2.2 Installation Procedures

To install the adapter into your system, follow these steps:

1. Turn OFF all power to your system, including any peripherals

(printer, external drives, modem, etc.).

2. Disconnect the power cord and the monitor cable from the back of

the computer.

3. Unfasten the cover mounting screws on your system and remove

the system cover. Refer to your system user manual for instructions and to determine the location of the mounting screws.

4. Remove any graphics adapter that already exists on your

motherboard. Start by removing the screw that holds the adapter retaining bracket in place (keep this screw, you will need it later). Then, gently pull straight up on the adapter card itself, and remove it from the motherboard.

5. If appropriate, you can use the expansion slot left vacant by the

existing graphics adapter you just removed. Otherwise, select an appropriate AGP bus expansion slot for the new adapter. Refer to your computer system manual for the location of the AGP bus expansion slots. Remove the retaining screw that holds the slot cover in place. Slide the slot cover out and put the screw aside (you will need it to secure the adapter). If you just removed an existing graphics adapter and are not going to use that expansion slot, you can install the slot cover you just removed from the unused expansion slot to cover the open hole.

6. Install the adapter. To install the adapter in the selected

expansion slot, carefully line up the gold-fingered edge connector on the adapter directly above the expansion slot connector on the motherboard. Then press the adapter into place, completely, using only as much pressure as is safely necessary. DO NOT USE excessive force. Use the (remaining) screw you removed to secure the adapter retaining bracket in place.

7. Replace the computer cover. Secure the cover with the mounting

screws you removed in Step 3.

You have now completed the installation of your new graphics adapter on your system. Before you use the system, however, please refer to the following sections, “Connecting the Display”.

3.3.2.1 Virtual Screen

Virtual screen allows the monitor to display the information of a larger screen within the physical borders of the monitor. On some monitors the display fonts at higher resolutions, such as 1024x768, may be too small to read. If virtual screen is enabled for 1024x768 resolution, the display font will be larger in 640x480 resolution or 800x600 resolution; however, the information displayed will be that of 1024x768 resolution. To enable virtual screen:

þ 1. SET UP the Trident display at a higher resolution, such as

1024x768.

þ 2. SHUTDOWN the system and then re-start the system. þ 3. GO into the Video configuration folder and CLICK on the

“Display Setting“ object to select the screen resolution page.

þ 4. CHOOSE a smaller resolution such as 640x480 and CHECK

the line that says "Virtual Screen On".

þ 5. CLICK on the ‘Set‘ button and the screen will automatically

be set to physical screen size of 640x480 with virtual screen size of 1024x768.

To return to base mode from virtual screen:

þ 1. SELECT base mode screen resolution. þ 2. SELECT ‘Set’.

Notes:

1. To activate virtual screen, color depth has to be the same for both the

physical screen and virtual screen.

2. Virtual screen size has to be larger than physical screen size.

3. If you change the resolution, you must reboot OS/2 to have the

changes take effect.

4. If you decide to change your hardware system configuration, such as

upgrading video memory or system memory, you should a) Change the resolution to VGA.

b) Change the hardware configuration. c) Re-install the Trident OS/2 Display Drivers.

3.4.1.1 SVM.EXE

SVM is a menu-driven program designed to select and test all video modes available to the adapter.

HOW TO USE SVM

The SVM program can be executed in either of two ways: by calling up the menu and selecting from the menu choices, or by entering the desired mode directly with a specific command line.

HOW TO USE SVM FROM THE MENU

þ 1. SWITCH directory to “X:\TVGAUTIL\UTILITY” where X: is

the drive where the Trident Utility and DOS Application driver files have been copied.

þ 2. TYPE SVM to call up the menu (see Figure 3-27).

Figure 3-27.

The top bar shows the available color depths. This is traversed through by use of the right/left arrow keys.

The program provides all the different resolutions supported by the chip under each color depth. These resolutions are traversed by the up or down arrow keys. The graphics adapter can be tested for each resolution/ mode by first high-lighting the selection (e.g. 1024x768-256 colors as shown in Figure 3-27) by use of the arrow keys, then pressing the F5 key.

The graphics adapter can be run at a selected mode by first selecting the mode and then pressing ENTER.

HOW TO USE SVM FROM THE COMMAND LINE

The SVM program may be used to select a mode directly from the command line following two simple steps:

þ 1. SWITCH directory to “X:\TVGAUTIL\UTILITY” where X: is

the drive where the Trident Utility and DOS Application driver files have been copied.

