1.1 PCI Bus Terminology Change

Previous generations of Intel

Desktop Boards used an add-in card connector referred to as PCI.

This generation of Intel Desktop Boards adds a new technology for add-in cards: PCI Express*.
The 32-bit parallel bus previously referred to as PCI is now called PCI Conventional.
