   Do you have a 100Mbit switch? You can't do both modes without a switch.
If you have the machine connected by a cross-over cable, be warned that the
Pro/100B's auto speed detection doesn't deal with this correctly when the
cards on both ends are Pro/100B's. It does seem to work when one card is
a DEC chip based card, however.
