I, too, have a problem with the 4-port buffered async board.  I set the
interrupt to 10, as 9 and 11 were in use (yes, I know that they are
supposed to be shareable).  The kernel then complained that there
couldn't be devices using interrupts 10 and 0 (yes, zero).  So, I've
yanked the board back out and won't do anything with it until I have
nothing better to do.  I can't find any reference to interrupt 0, but
then IBM chose not to ship me full documentation, either.

My system is a 6150-135, 16 MB, 3 310 EESDI drives, APA16 monitor, 2
Ethernet interfaces, and it runs the December '88 AOS release.

Previously, I ran into another problem configuring the kernel.  Apparnetly,
the SGP option must be included if you have 16 MB, but isn't necessary for
an 8 MB machine.  Their kernel configuration sources are pretty ugly, BTW.
This problem looks like a hardware conflict with other RT models that
weren't ifdef'ed properly.  The SGP option just happened to prevent the
nastiness.  Supposedly, the SGP option is necessary only if you have older
RT models on the network (I don't).

Nonetheless, the IP routing works, and the latest Berkeley networking and
mail code ported quite easily.  It still needs a lot of the BSD fixes from 
the past year and half, though.

Always grateful to have someone else fix my problems.  8-)

Regards,
Chuck
