The system board fully supports the universal host controller interface (UHCI) and uses
UHCI-compatible software drivers. See Appendix A for information about the USB
connector pin assignments.
Boot support for a USB keyboard is present so the system can be booted with a USB
keyboard instead of a standard keyboard.

Graphics Capabilities

The system supports accelerated graphics port (AGP) and PCI graphics boards.
A PCI graphics board installs in one of the computer's PCI expansion slots. An AGP
graphics board installs in the system board's AGP connector (see the following figure).
NOTE: Computer systems that have an
unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no
device or a low-speed USB device is attached to
the cable. Use a shielded cable that meets the
requirements for high-speed devices.
