SET DU0: UNIT=0,PART=0
SET DU1: UNIT=0,PART=1 SET DU2: UNIT=0,PART=2
SET DU3: UNIT=1,PART=0
That *does* do it, but I can't figure out where they go. I could put
it in the
STARTS.COM file that's loaded by the SJ monitor when it
kicks off, but it doesn't appear to have been done that way. Even if
I rename
STARTS.COM so it never runs, the drives are set up correctly.
Jerome Fine replies:
Once done, the SET command values are held in the
DU.SYS device driver file. You do NOT need to
do the SET commands each time. Probably not
recommended in any case.
Assuming you are booting from an RL02, then the
DU.SYS device driver my be LOADed for a bit faster
response after the first usage. In addition, I
strongly suggest you use RT11FB rather than RT11SJ
unless the added size of the RT11FB monitor has
a serious impact on the program which you run.
In addition, it would be helpful to know the full
version number of the RT-11 version which you are
using. Based on the above SET commands, it must
be at least V05.03 or RT-11 which was released
in 1985. There are certain features which later
versions of RT-11 have that you may wish to be
aware of. the RT-11 command:
SHOW CONFIG
will provide the information, as will the banner
when RT-11 first boots.
Finally, I strongly recommend against the SET
values which have been suggested since they
impact very negatively with regard to booting
RT-11. You will not lose anything with a
different combination of SET parameters, but
you will gain with respect to what drives
can be booted, in particular from a cold start.
The exact nature of which disk drives are being
used will also help. I suspect an RD53 and an
RX50, but please confirm. Most novice RT-11
users do not realize that the actual hardware
being used is very important along with the
software version.
Sincerely yours,
Jerome Fine
