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.

'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.
