Yes, the WQESD does the partitioning in the Hardware. Kinda handy as it
allows multiple bootable RT-11 partitions, OR multiple bootable OS's.

Whoops, manual even says that on the copy I see. I guess I literally need
my eyes checked as I read the COPY/BOOT wrong.

Ah, OK I understand, the COPY/SYS is how I've done it previously.

Now is this the same specific copy of DU.SYS? In other words should I be
booting off RL, setting the partitions, then init'ing the drives, then
copying? Or is this simply saying that DU.SYS vs. DUX.SYS will have
problems?

Based on this I gather it's not a good idea to switch between monitors once
you have the disk set up? Terrific.