þ 2. TYPE in SVM [mode number] and PRESS ENTER.

For example, to run the graphics adapter in mode 62H, the command line would be:

SVM 62 <ENTER>

3.5 Optional TV Out

In Windows 95, use 'Television' control page and 'Display Device' control page to select television only features in display properties once the display driver for Windows 95 has been installed. The 'Television' control page allows the user to select 'Underscan' or 'Overscan', to select 'Interlaced' or 'Non-interlaced', to adjust the 'Screen Shift' of the television display horizontally and to select the degree of flicker reduction under Advance control button. The 'Display Device' control page allows the user to switch from color monitor to TV as the default display device and vice versa.

In Windows 3.x, use the Display Control program in Display Driver and Utility Program Group to access TV display features and to switch from color monitor to TV as the default display device and vice versa. The Display Control program allows the user to select Underscan or Overscan, to select interlaced or non-interlaced, to select degree of flicker reduction and to adjust screen shift both horizontally and vertically.

In DOS, a TSR program "TVDISP" is available in the directory of "X:\TVGAUTIL\UTILITY" (where X is the letter of your hard disk drive). This program allows the user to select 'Underscan' or 'Overscan', to select 'Interlaced' or 'Non-interlaced', to switch from color monitor to TV as the default display device and vice versa, to adjust the 'Screen Shift' of the television display both horizontally and vertically, and to contract or expand the size of screen both horizontally and vertically. More information about the TVDISP program is available in the REAME.TXT file of this directory.

Conventional broadcast TV or VCR content provides an "Overscaned" viewing area in order to ensure that the entire visible screen is used. The result is that portions of the image along the border are beyond the physical screen. The actual visual area lost is dependent on the individual TV model. On the other hand, a PC system display content should be within the boundaries of the physically viewable screen. This is called underscan. When the TV is used as the display device in a PC, display hardware needs to control the image generation circuitry to drive the underscan timing to the TV.

Besides generating interlaced timing, hardware may have the option to drive non-interlaced timing to the TV. A non-interlaced display will remove much of the flicker effect but reduce the detail of the image.

The interlaced timing of a TV causes a flickering effect on the screen. Depending on the TV standard and tube phosphor material, the severity of flicker differs from one brand and model of TV to another. Since TV content is almost always full-motion video or animation, flicker is not as noticeable as it is when the screen content is stationary. Flickers are caused by a television’s low frame rate as well as the interlacing of adjacent scans. This flicker is most obvious when a particular scan contrasts highly with the scans directly above and below, such as a black horizontal line on a white background. This type of flicker can be greatly reduced by 3DImàge985's built-in flicker reduction filter.

4. Frequently Asked Questions (FAQ)

Q1 What is AGP and what does it mean? Answer

The Accelerated Graphics Port (AGP or A.G.P) is a high performance, component level interconnect targeted at 3D graphical display applications and is based on a set of performance extensions or enhancements to Peripheral Component Interconnect (PCI). A typical 3D application requires tremendous amount of memory to render 3D scenes. AGP provides a cost-effective way of shifting some of 3D rendering data structures into system memory from frame buffer of 3D graphics accelerator. The 3DImàge985 supports the higher performance 2X or execute mode of AGP which allows data structures to be executed in system memory space without being copied into the frame buffer of 3D graphics accelerator prior to use by the accelerator.

Q2 Why do we need 3D graphics capability in our PC? Answer

3D technology is becoming increasingly important (and common) not only in games, but also in other applications such as VRML, which allows 3D scene descriptions in Web applications. 3D technology is used for image editing, modeling, and an increasing number of in home and business applications. In games, as well as other applications, 3D acceleration not only allows better visual qualities and more realistic scenery attributes than software alone, but it also allows a higher frame rate, which translates into a more interactive experience for the end users.

Q3 What does “Rendering Engine” mean? Answer

“Rendering Engine” generically applies to the part of the graphics engine that draws 3D primitives, usually triangles. In most implementations, the rendering engine is responsible for interpolation of edges and "filling in" the triangle.

Q4 What does the set-up engine do in a graphics controller? Answer

A set-up engine allows drivers to pass triangles in the form of raw

vertex information; whereas, most common designs force triangles to be pre-processed for the rendering engine in terms of delta values for edges, color, and texture.

Q5 Why does a 3D graphics chip need to have both a rendering engine and a setup engine?

