Intel Desktop Board DP965LT Technical Product Specification
1.5 Intel
®
The Intel P965 Express chipset consists of the following devices:
• Intel 82P965 Memory Controller Hub (MCH) with Direct Media Interface (DMI)
interconnect
• Intel 82801HB I/O Controller Hub (ICH8) with DMI interconnect
The MCH component provides interfaces to the CPU, memory, PCI Express, and the
DMI interconnect. The ICH8 is a centralized controller for the board's I/O paths.

USB

The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCI-
and EHCI-compatible drivers.
The ICH8 provides the USB controller for all ports. The port arrangement is as
follows:
• Six ports are implemented with stacked back panel connectors
• Four ports are routed to two separate front panel USB headers
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.

Serial ATA Interfaces

The board provides six Serial ATA (SATA) connectors, which support one device per
connector.
1.5.2.1 Serial ATA Support
The ICH8's Serial ATA controller offers six independent Serial ATA ports with a
theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed
on each port for a maximum of six Serial ATA devices. A point-to-point interface is
used for host to device connections, unlike Parallel ATA IDE which supports a
master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the
operating system. The Serial ATA controller can operate in both legacy and native
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14
