Theory of Operation—Mobile Intel ® 915GME Express Chipset
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 36 ).
• 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 SVideo connector (not functional)
3.4.3.1 PCI 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.
3.4.3.2 SATA 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.
3.4.3.3 IDE Support
The evaluation board has a 40-pin connector for the ICH6-M’s integrated IDE controller.
This connector supports up to two Ultra ATA/100 hard drives; one master and one
slave.
3.4.3.4 USB Ports
The evaluation board provides eight USB (2.0) ports on the rear panel and two
additional ports through the front panel header. (J8G1).
There are four UHCI Host Controllers and two EHCI Host Controllers. Each UHCI Host
Controller includes a root hub with two separate USB ports each, for a total of eight
legacy USB ports.
Each EHCI Host Controllers includes a root hub that supports up to four 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).
3.4.3.5 VGA Connector
A standard 15 pin D-Sub connector on the rear panel provides access to the analog
output of the Intel GMA 900. The integrated graphics supports a maximum resolution
of 2048 x 1536 @ 85Hz. This can be connected to any capable analog CRT or flat panel
display with analog input.
When used in conjunction with any of the other display options, the displays can
operate Dual Independent mode. This allows the unique content to appear on each
display at unique refresh rates and timings.
