Hi, sorry for the delay in replying, took me ages to sort this out and
while trying something I forgot to put double-quote at the end of an
ifconfig line in /etc/rc.conf, preventing me from getting into
multi-user mode and neither of my usual editors would work in single
user mode. It took me a while to figure out how to fix it.

I couldn't figure out a way of forcing full-duplex mode.

To my knowledge Windows 98 doesn't keep a host table of it's own, not
one that can be hand-editted, anyway. Mason's host table is the
/etc/hosts file (which has entries for rook), no named or other DNS
servers are running.
/etc/hosts:
127.0.0.1 localhost.home.lan localhost
192.168.x.x mason.home.lan mason
192.168.x.x mason.home.lan.
192.168.x.x rook.home.lan rook
192.168.x.x rook.home.lan.

According to the 3com Diags, the NIC is in full-duplex mode.
