IRQ 3 is normally reserved for sio1.  You can't have two sio ports on
the same IRQ.  This is a hardware limitation.

Yes.  FreeBSD enables interrupts on all boards, and they're
conflicting, so you don't get an interrupt.  Change the IRQ of one of
the interfaces.

Considering it's not supported, you shouldn't be very surprised by
this result.  ISTR that somebody's working on it, though...  Here we
go (from the 3.0-BETA /sys/i386/conf/LINT file):

# The `xl' driver provides support for the 3Com 3c900, 3c905 and
# 3c905B (Fast) Etherlink XL cards and integrated controllers. This
# includes the integrated 3c905B-TX chips in certain Dell Optiplex and
# Dell Precision desktop machines and the integrated 3c905-TX chips
# in Dell Latitude laptop docking stations.

3.0 is due for release at the end of next week.

Dialling Microsoft?  Sorry, I don't know.  What do your log files say?

BTW, it's not a good idea to come up with multiple unrelated problems
in one message.  You're liable to scare people away.  Feel free to
send out three separate messages.
