Hi: I'm having this same problem with a new Abit AN8 MB, which has the 
pciexpress.

I've tried changing the BIOS settings like suggested, PLUS, even trying a 
PCI card, but still the same no response.

Does anyone have this MB and cured this problem? If so, please let me know 
as I really need that lost serial port for the UPS (no, USB won't drive it).

Thanks.
Best regards,
Jack
