1
Installing the G95 Display Adapter
Installation of the adapter consists of installing a 2 MB or 6 MB memory module (if not already
installed) on the G95 board and installing the board itself. You can also install two boards for dualscreen capability.
See the on-line System Reference document delivered with the system for details on opening and
closing the computer, identifying PCI expansion slots, and adding expansion boards.
WARNING Follow all warnings and cautions in servicing instructions. If you fail to follow documented,
approved procedures, personal injury or damage to equipment can result.
CAUTION Use an anti-static wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
See the following for location of basic board components.

Install the Memory Upgrade
If the G95 board does not already have the required 2 MB or 6 MB memory upgrade, perform the
following procedure. If the memory upgrade is already installed, skip this procedure and see the
“Install the Boards” section below.
To install the memory upgrade:
1. Place the G95 board component-side up on an anti-static surface.
2. Remove the memory upgrade card from its package, and orient it so that the two keyed connectors
match the corresponding connectors on the G95 board. See diagram above for details.
3. Press the memory upgrade card firmly into the connectors until seated.
4. Go to the “Install the Board(s)” section below.
Install the Board(s)
To start the installation:
1. Turn off power to the computer and to the monitor.
2. Open the computer to access the PCI expansion slots.
3. Select the PCI expansion slot(s) into which you will install the board(s), as follows:
−
For a TD-x10 or TD-x12 deskside system, install the board in PCI slot 4 for a single-screen
system; install the boards in PCI slots 3 and 4 for a dual-screen system.
−
For a TD-x10 desktop system, install the board in PCI slot 3 for a single-screen system; install
the boards in PCI slots 2 and 3 for a dual-screen system.
−
For a TD-x20 or TD-x25 deskside system, install the board in PCI slot 3 for a single-screen
system; install the boards in PCI slots 2 and 3 for a dual-screen system.
−
For a TD-x20 or TD-x25 desktop system, install the board in PCI slot 5 for a single-screen
system; install the boards in PCI slots 4 and 5 for a dual-screen system.
−
For a TD-225 system, install the board in PCI slot 3 for a single-screen system; install the
boards in PCI slots 2 and 3 for a dual-screen system.
4. Remove the slot covers from the selected PCI slots. Retain the screws from the slot covers; you
will use them to secure the boards to the computer’s chassis.
To disable VGA for dual-screen operation:
1. Ensure that both G95 boards are identical.
2. Select the board on which you want to disable VGA.
3. Move the DIP switch labeled “2” to the ON position to disable VGA. See the diagram above for
details.
NOTE The VGA-enabled board drives the top left monitor in a dual-screen configuration.
To install the G95 Display Adapter:
1. Align the board with the PCI expansion slot, making sure the gold-fingered connectors on the
board’s edge are aligned properly with the slot connector.
2. Push the board into the slot firmly and evenly until it is fully seated in the slot connector.
3. Inspect the connection. If it does not appear to be correct, remove and re-install the board.
4. Use the screws you removed previously to secure the board to the computer’s chassis.
To finish the installation:
1. Close the computer.
2. Make sure that the InterPro-27 monitor is turned off.
3. Connect the supplied video cable (MCBL186A8) to the blue video output port on the G95 display
adapter.
4. Connect the other end of the video cable to the video input port on the InterPro-27 monitor.
Installing the G95IP27 Video Display Driver
The G95 adapter uses the G95IP27 video display driver. If you do not have a diskette containing the
display driver or if the diskette is damaged, you can obtain a copy of the driver from Intergraph Online
at http://www.intergraph.com/drive_update.stm or the Intergraph Bulletin Board Service (IBBS) at
205-730-8786 or 205-730-6504. You can also create a backup diskette containing the driver using the
systems’ InterSite Version Manager utility.
See the README.TXT file that accompanies the driver for additional information.
