You can also do the following:

Make sure you have a bootable RT volume with the DX.SYS and DL.SYS
device drivers. Make a copy of it. For the copy (and I'm assuming
it is mounted in drive 1 with the system in drive 0), issue the
following command:

        COPY/BOOT:DL DX1:RT11SJ.SYS DX1:

(or substitute the monitor filename for RT11SJ above).

What this will do is create a diskette which, when booted, will
actually boot the corresponding unit of the DL drives.

If you place this in drive 0 and boot it, the system will be
loaded and will run from DL0.
