A. Using Windows Utility TINSTALL  
---------------------------------  



INSTALLATION PROCEDURE  
=======================  

The Graphic Installation Interface lets you easily install the Trident  
Windows drivers and the Trident Power Management program from within Windows 
by following these steps:  
  
  
1. Ensure that MS Windows 3.1 is up and running properly, using the standard 
   VGA driver.  
  
2. Select the MAIN group in Program Manager.  
  
3. Click on FILE or press ALT + F. 

4. Press "R" to get to the command line.

5. Type in A:TINSTALL and then press ENTER.
     
6. A menu will appear, presenting a choice of Express or Custom Installation.
   
    Express Installation is quick and decision free. Display drivers will be 
    copied into the TRIDENT.AGI directory and Utility files will be copied into 
    the TRIDENT.UTL directory. Once all files are copied, a program group 
    called DISPLAY DRIVER AND UTILITIES will be created.  
  
    Custom Installation allows control over where files are stored and where 
    icons are created. When running Custom Installation, the first dialog box 
    that comes up shows the default directory to which the display drivers 
    will be copied to. This directory name can be changed by clicking on the 
    default name, deleting it and then typing in the desired directory. The 
    dialogue box also displays the available space on the hard disk as well as 
    the total size of the files to be copied. 
    
    Once the desired directory name is selected, the installation procedure is 
    continued by clicking on the box labeled CONTINUE, or by pressing ENTER. 
    The second dialog box displays a summary of where files are stored. Upon 
    selecting CONTINUE, the program will proceed to copy the drivers and 
    utilities files. When all files are copied, the program will present a 
    choice of program groups where the icons will be created. Selection can be 
    made from pre-existing groups (e.g. main, applications, accessories etc.), 
    or the option is there to create a new group name.  
  
7. When all necessary files are copied and a group name is selected, the 
   TINSTALL program will create three icons :  
  
	a. Screen Control       (Used to configure display drivers)  
	b. UNinstall            (Used to delete the installed TRIDENT drivers)  
	c. DPMS                 (Used for power management configurations)  
  
  
  
a. SCREEN CONTROL  
=================  
  
The screen control program supports the following options :  
  
i)      Selecting a Display Driver.  
ii)     Selecting resolution, color depth and font size.  
iii)    Selecting refresh rate.  
iv)     Enable and customize virtual screen features (advanced).  
  
  
To select a display driver, run the Screen Control program by double-clicking 
on the Screen Control icon with the mouse, or high light the icon and press 
ENTER. A window called Display Driver Setup will appear on the screen. This 
screen displays a list of available Display Drivers, the directory in which 
they are installed, date and time of last installation, and if in current use 
or not. Select the desired Display Driver and then click on SELECT. This will 
open the next screen on the Display Driver Setup, which is used to configure 
the Windows display for resolution, refresh rate, the number of colors and 
font size. Selection of these parameters are made by clicking on the 
respective values. To implement the selection, click on OK.

A typical session of setting the display driver is as follows:

	1. Select a color depth.  (e.g. 65K)
	2. Select a resolution.   (e.g. 640 x 480)
	3. Select a refresh rate. (e.g. 72 Hz)
	4. Click on OK.
  
The advanced features provide functions to select  predefined the virtual
screen size. The available predifined virtual screen sizes depend on the 
resolution and color depth selected. The advanced features of the user
interface is accessed by clicking on the box labeled "Advanced", or by 
pressing ALT + D.
 
The features available are:
  
1. Virtual Screen on/off  

      This function turns on/off the virtual screen. When the Virtual Screen  
      is turned on, ( denoted by an X next to "Turn on") a Virtual Screen Map   
      appears on the designated area. This map shows the actual Displayable 
      Area (designated  by the teal colored area), the possible area(i.e. area 
      that can be accessed by Virtual screen, designated by the yellow area) 
      and the invalid area (inaccessible, designated by red). The virtual 
      screen size/shape can be selected by dragging the perimeters of the   
      Displayable area. Once the desired size/shape is selected, the 
      "Alignment Virtual Size" function is used to align/maximize the 
      selection.  Hot keys can be set up to turn on/off the Virtual Screen by 
      clicking on the selection bar next to the function.  
      Once the Virtual Screen has been turned on, predefined virtual screen 
      configurations can be selected.

