I would look at the BIOS first. Unless something is really haywire,
the IRQs are probably okay.

Windows will want to use IRQ4 for COM1 and IRQ3 for COM2 by default.
According to Windows, I only have a COM1 configured on my box but I
never use it.

Look in Device Manager, Ports, Communications Port (COM1), Properties
the Resources tab. If it is NOT IRQ4, we should figure out how it got
changed.
