Intel Desktop Board D915PGN/D915PSY Technical Product Specification 1.7 Intel® 915P Chipset The Intel 915P chipset consists of the following devices: • Intel 82915P Memory Controller Hub (MCH) with Direct Media Interface (DMI) interconnect • Intel 82801FB I/O Controller Hub (ICH6) with DMI interconnect • Firmware Hub (FWH) The MCH is a centralized controller for the system bus, the memory bus, the PCI Express bus, and the DMI interconnect. The ICH6 is a centralized controller for the board's I/O paths. The FWH provides the nonvolatile storage of the BIOS. For information about The Intel 915P chipset Resources used by the chipset Refer to http://developer.intel.com/ Chapter 2 1.7.1 USB The boards support up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH6 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 • Four ports are routed to two separate front panel USB connectors ✏ 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.
