I took some older Socket 7 boards with both ISA and PCI slots with 
CPUs ranging from an Intel 166 (no MMX) to a K6 PR300.  Tried about 5 
different PCI 100BaseT NICs and only a single generic NE2000 10BaseT 
ISA card.  In every case, the ISA card was faster than the PCI cards 
(talking to a 10BaseT hub) when doing an A-B comparison in the same 
box.  OSes were Win98 and Win2K.  I suppose I should throw in some 
Linux just to be fair, but I didn't do it this round.   To be fair, I 
used different cables and ports on the hub.

I think you've hit the nail on the head, Jay--at least it seems that 
way.  I've got a few more tests to do before I'm sure.  To say that 
I'm surprised is an understatement.

Cheers,
Chuck
