•
Intel recommends that you install the Matrox* video card in slot 3, and you
connect the bottom DVI port to the monitor's VGA connection with a DVI-to-VGA
adapter.
2.3.3
Rear Panel Connectors
•
Connect a USB or PS/2 keyboard and/or mouse to the rear panel connectors.
•
If using the video graphics card, connect the monitor to the PCIe x1 graphics card.
2.3.4
SPI Boot Devices
The BIOS is located on the SPI flash bootable devices. The CRB supports two SPI flash
devices (SPI0 & SPI1) with the Descriptor, Soft-strap and ME residing on SPI0, and
the BIOS residing on SPI1. The in-circuit Dediprog tool provides a way to program the
flash memories. See
on page 38.
Normal Operation Mode (Default)
•
When power is applied to the CRB, the switches used (U2J2 and U2J3) will
automatically connect the PCH SPI signals to the SPI flash device.
•
For the switch to function correctly in Normal Operation Mode, jumper J3J3 and
J3J4, and the SPI program header (J2J2) for Dediprog SF100 must be empty.
