Here's a weird one (kinda OT)

The TPO's were 3COM 509's (bad children) I had many issues with those
adapters, I especially had issues with them playing well with others.
On a few installs of Novell and Win NT servers, when 2 or more of these
were in the servers I found that they had to be installed one at a time
and configured one at a time then they could all be installed and
tested... However have a 509b-TPO and another nic like SMC or Intel
and talk about seeing a piece of h/w throw a tantrum.
