This looks like the same problems we've encountered here dozens of times.
Perhaps this shoudl be a monthly posting :-).  Anyway, it looks like you
forgot to use the devices command to set the memory addresses correctly.
The parameters you want to change are rsa (98000), rea (99fff), brsa (9a000),
and brea (9ffff).  The parens are my values.  The default values are just
plain wrong (typical IBM).  You also need to set the interrupt level to 3
and the frequency to every 18.3ms.  You also need to set the jumpers on the
board properly.  For the above values the settings are as follows...

The interrupt level is right above the edge connector.  Set it to three.

The memory address jumpers are w10 to w13.  Set them to horizontal,  
horizontal, vertical, vertical.  Sort of _ _ H H

The interrupt frequency is w14 and should be set at position 2.

I'm sorry I can't be more exact, but the positions are hard to explain.
If you have the red "User Setup Guide and Options Installation book it's
in there under network adapters.  Good luck.

Check /etc/rc.tcpip  You need the host command in there and the name used
must match the /etc/net name and the name in the hosttable.  Also, fixing
the jumpers as above might help.

>Anyone else regret going with AIX??

I had no choice (it was free, so we took it) but I think I'd prefer a
"real" Unix.
