/etc/dtab ... Yes, that does fix the problem!
That's the name - thought devtab wasn't right.
Glad it works now
Robin
Thanks very, very much ...

If it is what I think it is then you will need to add the device to
/etc/devtab (I think that's the file). 2.11 doesn't just
detect what's
there. The kernel build puts the drivers in place but it's
devtab that
switches them on.

Hi Guys,
I've got a 11/73 with 2.11BSD. The hardware configuration
is pretty
typical - RQDX3, DEQNA, TK50, and one DZQ11.
Everything
runs fine, but
now I need to install a second DZQ. The first DZQ
has csr
160100 and
vector 300, so according to my calculations the
second should be at
160110 and vector 310. I set the switches, install the
card, and then
edit my system configuration to change NDZ to be
2, rebuild
the kernel,
reboot, and, .... Disappointment!
When it gets up to init, it says:
init: configure system
dz 0 csr 160100 vector 300 attached
ra 0 .... 172150 .... 154
tms 0 .... 174500 ... 260
... etc ...
nothing about the second DZQ. Everything else still works,
including
the original DZQ11, and it boots up just fine
except that there's no
sign of the second DZQ11.
I figured I made a mistake building the kernel, so I
double check my
kernel configuration and yes, the file dz.h
contains
"#define NDZ 2".
Just to be safe I delete all the objects from my
machine's
configuration directory and rebuild the entire kernel from sources
(takes a couple of hours on a 11/73!). Still no joy - init
only finds
one DZ... And I'm sure I'm booting the
new kernel because of the
timestamp it prints out when you boot it.
At this point I figured it's a hardware problem. Just to
be sure, I
pulled out both DZQs and swapped the switch
settings on the
two cards.
This makes the original DZQ card now the
"second" one at
160110/310 and
the new card the "first" DZQ at
160100/300. Put it all back
together
and boot it up again - same results! Init finds
the first
DZ but not
the second! Moreover, all the serial ports on the
back that are now
connected to dz0 (which is the card that used to be the second dz)
still work! Of course, the ports on dz 1 (which is the card
that used
to work) are now dead. It seems like the two
DZQ11 cards must be OK.
Oh, and BTW, I even used the 11/73's console ODT to verify
that all
addresses from 17760100 to 17760117 respond.
The only explanation I'm left with is a configuration problem. Is
there something I don't know about rebuilding the 2.11bsd
kernel? Is
160110/310 the wrong location for the second
DZQ11?
Thanks much, any suggestions are appreciated.
