You wouldn't happen to have a Dell MB ?  I had my machine running w/
an additional 2port 16550.  I had com1-4 on irq 4,3,9,5.  I put this
in the new Dell machine and never saw com2 again.  I can jumper the
physical UARTS as various COMs and switch IRQs - no joy.  Address 2f8
just won't probe !  It's an XPS Pro 200n.

BTW, fix your IRQs.  sio1 & sio3 should *not* use the same IRQ.
