Noel,
Thanks for clarification.
Mark and John,
Summarizing...The disks in the RL01 directory are 5MB, which is the RL01
disk size I believed, but if they are RL02, why would I not use "RL02" in
the simh commands?
For example the code Mark wrote with John's changes, should it not be rlo2,
not rl01?
sim> sho cpu
CPU 11/40, idle enabled, autoconfiguration enabled
64KB
sim> sh rl
RL RL11, address=17774400-17774411, vector=160, 4 units
RL0 2621KW, attached to rsxm32.rl01, on line
write enabled, RL01
RL1 2621KW, attached to excprv.rl01, on line
write enabled, RL01
RL2 2621KW, attached to mcrsrc.rl01, on line
write enabled, RL01
RL3 2621KW, attached to rlutil.rl01, on line
write enabled, RL01
sim> b rl

1. boot the baseline unmapped system as Mark showed below. Make sure your
system is configured as an 11/40.
2. type the following at the ?>? prompt
ins $boo
boo [1,54]rsx11m
this will boot up the mapped system.
3. to make this the default (after the acs command wait for a
response that the
checkpoint file is inactive):
acs sy:/blks=0
sav /wb
now you should have a bootable mapped system which you can copy to
your
physical RL02.
I plan to use PDPGUI to port the disk images to my PDP 11/40 actual
RL02(s). I have done this a number of times, built RT-11 versions that
way. Works well.
Thanks again.

I also tried an 11/40 but the SET CPU NOEIS in
Simh gave me an error
In Ersatz-11, an -11/40 without EIS works properly (i.e. it doesn't :-):
that's how I recognized his booting error! ;-)
From: John Forecast
Depending on the state of your EIS board you may
want to stay with
the
original un-mapped system - I suspect that the
baseline mapped system
will always try to use the "sob" instruction.
No matter; SOB is part of the baseline instruction set in the -11/40. The
EIS
board adds only MUL, DIV, ASH and ASHC.
