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.

1.2 Board Differences

This TPS describes these Intel Desktop Boards: D925XCV and D925XBC. The Desktop Boards are identical with the exception of the items listed in Table 1.
