While the possibility of purchasing a new Linux distribution on CDROM
is under consideration in order to try and get something to run on this
system, we've also been trying to figure out why no tulip drivers will
work with the current kernel.
We've pretty much eliminated network config errors, so it would seem
that the problem is that something isn't getting the tx working. Ifconfig
shows plenty of packets being read, but the number of transmits is only
one or two after trying to ping outside the box.
I've tried reading the code, and that would take a lot longer than
ordering and installing a new kernel :^)