2. Hot Key

      Predefined key strokes can be set up to perform specific tasks such as
      screen panning and selecting virtual screen resolutions. This is achieved 
      by first clicking on the Hot Key box in the advanced features screen, 
      then selecting the keystrokes in the customization screen.

3. Trace

      Trace function is used to ensure that the active window is always within
      the displayable area.

	


The virtual screen environment can be customized through the features presented 
in the Virtual Screen Advanced Settings screen, accessed by clicking on the box
labeled Customize, or by pressing ALT + S.

Customization features available are:

1. Freeze Screen  

      The Freeze Screen option is used to disable the panning feature, thus 
      giving the illusion of a frozen screen, but keeping other virtual screen 
      functions available.  Hot key functions are available for this feature.  
  
  
2. Linear Frame Buffer Address  
     
      The Linear Addressing driver will automatically detect the system's 
      memory size and set the frame buffer to an unused area above the system 
      memory. The Linear Frame Buffer Address setting is useful for avoiding 
      conflicts with other Windows applications which may use the same linear 
      frame buffer address as the Display Driver. Addresses between 18 and 63 
      Mbytes can be selected. If there is no conflict, the default setting is 
      highly recommended.  
  

3. Border Space  
      
      The Border Space option is used to set up a border (thickness measured 
      in pixels) within the Displayable Area, which is used as a marker for 
      panning the screen. i.e. when the cursor hits against this border, 
      screen pannning occurs.  
 
5. Hot Key  
      Hot keys can be set up to pan the virtual screen left, right, up and 
      down as well as selecting standard virtual screen resolutions.
      The feature has to be enabled first by clicking on the Hot Key box 
      in the Advanced features screen.
  

  
b. UNinstall  
============  
  
The UNinstall program enables the user to delete specific drivers or an entire
driver set. To run the UNinstall program, simply double click on the icon or 
high light the icon and press  ENTER. The first screen will show a list of the 
available display driver sets. To delete the entire set, click on the driver 
set so that it is hi-lighted, then click on the delete button. 
To delete a specific driver within a set, select the set, then click on ENTER. 
A dialogue box showing a list of the drivers will then open on the screen. 
Select the driver to be deleted by clicking on it, and then click on the 
DELETE box to remove it.  
  
  
c. DPMS  
=======  
  
The POWER MANAGEMENT program, in the DISPLAY DRIVER & UTILITIES program group,  
is designed for energy-saving monitors that conform to the VESA Display Power  
Management Signaling (DPMS) standard.   
  
THE USE OF THIS PROGRAM IS NOT RECOMMENDED FOR MONITORS THAT DO NOT SUPPORT 
THE VESA DPMS STANDARD.  
  
The program offers three power-down modes:  
  
    1.  Stand by        (minimum power savings)  
    2.  Suspend         (substantial power savings)  
    3.  Off state       (maximum power savings)  
  
The program monitors for mouse and/or keyboard activity.  When it does not 
detect any activity for a specified delay period, the program signals the 
monitor to enter the selected power-down modes.  
  
The Display Power Management program offers several option to customize the 
DPMS operation :  
  
1. DELAY TIME  
     
     The delay time to enter each mode can be set by entering the value (in 
     minutes ) in the Delay Time parameters.   
  
2. ACTIVITY SELECT  
 
     The Activity Select  option is used to select what activity the program 
     searches for in order to restore the grounded signals. i.e. if both mouse 
     and keyboard is selected, then activity of any of theses interfaces will 
     re-establish the grounded signal.  
  
3. PASSWORD OPTION  

     The Password Option sets up a password to be get back onto the screen.   
  
4. CLOCK  

     Turning on the clock enables the digital count down display. If the Alarm 
     option is enabled, then the last 5 seconds of countdown to Stand by mode 
     is synchronized with beeps.  
  
5. STARTUP ON/OFF   

     This option installs the Display Power Management program onto the 
     Windows Startup file, so that DPMS is active upon entering Windows.  
  
6. SAVE  

     This feature is used to save all the current settings.
