Intel® 945GME Express Chipset—Theory of Operation

In addition to the internal I/O connections listed above, the evaluation board also contains the following I/O on the rear panel (as illustrated in Figure 3 on page 38).

•Five USB ports on back panel.

•VGA connector

•PS/2-style keyboard and mouse ports

•LAN connector

•One 9-pin serial connector

•One IrDA port

•One TV D-connector

3.4.3.1PCI Express* Support

The evaluation board provides access to one x16 PCI Express* connector. Any industry standard x16 PCI Express* video adapter may be used with this interface. The evaluation board also provides access to two x1 PCI Express* connectors. Any industry standard x1 PCI Express* adapter may be used with these interfaces.

3.4.3.2SATA Support

The evaluation board provides support for up to two SATA disk drives. The SATA controllers are software compatible with IDE interfaces, while providing lower pin counts and higher performance.

These are two SATA connectors on the evaluation board. The SATA Cable connect provides both signalling and power white the SATA Direct connect only provides signals (the user typically uses an ATX power supply for the drive power).

3.4.3.3IDE Support

The evaluation board has a 40-pin connector for the ICH7-M’s integrated IDE controller. This connector supports up to two Ultra ATA/100 hard drives; one master and one slave.

Note: Desktop hard drives must be powered by an external ATX power supply.

3.4.3.4USB Ports

The evaluation board provides five USB (2.0) ports on the rear panel and three additional ports through headers (J6H2 and J7E2).

There are four UHCI Host Controllers and an EHCI Host Controller. Each UHCI Host Controller includes a root hub with two separate USB ports each, for a total of eight legacy USB ports.

The EHCI Host Controller includes a root hub that supports up to eight USB 2.0 ports. The connection to either the UHCI or EHCI controllers is dynamic and dependant on the particular USB device. As such, all ports support High Speed, Full Speed, and Low Speed (HS/FS/LS).

3.4.3.5VGA Connector

A standard 15 pin D-Sub connector on the rear panel provides access to the analog output of the Intel® 945GME Express Chipset. The integrated graphics supports a maximum resolution of 2048 x 1536 @ 75Hz. This can be connected to any capable analog CRT or flat panel display with analog input.
