Intel 317443-001US Clock Generation, POST Code Debugger, Keyboard/Mouse, Primary System Clocks

Theory of Operation—Intel®945GME Express Chipset

When used in conjunction with the other display options, the displays can operate in Dual Independent mode. This allows unique content to appear on each display at unique refresh rates and timings.

3.4.3.6Keyboard/Mouse

The keyboard and mouse connectors are PS/2 style, six-pin stacked miniature D-Sub connectors. The top connector is for the mouse and the bottom connector is for the keyboard.

3.4.3.732 bit/33 MHz PCI Connectors

Two industry standard 32 bit/33 MHz PCI connectors are provided on the evaluation board. These slots support 5 V devices.

3.4.3.8Ethernet Gigabit LAN Interface connector

The evaluation board provides one industry standard Gigabit RJ45 LAN Interface Connector (Integrated with the dual USB connector).

3.4.3.9LVDS Flat Panel Display Interface

The evaluation board provides one forty-four pin LVDS video interface connector. The provided LVDS connects to most 18 bits per pixel (bpp) flat panel display assemblies. 24 bpp LVDS is not supported.

3.4.4POST Code Debugger

A port 80-83 display at CR6A1, CR6A2, CR6A3, and CR6A4 show the POST codes and can be used for debug information during POST. The evaluation board uses an AMI* BIOS.

3.5Clock Generation

The Intel® 945GME Express Chipset board uses a CK-410M and CK-SSCD compatible solution. The FSB frequency is determined from decoding the processor BSEL[2:0] pin settings.

The clock generator provides Processor, GMCH, ICH7-M, PCI, PCI Express*, SATA, and USB reference clocks. Clocking for DDR2 is provided by the GMCH.
