I have been in touch with Foxconn several times today, this bug also affects:
P5E WS and P5E WS PRO
MSI P965 series
It is the BIOS that is defective, not the chipset.
American Megatrends (AMI) shipped the defective BIOS, if yours is an Award BIOS, this is not an issue.
I've been told to expect the Foxconn fix within a matter of days, users of ASUS or MSI motherboards are encoraged to contact them for the fix and reference that Foxconn has confirmed that the AMI BIOS is defective.
