Dear Peter,

I had the same problem. COM1 is not connected on the mainboard only the COM2
so you have to use the 2F8 and IRQ3 in BIOS settings.

The you have to see:

sio0: <16550A-compatible COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on
acpi0
sio0: type 16550A 

If you "...not in bitmap of probed irqs..." it will NOT work.

Best regards,
Andre van Amerongen
