Hmmm.... Not sure that I qualify as a guru.  Can you provide more details as
to in what way Ethernet 'bombed'?  We used to have mucho ethernet problems
until IBM figured out what was happening and sent a replacement ethernet
driver.  The new driver is one of the patches in the archive at
bikini.cis.ufl.edu.

The Dec. '88 Release of AOS 4.3 supports 2 CPUs in and RT 6152.  I do not
know if IBM every released any instructions although I vaguely remember
seeing them drift by some where.  If memory serves, one also needs a
modified version of the 6152 configuration diskette (the one with the
diagnostics) so the bus addresses of the second CPU card can be set.  One
CPU could be used to run the X server leaving the other for more useful
computations.

Hope this helps.
