Graphics Subsystem
The graphics subsystem is part of the Intel Core
TM
i7 processor and the PCH QM77. While the graphics
controller is located within the Core
TM
i7 processor, the different interfaces like DisplayPort, SDVO and
VGA are moved to the PCH. The SC1-ALLEGRO offers two Mini DisplayPort (mDP) interfaces in the
front panel.
Adapters to convert Mini DisplayPort to any other popular interface standard are available.
A 3
rd
DisplayPort or an SDVO port is fed in a multiplexed manner to the on-board connector J-SDVO.
EKF expansion boards like PCS-BALLET feature the possibility to gain access to the 3
rd
DisplayPort
interface. Additionally EKF offers a bundle of expansion boards that contain a display transmitter to
provide a DVI channel via a pure digital DVI-D connector.
As an option, the SC1-ALLEGRO can be equipped with an ordinary HD D-Sub 15-lead connector (VGA
style). This connector is suitable for analog signals only. Nevertheless also flat-panel displays can be
attached to the D-Sub connector but with minor reduced image quality.
Independent from the video connector actually in use, Mini DisplayPort, DVI or VGA, the VESA DDC
standard is supported. This allows to read out important parameters, e.g. the maximum allowable
resolution, from the attached monitor. DDC Power, +3.3V or +5V on DisplayPort or VGA connector
respectively, is delivered via a resettable fuse to protect the board from an external short-circuit
condition (0.5A).
Graphics drivers for the Core
TM
i7 can be downloaded from the Intel web site.
LAN Subsystem
The Ethernet LAN subsystem is composed of four Gigabit Ethernet ports: One Intel 82579LM Physical
Layer Transceiver (PHY) using the PCH QM77 internal MAC and three Intel 82574IT Gigabit Ethernet
Controllers. These devices provide also legacy 10Base-T and 100Base-TX connectivity. Two of the
Ethernet ports are fed to two RJ45 jacks located in the front panel, the others are attached to the
CompactPCI ®
Serial interface on P6. Each port includes the following features:
<
One PCI Express lane per Ethernet port (250MB/s)
< 1000Base-Tx (Gigabit Ethernet), 100Base-TX (Fast Ethernet) and 10Base-T (Classic Ethernet)
capability.
< Half- or full-duplex operation.
<
IEEE 802.3u, 802.3ab Auto-Negotiation for the fastest available connection.
< Jumperless configuration (complete software-configurable).
Two bicoloured LEDs integrated into the dedicated RJ-45 connector in the front panel are used to
signal the LAN link, the LAN connection speed and activity status. A further bicoloured LED in front
panel labelled EB displays the state of the backplane network ports.
Each device is connected by a single PCI Express lane to the PCH. Their MAC addresses (unique
hardware number) are stored in dedicated FLASH/EEPROM components. The Intel Ethernet software
and drivers for the 82579 and 82574 is available from Intel's World Wide Web site for download.
When managing the board by Intel Active Management Technology (iAMT), the dedicated network
port to do so is accessible by the RJ45 connector GbE1 (the upper port within the front panel).
