The other side, which I dont control, is supposedly set to 10 Full
Manual as well. I think I will have to get a box in the lab and test
for myself to see how it works where I can control both ends.

On another box at the lab, I did confirm that if I set the NIC to 10
full manual
# ifconfig sis2
sis2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=8<VLAN_MTU>
ether 00:00:24:c8:fa:de
inet 1.1.1.1 netmask 0xffffff00 broadcast 1.1.1.255
media: Ethernet 10baseT/UTP <full-duplex>
status: active
and the switch port is set to
interface FastEthernet0/33
duplex full
speed 10
it seems to work.... I wonder if the media converter I plug into is
really set to 10 Full....
