I'd look out for serial port, Super-I/O or COM1 port (which is how PC-DOS named the device some 35 years ago) settings rather than anything to do with PNP. Typically you'd be able to choose from a few classic combined I/O space address and IRQ assignments in addition to a `Disabled' setting. There might be a genuine BIOS bug there as well of course as serial ports seem to be less used these days and the issue may have escaped validation. Maciej
