I just picked up a couple of KDF11-BA CPU modules. For some reason, I
thought I remembered that the 11/23+ could boot an MFM drive (ST225)
attached to an RQDX3 controller but it doesn't look like that from
the description of the boot options on the M8189 module. Is there an
alternate boot ROM that can be installed or am I just out of luck?

well, I just formatted a couple of MFM drives (ST-225's) using an RQDX3
and an 11/23+ the other day. The cpu was an M8189.
I'm not sure the eprom's are stock, however. I didn't change them but I
think they have hand written labels on them. I'm happy to make an image
of the eprom but i think theys are standard boot prom for the 11/23+.
It certainly *wanted* to boot from the drives, but they were empty :-)
ps: i started with an RQDX2 and XXDP was *not* happy with my ST-225's.
it took me a while to figure out that the RQDX2 wants an RD5x drive,
which are hard to find. once I switched to the RQDX3 I found XXDP was
happy to format the drives.

Thanks for your response. What did you set your boot device to? My
11/23+ manual says that the only choices are:
RK05
RL01 or RL02
TU58
RX01
RX02
What would I set it to to boot off an RDxx on a RQDX3?
Thanks!

I don't have the output handy ( I can get it tomorrow) but my eproms put
the RQDX2 & RQDX3 under the "DU" device, since it's MSCP. As least
I'd
claim it was at a cocktail party (i'm 99% sure it is)
So you get a choice of (i think) 7 du devices, from du0 - du6.
I think the floppy drive is DU0 & DU1. As I recall the disk is DU2.
I think I had to play with the drive select jumper on the hard disk to
make it #2, which is abnormal for a ibm pc style drive (they only use 0
& 1). As I remember the seagate docs say something about drive select
ping 2 & 3 being unused, which is not quite true.
I think my eproms have DU first. I remember RL, TU58 & RX but I don't
recall RK05. I may just not have recognized the "device name" in dec
boot parlance.
