PCI Express Interface (J2)
The J2 connector has 100 pins and is used for PCI Express, Serial ATA (SATA), USB, ExpressCard,
AC'97/HDA (High Definition Audio), and LPC bus.
PCI Express/ExpressCards
The I/O Hub (82801FBM) provides four x1 PCI Express lanes which can be configured to support
PCI Express edge cards or two ExpressCards.  If ExpressCards are used, one dedicated USB port
and one dedicated PCI Express lane are required for each ExpressCard and SMBus is optional.
