1. Getting Started

1.1 Safety Precautions

Warning!

Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should

14 ESM-2850 User’s Manual

User’s Manual

The GMCH contains one 16-lane (x16) PCI Express port intended for an external PCI
Express Based graphics card. The PCI Express port is fully compliant to the PCI Express
Base Specification revision 1.0a. The x16 port operates at a data rate of 2.5 GB/s while
employing 8b/10b encoding. This allows a maximum theoretical bandwidth of 40 GB/s each
direction. Intel 915GM/ PM may also be configured as PCI Express x1 port.
The GMCH is capable of driving a CRT, LCD panel, Analog TV and/or two SDVO devices
(SDVO ports are mixed with PCI Express). The display is the defining portion of a graphics
controller. The display converts a set of source images or surfaces, combines them and
sends them out at the proper timing to an output interface connected to a display device.
Along the way, the data can be converted from one format to another, stretched or shrunk,
and color corrected or gamma converted.
The GMCH supports two SDVO ports multiplexed with PCI Express Graphics interface.
The SDVO ports are capable of driving a variety of external TV-Out, TMDS, and LVDS
transmitter devices. SDVO devices are capable of driving a standard progressive scan
analog monitor with resolutions up to 2048x1536 at 75 Hz. This interface may be
configured for as PCI Express x1 port also.

2.3 Jumper and Connector List

You can configure your board to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected by a plastic cover) that
slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1,
2, and 3. In this case, you would connect either two pins.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
If you have any doubts about the best hardware configuration for your application, contact
your local distributor or sales representative before you make any changes.

The following tables list the function of each of the board's jumpers and connectors.
