slot dedicated to supporting PCIe 1.1 option cards. Slots 2, 4 and 6 are x16 mechanical slots driven with x8
PCIe electrical links. Slots 3, 5, and 7 are x8 mechanical slots driven with x4 PCIe electrical links. PCI
Express 2.0 bas a base frequency per lane of 5.0GHz while PCIe 1.1 runs at half of this speed or 2.5GHz per
lane. The PCI Express auto-negotiation capability built-in to the motherboards‟ PCIe interface controllers
enable support for PCI Express option cards with x16, x8, x4 and x1 PCIe 2.0 or 1.1 electrical links. The
PCIe interfaces on the option cards must also support PCI Express auto-negotiation as per the PCI Express
Base Specification. Refer to the PCI Express
chapter of this manual for more information.
PCI Option Card Slot
A 32-bit/33MHz option card slot is available on the motherboard to enable system support for an option card
with a parallel bus interface. This card slot accepts either 5V or universal voltage PCI cards
Universal Serial Bus (USB)
The motherboard supports up to ten on-board high-speed USB 2.0 ports. Connectors for eight of the USB
interfaces (0 and 7) are rear panel I/O port, while the remaining two interfaces are available via an on-board
header.
Video Interface
The motherboard supports a standard VGA video connector located at the rear of the motherboard. The video
port is driven with a Graphics Processing Unit (GPU) with 8MB of video memory. This enables video
support for WUXGA resolutions (i.e. 1920 x 1200 pixels) at a 64k color depth.
Ethernet Interfaces
Four 10/100/1000Base-T Ethernet ports are located at the rear of the motherboard. Two Intel
®
82575
Ethernet controllers with dual-channel outputs are driven with PCI Express communication links on the
motherboard. This motherboard design feature ensures that the final system solution supports fastest Ethernet
network communications possible. The Ethernet interfaces are compliant with the IEEE 802.3 Specification.
The main components of the Ethernet interfaces are:
Intel
®
82575 for dual 10/100/1000-Mb/s media access control (MAC) with SYM, a serial ROM port
and a PCIe interface
Serial ROM for storing the Ethernet address and the interface configuration and control data
Integrated RJ-45/Magnetics module connectors on the motherboards require category 5 (CAT5)
unshielded twisted-pair (UTP) 2-pair cables for a 100-Mb/s network connection or category3
(CAT3) or higher UTP 2-pair cables for a 10-Mb/s network connection. Category 5e (CAT5e) or
higher UTP 2-pair cables are recommended for a 1000-Mb/s (Gigabit) network connection.

later in this chapter.)
Software drivers are supplied for most popular operating systems.
Serial ATA/300 Ports
The motherboard‟s six Serial ATA 300 (SATA/300) ports comply with the SATA II specification and support
six independent SATA storage devices such as hard disks and CD-RW devices. SATA produces higher
performance interfacing by providing data transfer rates up to 300MB per second on each port. The ICH10R
I/O Controller Hub features Intel
®
Matrix Storage Technology, which allows the ICH10R‟s SATA controller
to be configured as a RAID controller supporting RAID 0, 1, 5 and 10 implementations.
Audio Interface
Standard audio ports located at the rear of the motherboard support the Line In, Line Out and MIC audio
functions.
Trusted Platform Module (TPM 1.2)
The motherboard is compliant with version 1.2 of the Trusted Computing Group specification for Trusted
Platform Modules via the us of the Atmel
®
ATC97SC3203 TPM.
