Well, if I boot both machines to Win9x, I can setup Intel card to 10Mbps/full-duplex and I can setup my 3com card to 10Mbps/full-duplex too. Its full name is 3Com EtherLink III LAN PC Card (3C589D). I get over 500KBps transfer easily. I guess it's impossible with duplex mismatch. If I boot both machines to FreeBSD, I can setup fxp0 to 10Mbps/full-duplex but cannot setup ep0 to full-duplex. Here I cannot get over 30Kbps. If I change fxp0 to half-duplex, I get full speed. So I conclude 3C589D does support full duplex at the hardware level.
