Intel Desktop Board D945PLNM Technical Product Specification 1.5 Intel® 945PL Chipset The Intel 945PL chipset consists of the following devices: • Intel 82945PL Memory Controller Hub (MCH) with Direct Media Interface (DMI) interconnect • Intel 82801G I/O Controller Hub (ICH7) with DMI interconnect The MCH component provides interfaces to the CPU, memory, PCI Express, and the DMI interconnect. The ICH7 is a centralized controller for the board's I/O paths. For information about The Intel 945PL chipset Resources used by the chipset Refer to http://developer.intel.com/ Chapter 2 1.5.1 USB The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH7 provides the USB controller for all ports. The port arrangement is as follows: • Four ports are implemented with dual stacked back panel connectors adjacent to the audio connectors. These connectors are yellow, indicating that they support USB anti-theft circuitry. • Four ports are routed to two separate front panel USB connectors. These connectors do not support USB anti-theft circuitry. NOTE USB anti-theft circuitry requires the use of Intel® Platform Administration Technology software. Contact your Intel representative for more information. NOTE Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices.

USB
The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and
EHCI-compatible drivers.
The ICH7 provides the USB controller for all ports.
The port arrangement is as follows:
•
Four ports are implemented with dual stacked back panel connectors adjacent to the audio
connectors.
These connectors are yellow, indicating that they support USB anti-theft circuitry.
•
Four ports are routed to two separate front panel USB connectors.
These connectors do not
support USB anti-theft circuitry.

NOTE
USB anti-theft circuitry requires the use of Intel
®
Platform Administration Technology software.
Contact your Intel representative for more information.

NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet FCC
Class B requirements, even if no device is attached to the cable.
Use shielded cable that meets the
requirements for full-speed devices.
