CHAPTER 2
Hardware Installation
IGS PCI VGA card automatically detects whether you are using a monochrome or color monitor. Therefore, the monitor must be turned
on before the computer, or an incorrect monitor type may be detected. This card supports most analog monitors on the market. If
monitor type is not detected during power-up, the card will default to support monochrome VGA.
These cards should be configured for the best resolution and refresh rate your monitor can support. Check the specifications of your
monitor for signal compatibility with this card and find an optimum setting to suit your applications.
WARNING !!
Static electricity can damage sensitive electronic components. Discharge your body's static electric
charge by touching a grounded surface. e.g., the metal area of the computer chassis before performing any hardware procedure.
The manufacturer assumes no liability for any damage, caused directly or indirectly, by improper
installation of any components by unauthorized service personnel. If you do not feel comfortable
performing the installation, consult a qualified computer technician.

Installing the Hardware
Jumper Setting
The IGS PCI VGA CARD has one jumper to determine the IRQ9 setting. The jumper is preset at the factory and in most cases you will
not need to change it. The jumper at location J6 enables or disables IRQ9. This allows support for existing video standards that
require an IRQ present for some software applications. This IRQ is not used or required for normal VGA operation. There is no
performance gained by either enabling or disabling this jumper.
1 .Power off the computer and disconnect the monitor cable.
2 .Remove the computer cover. If necessary, consult your system manual for removal instructions.
3 .Make sure the jumper setting and memory configuration are correct.
4 .Select an empty PCI expansion slot for the IGS PCI VGA CARD. With the slot cover removed, grasp the card by the top
edgeand carefully seat it firmly into the slot. Fasten the retaining bracket with a screw.

If the system successfully powers up and the normal DOS boot-up message appears on the screen, the IGS PCI VGA CARD is installed
properly. If the system does not boot, there are a few things you can check in the following "Hardware Troubleshooting" section.
WARNING !!
Damage to system components, the display adapter, and injury to yourself may result if power is on
during installation.
Hardware Troubleshooting
1.Make sure the PCI bus connector gold-fingers are clean and installing in PCI slot properly.
2.After power up the system, if the system's power supply vent does not work or does not hear any sound from the system,
there may be a short bridge on the card. Turn off the system and take out the card. Check on back of the card (solder
side). To see if there is any small piece of metal attached on the card and cause the short.
3.Check BIOS at location U2. Make sure all the pin and pin #1 location are installed properly.
4.Check display memory DRAM at locations U6 and U7 on IGS PCI VGA CARD. Make sure all the pins are installed or

CHAPTER 4
Windows Driver Setup
IGA Windows Driver Setup
The Integrated Graphics Accelerator (IGA) is a 64 bit high performance Windows Graphics User Interface Accelerator. Its powerful
hardware graphics drawing engine provides the fastest speed for running Windows applications. The integrated RAMDAC provides
16.7 million colors at up to 1280x1024 resolution and 64 thousand colors at up to 1600x1200 resolution. But, you can not take
advantage of all those features unless you install and setup IGA Windows Accelerated Drivers properly.
The IGA Accelerated Windows Driver supports virtual desktop. This new feature allows users to further explore the powerful capabilities
of the IGA graphics accelerator even on a small, low resolution monitor. The Windows Driver Setup program can also be used to
configure your virtual desktop environment.
There are two ways to use this setup program: 1. Normal Setup; 2. Configure Virtual Desktop Environment. Please refer to the
corresponding sections of the help document to setup your graphics accelerator.
When you finish setting up, click the button "OK" to Accept Selection.
IGA1682 PCI VGA
26
Normal Setup
To setup your IGA Graphics Accelerator without Virtual Desktop, you have to make sure that the check box "Virtual Desktop Enable"
is unchecked. For normal setting up, you have four parameters to select for configuring your IGA Graphics Accelerator: resolutions,
refresh rates, color depths and font sizes.
