration during "tms(0,3)" hangs. As far as I know the cause of that bug and its fix is unknown. The second bug is that if you manage to sucessfully install 2.11BSD on a hard drive attached to a CQD-200/TM using a different tape controller or via other means the MSCP rauboot bootblock does not work with the CQD-200/TM. That 2.11BSD bug is corrected in patch #441.
