Hi Jerry,
I downloaded the 11/44 manuals from a bitsaver mirror site
to work
on my 11/44. In the process, I updated my webpages for the
/44 a lot.
Of course, nothing beats the manual, but I wrote the switch
settings
grouped together. The manual goes on describing the next
module, and
then shows a switch settings table that belongs to a
previously
discussed module. It was a bit confusing before I noticed
that ...
Regarding the message ... don't know, I haven't seen that
one.
It only tell you that the /44 is in console mode, shows the
address
of the stackpointer (and says so) and then the contents of
the SP.
Now ..., *when* it prints this message is perhaps described
in the
maintenance manual. I start guessing now. The contents of
the SP
seems to be an address in the boot PROM address range for
device #3
which should be in socket E50 ...
Look at the contents of the start addresses of the boot
PROMs to see
what's on the UBI (or pull the board and inspect visually).
If one of those boot PROMs is for a device that you have
(connected)
you can boot the /44 also with the simple start command, for
example
if you have 23-751A9 (RL) in socket E49, load a bootable
RL01 or RL02
pack in your drive and hit control-P on the console terminal
to get
the console prompt (>>>). Then enter "s
17773204" (& carriage return)
to boot from DL0: without executing CPU diagnostics. See my
UBI page.
I can boot my /44 now and it runs fine, but I have not yet
ran the
XXDP diags for the CPU ... If I stop RT-11, and use the
Start command
on the >>> prompt to boot RT-11 again, the system
hangs. However, if
I cycle power (UNLOAD the RL pack of course first!) and LOAD
the RL02
pack again, I can boot fine using the Start command ... huh?
But, as
said, I haven't run XXDP!