The highest resolution you can choose is 1600x1200. The highest color depth is 16.7 million (True Color). The refresh rate selections
are: interlaced and non-interlaced 60 Hz, 72 Hz, 75 Hz. For font sizes, you can choose either "small" font or "large" font. But, some
combinations are not available because they are either not feasible or due to hardware limitations, such as video memory size. The
Setup Program works hard to help you. It has already eliminated all non-feasible situations and combinations that your Graphics
Accelerator does not allow. But, there is one important factor the program can not predict -- your monitor. To help solve this problem,
a specific function button -- "Refresh Text" is designed to verify whether your monitor works under the desired combination.
Please follow the procedure to do the setup:
Step 1.Use the combo box "Resolution" to choose a reso-lution. For 14 or 15 inch monitors, recommended resolution is
800x600 or below. For 17 inch or other large monitors, you may choose
1024x768 or above.
Step 2.Use the combo box "Color Depth" to choose a color depth. For most
software and applications, 256 colors will be a good choice. If you
need to display real life video or photo, you may need 64k or even
16.7 million colors.
Step 3.Use the combo box "Font Size" to choose either small font or large font
for your system. For 640x480 resolution, you should use small font.
For 1024x768 and above, you should choose large font. For 800x600
resolution, you can choose either fonts.
IGA1682 PCI VGA
27
Step 4.Use the combo box "Refresh Rate" to choose a refresh frequency for your monitor. Normally, the higher refresh rate will
give better display result. But, the refresh rate setting can not go beyond your monitor's ability. Otherwise, the display
monitor may lose sync. The setup program provides an easy way to help users verify whether your monitor can work at
the selected resolution and refresh rate. When you click on the "Refresh Test" button, the program will set the monitor
to that resolution and refresh rate for a few seconds. If the text displayed in the middle of the screen is clear, you can
select that resolution-frequency combination.
Step 5.Click the button "OK" to Accept Selection.
IGA1682 PCI VGA
28
Cofigure Virtual Desktop Environment
The IGA Graphics Accelerator is a powerful graphics interface card. A 2 Mb board can support as high as 1600x1200 resolution in 256
colors. But, a monitor running at that high resolution may cost a lot of money. The Virtual Desktop of the IGA Graphics Accelerator
provides a practical solution for the problem. By setting up Virtual Desktop, you can set your Windows to work in a much higher
resolution than your monitor can support while setting your monitor working at a low resolution.
In a Virtual Desktop environment, you can see only a portion of the Windows desktop at one time. You can either use the mouse to
move the viewpoint -- your monitor screen, or you can freeze your viewpoint and use another program -- "Virtual Desk," provided
together with this program, to control your viewpoint position in the Virtual Desktop environment. Next is the procedure to setup the
Virtual Desktop Environment:
Step 1.Check the check box "Virtual Desktop Enable" first.
Step 2.Use the combo box "Virtual Desktop" to choose a resolution for your Virtual Desktop. This resolution is only limited by
the memory on your Graphics Accel-erator board. The setup program is designed with this factor in mind. You can
select any number provided by the program safely.
Step 3.Use the combo box "Viewport Size" to choose a display mode for
your monitor -- a resolution and refresh rate combination. This is the
actual resolution and refresh rate that your monitor will work on.
The setup program has a few default display modes. If those default
display modes do not satisfy your requirement, please refer to Define Viewport Mode for defini-ng your own Viewport modes.
Step 4.Use the combo box "Color Depth" to choose a color depth. For most
software or applications, 256 colors will be a good choice. If you
need to display real life video or photo, you may need 64k or even
16.7 million colors.
IGA1682 PCI VGA
29
Step 5.Use the combo box "Font Size" to choose either small font or large font for your system. For 640x480 resolution, you
should use small font. For 1024x768 above, you should choose large font. For 800x600 resolution, you can choose
either small font or large font.
Step 6.Click the button "OK" to Accept Selection.
Accept Selection
When you finish your setup, you can simply click on the " OK" button to accept your selection. The setup program will modify
system.ini and win.ini files in your Windows directory (the driver and other font files should already be copied to your system by the
installation program).
If you are running virtual desktop, you can use the setup program to switch your Viewport from one resolution to another on the fly. You
do not need to restart your Windows system.
