[comp.unix.wizards] 2 ethernet interfaces on M-Vax II, one delqa, one deqna

beth@batcomputer.tn.cornell.edu (Beth Elias) (01/10/89)

Does anyone know of any software or hardware weirdness
that would keep our MtXinu kernel on a Micro-Vax II
from recognizing our new delqa board? 

We already have a deqna that configures just dandy,
but the delqa is never seen. We have already done the
obvious, switched addresses, plugged both into the
correct network, had the board swapped for another.

The result is that the hardware checks out fine and
we are left with the thought that the delqa does not
do it's deqna emulation good enough for the deqna
driver to recognize it. 

We need both boards 'cuz we gotta be a gateway...

Any ideas or thought would be appreciated.

Thanks.

It turns out that the DELQA takes longer to self-test than the DEQNA.
The probe routine hangs out for a while, but not quite long enough.
Eventually, it decides that the board is either not there or dead,
and it doesn't configure.  Some time later the device comes ready, but
by that time the kernel has already given up.  I'm told that you run
into similar problems when you try to use a DELUA with the DEUNA driver.

I had this exact same problem when I tried to use a DELQA in my MicroVAX
Internet gateway.  I have fixed the qe driver so that it can talk to the
DELQA, and can send diffs to people who need them.
