What's the difference between RT11XM and RT11SJ? What do the last letter signify?
SJ is the Single Job monitor, which allows you to run one thing at a
time from the console.
FB is the Foreground/Background monitor, which allows you to run a
background task as well.
XM is the eXtended Monitor, which is like FB but in addition allows the
use of more than 56kB memory (by paging). Device drivers for XM have a
three-letter filename, with the third letter always being 'X'.
BL is the BaseLine monitor, which is what is on the distribution media.
It's like SJ, but includes all the devices you're likely to want to
boot from (so you can do a SYSGEN and transfer your customised monitor
to your preferred boot medium) and excludes all the frilly bits you
might want but aren't needed for a SYSGEN.

So I imagine any device drive with the X at the end is the better one to
use with the XM monitor? Or is it mandatory to use X device drivers in
the XM monitor?
BL is the BaseLine monitor, which is what is on the
distribution media.

So this brings up another question: I've noticed that I don't explicitly
need to LOAD device drivers for the devices I want to use when I boot
RT-11. In particular, I don't need to LOAD DD when I want to use the TU58
simulator. Are they found and loaded automatically when the OS boots,
or...?

From what I remember you can build the sysgen with the
drivers you know will
be there at boot time but could still load them yourself
afterwards if
needed. Must drag the micro73 down here this week and see if my RL02s are
playing nice.....

The Monitor you're using was Sysgen'd to load those drivers automatically.
You could probably free up a little memory by doing a Sysgen that just
includes the drivers you need.

Ok, so the DD.SYS file still needs to be on the disk. It just gets loaded

Jerome Fine is more suited to answering this than me, particularly since I
can't remember the full sysgen process other than to specify drivers,
declare maximum open files etc. I can only assume your system files and
kernel are already set up to load the correct disk drivers.....