If you are setting up your graphics accelerator without using virtual desktop, or changing colors, font sizes of your virtual desktop, the
setup program may need to restart the Windows system.
Define Viewport Mode
The button "Define Viewport Mode" will bring you another dialog window to assist defining
Viewport modes for your virtual desktop.
The left list box of the dialog window has all the modes available for IGA graphics
accelerator. In the right list box are the modes you defined for your Viewport.
To add a mode to your Viewport modes, click on an available mode in the left list box.
Then, click on the button " Add >>". If the same resolution has already been defined, the
IGA1682 PCI VGA
30
higher refresh rate will replace lower one. To remove a mode from your Viewport modes, click on a mode for your Viewport on the right
list box. Then, click the button " << Remove".
To make sure that your monitor works for a specific mode, you can click a mode either in Available Modes or in Your Viewport Modes
list box. Then, click the button "Test". Your monitor will be set to that mode for a few seconds. In this way, you can easily verify that
your monitor is working at the desired mode. When you finish defining Viewport modes, click the "OK" button to go back to the main
dialog window. The defined modes will be available in the combo box "Viewport Size." But, only those Viewport resolutions that are
less or equal to the Virtual Desktop resolution will be displayed in that combo box. If you want to choose a higher resolution for your
Viewport, just increase the resolution of your Virtual Desktop.
Display Screen Centering
The Screen Centering provides an easy way to adjust the position of your screen on the monitor. The program not only centers the
screen, it will also record the position you have set into a file. This is particularly useful when using virtual desktop to switch from one
resolution to another resolution. If you preset all display modes for your virtual desktop Viewport, you do not need to physically adjust
your monitor every time you switch resolutions.
To move the screen, you can click on either arrow buttons.
Clicking the center button will bring the screen back to the starting position before you
enter the program.
Moving the screen beyond certain point might cause your monitor to lose sync. When this
happens, you can either hit the <ESC> key to abort the program and bring back your screen,
or simply wait for the time-out. The time out count down will start whenever you click an
arrow button. The count down lasts for about 6 seconds. During the count down, if you click
on any arrow buttons again, the count will restart from the beginning.
IGA1682 PCI VGA
31
Virtual Desktop Control
The program "VD Control" (Virtual Desktop Control) is a convenient tool for virtual desktop users to do their daily work in virtual
desktop environment.
When the program starts, it will freeze the Viewport even you did not set your Viewport to be freeze. By moving the small red rectangle
in the program control panel, you can easily move your Viewport around the virtual desktop. In contract with regular way of using
mouse to move the Viewport, this will provide more stabilized screens and an easy, rapid solution to move your screen viewport.
If you click on the system menu of the program control panel, you can get a menu of "Switch
Resolution" and its sub menu. Using this menu, you can switch your Viewport from one resolution
to another on the fly.
Please note that this program has to be running exclusively with the program "IGASetup". In other
words, before you execute this program, you have to quit the IGASetup program. Before you run
the "IGASetup" program, please quite "VD Control" first.

3. Gamma Correction
IGA1682 PCI VGA
33
As we know, the characteristics of CRT monitors are not linear regarding to its signal voltage. Therefore, the video signals must be
modified before transmission. This is the so called "gamma correction." Normally, the output of your display should already been
corrected to roughly close to a linear characteristics. But, there are so many different makes of monitors that you may need a tool to fine
tune your monitor's Gamma.
To adjust monitor Gamma, you need select the Color Ramps with Dithering test pattern first.
Then, place the mouse cursor over the Gamma slider button. Press and hold the left mouse button while moving the slider right or left
to increase or reduce the monitor Gamma. From the curve above the color buttons, you can see that increasing Gamma will increase
contrast in the dark tones of the display while decreasing contrast in the brightness tones.
Adjust the Gamma slider to the point that the small dithered area in the test pattern are closely matching the background color.
Click "OK" button to preserve your setting.
The Gamma of three color components -- red, green, blue, can be adjusted separately. The only thing you need is to push down a color
button, and follow the above procedure to adjust Gamma for that individual color.
