Table 7. Hardware Straps For Processor Pci Express* Interface Usage - Intel ® Core i7 User Manual

 2 x 8 PCI Express IO (or PEG)
The 2 x 8 slots are supported through the Nowata Add-In Card. Embedded Display Port (eDP)
is supported through the Eaglemont 2 add-in card.
The usage model of the processor‟s PCI Express interface needs to be configured through the
following hardware straps:

Table 7. Hardware Straps for processor PCI Express* Interface Usage

3.7.1.8
Embedded Display Port (eDP) is a feature on Intel
Note: When eDP is enabled, we can only have 1x8 PEG card. eDP lanes are multiplexed over PEG
12:15 lanes from the processor.
1. Insert the PCI graphics add-in-card in the PEG slot (J5C1), not the DDI slot.
2. To enable eDP, you need to "short" the Jumper pins of J1D1 (1-2) on motherboard.
3. Connect the side-band signals on J6D1 on motherboard, via a cable to J3C1 on the PCI
graphics.
4. For the Sideband signals, we have 2 options
5. Connect J6D1 (on motherboard) to J3C1 (on PCI graphics) through a 10-pin cable.
6. Use the BLI connector from LVDS Connector provided to connect it directly at the eDP
Panel.
3.7.1.9
The Development kit Supports x4 DMI bi-directional lanes between the Processor and Chipset.
The transmissions happen over DMI protocol. Max speed supported is 2.5GT/s. This protocol is
different from the ones on earlier platforms, and has some instructions added.
3.7.1.10
The development kit supports Intel
processor and display interfaces are supported through the chipset. The Intel
dedicated link to transmit the display related pixel information over unidirectional 2x4 lane
interfaces. The synchronization signals are directed from chipset to processor.
