The motherboard provides one PCI Express x16 slot, one PCI Express x1 slot,
and two 32-bit PCI bus slots.

PCI Express Slots

The PCI Express slot, as a high-bandwidth, low pin count, serial, interconnect
technology.
PCI Express architecture provides a high performance I/O infrastructure for
Desktop Platforms with transfer rates starting at 2.5 Giga transfers per second over
a PCI Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general
purpose I/O. Also, desktop platforms with PCI Express Architecture will be designed
to deliver highest performance in video, graphics, multimedia and other sophisticated
applications. Moreover, PCI Express architecture provides a high performance graphics
infrastructure for Desktop Platforms doubling the capability of existing AGP8x de-
signs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers.
