Check to make sure that Stealth 3D 2000 Pro is properly seated in its PCI slot and that the monitor cable is firmly and correctly connected to the Stealth 3D 2000 Pro. For more information, please see the Stealth 3D 2000 Pro Installation Instructions.

Check to make sure that all software is correctly loaded and that the software configuration settings correspond to your operating system and applications. For more information, please see Installing Software for Stealth 3D 2000 Pro.

Booting problems

• No Video
• System hangs
• System beeps

Solutions

• Make sure the card is seated properly in its expansion slot and the monitor cable is securely fastened to the card.
• Check to see if your monitor is getting power. You should double check the electrical cable and the power switch.
• Make sure your monitor cable has the proper pin-out configuration. It should be able to work with a standard IBM VGA DB-15 analog graphics adapter.
• Check if there is another display adapter in your system, or if your system has built-in video on the motherboard. You should remove or disable it. Your dealer or system user guide may be able to assist you.
• Check other cards in your system that might be using the same addressing space, for example, network or modem cards.
• Disable any VIDEO ROM BIOS shadowing at location C000-C7FF in your PC's CMOS setup. You may find the option located in the 'Advanced CMOS Setup'.
• Try to install the card to a different PCI slot.
• Try the card in another machine. If the card works properly in another computer, there is a conflict between the system configuration and the card. If you have tried all above suggestions, please contact the Technical Support for additional help.

Note: The Stealth 3D 2000 PRO card uses the following address areas.

I/O Address	3B0-3DF
Memory Address	A000-AFFF, B800-BFFF
Video BIOS	C000-C7FF

Video Problems

• Video Flicker
• Scrambled Video
• Screen Display is Small
• Monitor is not Listed

Solutions

• Video Flicker

Increase the vertical frequency for the resolution that you are using. Do not specify a frequency that exceeds your monitor´s frequency range.

• Scrambled Video

It is most likely that the selected frequency is not supported by your monitor. Select an alternative frequency that is supported by your monitor. For information on what resolutions and frequencies your monitor can handle, refer to the monitor´s user manual or contact your monitor manufacturer.

• Screen Display is Small

Use a lower vertical refresh rate. The selected vertical refresh rate may be too high for the monitor to support it. A reduced screen size may be the result

Note: For information on what vertical frequencies your monitor can handle, refer to the monitor´s user manual or contact your monitor manufacturer.

• Monitor is not Listed

To set up the video card for your monitor you will need the vertical and horizontal frequencies along with the polarity settings for each resolution. Using the InControl Tools mode utility for Windows you can configure your monitor by selecting the User Defined Monitor option.

Note: For information on what vertical frequencies your monitor can handle, refer to the monitor´s user manual or contact your monitor manufacturer.

Difficulty Starting Windows and Other Applications

Solutions

• Check your CONFIG.SYS file for a memory manager like QEMM386, EMM386, or 386MAX. A memory manager may be mapping devices in the video area, particularly in the "A000” or "B000” page. All Diamond cards use the memory area "A000-C7FF” exclusively.
• The following examples will help you to reserve the required memory area for your Stealth 3D 2000 PRO card. Optimize your memory use again after having modified your CONFIG.SYS file.

For using QEMM386 edit the following line in your CONFIG.SYS file DEVICE=C:\QEMM\QEMM386.SYS

add X=A000-C7FF, and for Stealth Option ST:F ST:M also add XST=C000

Example: DEVICE=C:\QEMM\QEMM386.SYS X=A000-C7FF XST=C000

In the SYSTEM.INI file, find the section that starts [386ENH]. Remove the line

DEVICE=MONOUMB2 ("Rem” the line with a semicolon at the beginning).

For using 386MAX edit the following line in your CONFIG.SYS file DEVICE=C:\ 386MAX\386MAX.SYS

add EXCLUDE=A000-C7FF

Example: DEVICE=C:\ 386MAX\386MAX.SYS EXCLUDE=A000-C7FF

In the 386MAX directory edit the file 386MAX.PRO, Place a semicolon (;) in front of the VGASWAP command.

Also check for further commands that may map memory areas conflicting with the video memory area A000-C7FF.

If this does not work, re-install 386MAX and select "NO” for the installation options ROM SEARCH, MDA AREA, and VGASWAP.

For using EMM386 edit the following line in your CONFIG.SYS file DEVICE=C:\DOS\EMM386.EXE

add X=A000-C7FF

You may need to remove HIGHSCAN

Example: DEVICE=C:\DOS\EMM386.EXE X=A000-C7FF

In the SYSTEM.INI file, find the section that starts [386ENH]. Edit the file and add the following statement: EMMExclude=A000-C7FF

If you have previously used MEMMAKER (DOS 6.x), run MEMMAKER again.

• Try to disable the following settings, because of possible conflicts with the driver installation: Wallpaper, 32-bit disk access, or 32-bit file and access Network drivers Screen Saver.

• Disable any programs that are loading automatically when starting Windows, for example, from the STARTUP group, RUN or LOAD lines from the WIN.INI file. Remove all programs from the STARTUP group and place semicolons (;) before the 'LOAD' and 'Run' lines in the WIN.INI file.
  
  
  
  
  
  
  
  
  
  
  

General Protection Fault (GPF) in Windows

Solutions

Follow the steps below to determine the cause of the problem.

• Change your display driver to 'Microsoft Standard VGA' - not 'VGA Version 3.0'
• If the problem still exists, an application may have been corrupted or has a conflict with Windows. Re-install the application and/or contact your application vendor for additional help.
• If the problem no longer exists, reset the display to the Stealth driver. Then edit your CONFIG.SYS file and "rem” all lines except of

DEVICE=C:\DOS\HIGHMEM.SYS

FILES=XX

BUFFERS=XX

for example: rem DEVICE=C:\DOS\ANSI.SYS

Then edit your AUTOEXEC.BAT file and "rem” all lines except of the PATH= statement.

Start your system again.

• If the GPF does not show, check your CONFIG.SYS file for a proper memory exclusion. Then add the”rem”-lines back one at a time to identify the source of the problem.
• If the GPF still shows contact the Technical Support for additional help.