Answer

Any “3D application”, a game, VRML, or modeling package, can benefit from 3D rendering. This is especially true of applications that use texturing extensively; because texturing and texture filtering are very intensive operations at the pixel level in terms of CPU operations and demands for memory bandwidth. Without a set-up engine in a graphics controller, the CPU has to calculate the delta values for edges, color, and textures; the drivers need to handle ten (10) times more extensive data. This results in slower 3D pipeline operations between the CPU and the graphics controller.

Q6 If we use powerful CPUs, such as a Pentium™ 200, can a standard 2D graphics card achieve 3D performance?

Answer

Yes and no. Software rendering can take advantage of "tricks" learned by force of necessity through years of trial and error. With such stratagems, the speed of software rendering for simple scenes can approach that of low-level hardware 3D rendering. On the other hand, as scenes become more complex, there are conflicts between using the CPU for high-level game logic, geometry, lighting, and rendering, all of which increase their demands. No current CPU or system can perform advanced quality-enhancements (bilinear filtering and alpha blending) in real time. Even general case texture mapping with RGB lighting is too much for the current CPU generation.

Q7 What does "software 3D" mean ? Answer

Software 3D is generally used to mean using non-specific (2D) hardware in conjunction with the CPU to render for 3D applications. Some of these techniques allow usable 3D applications when highpowered and/or MMX™-equipped CPU's are employed along with special-case software optimization techniques. As stated above, SW 3D can achieve credible results with today's applications, but the rising popularity of good 3D hardware at the consumer price level is

inexorably compelling the public to expect hardware level scene enhancements and frame rates.

Q8 What is “SGRAM”? Answer

Synchronous Graphics Random Access memory (SGRAM) is a new and improved type of memory, custom-designed for graphics use.

Q9 What is the advantage of SGRAM as compared to ordinary DRAM?

Answer

SGRAM is now capable of running at much higher speeds than fast page or EDO DRAM. Also, SGRAM is able to execute a small number of frequently executed operations, such as buffer clears, specific to graphics applications, independently of the controller.

Q10 What is 3DImàge985? Answer

The 3DImàge985 is one of the first of the "second generation" 3D controllers which will catapult 3D applications of all types into the PC mainstream by providing the feature set and performance necessary for compelling 3D applications. It does this by combining proven VGA, video, and graphics acceleration with an advanced 3D rendering core including a set-up engine and a full 3D feature set.

Q11 Why should the customer choose Trident 3DImàge985 over other alternatives?

Answer

As stated above, the 3DImàge985 is second generation. This means that it combines the full feature sets often seen in first generation designs with the essential elements that were missing in those designs:

• High performance 3D achieved by innovative design

• Careful attention to system level integration

• Aggressive use of existing and recently developed technology,

such as single-cycle SGRAM memory interfaces

The 3DImàge985 represents an overall competency in all areas, with excellence in some important ones, such as 3D and video, that make it the best choice on the market today for both consumer and commercial applications.

5. Troubleshooting

The following are some recommended steps to take if the GUI accelerator adapter will not boot or operate properly in your system:

1. Ensure that the monitor or TV brightness and contrast controls

are properly adjusted.

2. Check to see if your monitor or TV is properly connected to the

card. Be sure your monitor's pin definitions match those of your GUI accelerator card (See Appendix B). For TV out, ensure that the composite signal is connected to a “Video Input” RCA jack on the TV (or check the S-video connection). Read the TV owner’s manual to select the proper signal jack for the display.

3. Turn the system on and confirm that the power supply is

operating properly; i.e., that the fan operates and the system power light turns on.

4. Check to see if the card is firmly seated in its AGP bus expansion

slot. It should not be making contact with any other cards in the system.

Note: Turn the system off before adjusting the card.

Problem: Windows hangs up during or after installing a driver.

Solution A: Reread installation procedures to be sure you have installed

the drivers correctly.

Problem: Windows color palette does not look right or colors

changing.

Solution: Most likely a defective RAMDAC, memory chip, clock chip,

or crystal. Contact your dealer to have the problem repaired.

Problem: Can't display certain modes.

Solution A: Run the SVM program (See the User's Guide for more

information on the SVM program). If the SVM program fails, go to Solutions B, and C.

Solution B: Check to see that there is enough memory on the GUI

accelerator to run this mode. For example, to run display mode 79H (1024x768-64K colors, refer to the tables in Section 2), 2 MB of display memory is required.

Solution C: If Solutions A, or B do not resolve this problem, it may be

hardware related. Check the specifications of the monitor.
