I have some cards here I want to build a PDP11 from,
at the current
that's something around an KDF11-A CPU (22bit).
Currently I have problems with some Dilog Controller, this is an DQ614
that emulates 4 RL02 Drivers out of two 20MB MFM disks (Microcience HH725).
I can install and successfully boot RT11SB.SYS and RT11FB.SYS but not
RT11XM oder RT11XB. XXDP2.5 is working fine.
Nowhere in the Dilog Documentation is something mentioned about 18 or 16
bit addressing limitations of that controller, the pinout clearly has 22
bits.
(http://www.bitsavers.org/pdf/dilog/)
I have an RQDX3 with 2 TEAC FD55-GFR-184 Floppies on this system too, I
can boot RT11XM oder RT11XB (same files!) from there fine...
If I try that from DL0 or DL1 I'll always get a trap to the ODT (0002),
regardless if I use the Dilogs own Bootloader or that from an 11/53 or an
11/73 CPU.
Which version RT11XM?
If you boot RT11XM from the RQDX3, can you read/write (as a data disk) from DQ614 DL: ?

Yes. This works flawlessly.
I first tought, that the loader from the DQ614 doesn't support 22 Bits, but
the 11/53 or the 11/73 I've got lately have their own bootroms that are
supporting RL02s. The same Problem with them..

If it works when booting from the DU controller but not the DL
controller, isn't there some COPY/BOOT command you need to issue when
you copy the RT11XM or RT11XB to the DL controller disk to install the
correct boot loader? Did you already do that the same way as when you
successfully got it to boot RT11SB.SYS and RT11FB.SYS from the DL
controller? I forget the correct syntax for that command without
looking it up.

COPY/BOOT:dd DL0:RT11xx.SYS ddn:
Where:
dd = device name (DL, DU..)
n = device number to write to
xx = RT11 monitor name (SJ, XM..)

Yes. copy/boot rt11xb.sys dl0: for example. Same command for rt11fb ans
rt11xb or rt11xm...
