Q & A
Q1: There is an irregular beep sound when booting up the system after installation and nothing on
the monitor screen.
A1: Make sure that your system has been connected to the monitor with cable correctly. Also check the
power cable is well connected to the monitor. If the problem still exists, remove the VGA card from the AGP
slot, make clear the golden-plated pins of the VGA card with eraser, insert it again into the AGP slot and
reboot your system.
Q2: Window95/98 informs that the display setting is still incorrect after installation and restarting.
A2: Drivers for the new display adopter and the existing drivers may conflict with each other or
Windows95/98 does not recognizes the display adopter correctly. Follow the procedures below.
Reboot your system to Safe mode, select ‘Start’%’Settings’%’Control panel’%’System’%’Device Manager’
and delete all controllers that have been set in “Display adopter”.
Delete a proper INF file regarding the display adopter (normally located in C:\Windows\INF\Other) and the
same INF file in the INF folder. Set to “Standard PCI graphics adopter” and reinstall the display drivers.
Q3: The monitor is not capable of high resolution and refresh rate.
A3: The monitor driver has not been set correctly.
Reinstall the monitor driver provided by its manufacturer or set to “Plug and Play monitor”.
If your monitor does not support DDC, set to “Super VGA 1600X1200” for your convenience.
Q4: Dual monitor is not configured in Windows 98.
A4: In order to use dual monitor in Windows 98, two display adopters need to support Primary and
Secondary display each. If you set the SIGMA display adopter (AGP) to the Primary, the other PCI display
adopter should be set to the Secondary.
When restarting Windows 98, it says the secondary display controller has been detected on your second
monitor. At this time, if you install PCI display driver in the display properties of the primary monitor, you
can use the display controller with two monitors.
Q5: Display drivers are not installed in Window NT4.0.
A5: Basically the SIGMA display adopter supports AGP2X or higher.
As Windows NT does not support AGP2X, you need to install Windows NT 4.0 Service pack3 or higher.
You can download Windows NT 4.0 Service Pack3 at www.microsoft.com.
Q5: When running 3D games, the system is halted.
A5: There is a problem in DirectX driver setting.
Reinstall updated display drivers and DirectX drivers. Select C:\Program files\DirectX\Setup and run
“Dxdiag.exe”. Select “Display” tab and check whether Direct3D works correctly by pressing “Test” tab in the
Direct3D”.
Q6: When running the SIGMA VCD player, Windows 95/98 says that the SIGMA graphics card is not
detected and it refuses to run the SIGMA VCD player.
Q6: This comes from not detecting the SIGMA display adopter.
You should use BIOS provided by SIGMACOM to run the SIGMA VCD player. (Error message appears if
you use another BIOS or you update it from Internet or BBS)
Update BIOS from SIGMA Home page at www.sigmacom.co.kr.
Q7: Nothing on the screen when running the SIGMA VCD player.
A7: Generally VCD 2.0 title has been designed for playing movies by Interactive navigation. In case of
playing a simple DAT file without Interactive, there is no problem to run the motion file. However when
loading and playing a VCD title that does not have interactive function, it refuses to play because the
SIGMA VCD player is designed for interactive navigation.
Q8: When running the SIGMA VCD player, the system is halted or gives an error message that it is
quitted by mis-calculation.
A8: It may come from S/W MPEG driver.
If there is another S/W MPEG driver in your system (ex: Compcore, Mediametics,Xing …) before installing
the SIGMA VCD player, it may cause the conflict. Reinstall the SIGMA VCD player.
If the problem still exists, open “System.ini file” and delete another MPEG drivers that registered at MCI
part. After that, reinstall the SIGMA multimedia programs.
Q9: When running the SIGMA VCD player, the motion picture is step-played or stopped.
A9: It may be played slowly if your CD-ROM Drive is connected to the IDE connector as Slave.
Change its connection to the Master.
