Yes, that. I just helped someone with this problem a couple of days ago --
he had a crappy NE2000 clone attached to the same hub as his machine with
some nicer PCI card. He was getting huge numbers of collisions. Why?
Because the crappy NE2000 was trying to do full-duplex even though it was
connected to the hub with coaxial cable! Since it was a hubbed network, every
time the NE2K transmitted everyone else saw collisions. Yee ha!
