Hi -
From: Jochen Kunz <jkunz(a)unixag-kl.fh-kl.de>
I am preparing my PDP-11/73 for my exhibition at the VCFe. I want to get
the DHV11 (M3104) and a four port DLV11J clone to work. At the moment I
get upon boot:
autoconfig: warning: more than three handlers for device cn on line 38.
That is not a normal message. I believe autoconfig is saying that
is something wrong with line 38 of /etc/dtab
dhv ? csr 160440 vector 310 didn't interrupt.
ra 0 csr 172150 vector 154 vectorset attached
ra 1 csr 160334 vector 764 vectorset attached
rx ? csr 177170 vector 264 skipped: No CSR.
tms 0 csr 174500 vector 260 vectorset attached
ts 0 csr 172520 vector 224 attached
cn 1 csr 176540 vector 344 no address found for kl/dl-11
What is wrong with the "cn" devices?
Is 'cn 1 ...' line 38 of the /etc/dtab file?
Did you compile a kernel with NKL set to 5 (1 for the console and
4 for the DLV11J)?
Cheers,
Steven Schultz

# NKL includes both KL11's and DL11's.
NKL 4 # KL11, DL11
The card has four ports, one of them is the console. (The M8192 CPU card
has no SLU / ROM / ...)
But I would prefere to get the DHV11 working. It seams that this device
is more suitable for multi user operation.
BTW: Never play with the SMD cables when the machine is running. Now I
get:
# fsck
** /dev/ra0a
File System: /
** Last Mounted on /
** Root file system
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Free List
BLK(S) MISSING
SALVAGE? y
** Phase 6 - Salvage Free List
1364 files, 11625 used, 2430 free
***** FILE SYSTEM WAS MODIFIED *****
But on the next reboot I get the same when running fsck. Any hints?

I didn't see my other post go through; have you tried adding some comments
to the end of this line? Perhaps the autoconfig parser becomes confused
if there aren't any.

Mine is at least correctly identified by autoconfig, though I've never
attached a terminal to it to see whether the ports actually do anything.
The post that's vanished included my dhv line from /etc/dtab but, except
for the goofy CSR I used for some reason that I cannot now remember, it
looked like yours.

Is the disk write-inhibited?

Hmm.

I added comments at the end of the lines and now it works:

Hmmm. No manpage for cn/dl/kl? Major / minor device numbers?
[reading the kernel source]
Aha. /dev/ttyl1 is what I am looking for. But the interrupt vector seams
to be wrong.
But still trouble with the dhv. Maybe wrong interrupt vector too? Maybe
I compile a kernel with support for a DZQ11...

No. It seams that
I made the mistake to reboot using reboot(8) insted of
power cycling the machine when fsck modified the file system. Didn't
notice that / was mounted r/w.

OK--that at least fixed the "three handlers" (or whatever) error message.
I haven't looked in detail at the parsing code for autoconfig so I don't
know why this is happening. I may poke at it tonight if I have the energy,
though of course Steve has the knowledge to do it more easily. :-)

It's possible that your DHV board is simply strapped for something other
than 310.
Normaly I use the console for booting only and then I
telnet to the
machine.
Likewise.
But I wane connect some terminals to the PDP-11 at the
VCFe, so
the visitors can log in play around.
Not a bad plan.
[fsck trouble]
I typically use "reboot -n" in such circumstances.
