    1.5 SELECTING LARGE OR SMALL FONTS FOR WINDOWS


    The selection utility is available for OS/2 Warp 3.0 only.


    

    1.6 NEW FUNCTIONS PROVIDED WITH THIS DRIVER


    Change Refresh Rate on the Fly is available for OS/2 Warp 3.0

    only.  The new utility, located in the Systems Settings, allows the 

    user to change the vertical refresh rate "on the fly", that is, without 

    resetting the operating system or rebooting the system.


    The following procedure will allow you to change the refresh rate for

    your monitor without rebooting the system:


    1.  Double click on the OS/2 System icon

    2.  Double click on the System Setup icon

    3.  Double click on the System icon

    4.  Check to see if the monitor attached to your system is selected

        in the Monitor Box

    5.  Click on down button of the Refresh box and select a refresh rate

        (this refresh rate must be supported by your monitor)

    6.  Click the Test button.  The display will blank momentarily and

        return with a message box

    7.  Click on the YES button in the message box if your screen appears

        OK.  If your display is not readable, press the ESC key to return to

        the original refresh rate setting.


   2.0 COMPATIBILITY

   ________________


    This graphics accelerator driver is compatible with OS/2 Warp.


   3.0 PRELIMINARY STEPS

   _____________________


    The following steps prepare your computer for the installation

    of a new OS/2 graphics device driver:


    1.  You must have OS/2 DOS Support installed in order to install

        this driver.

    2.  If you previously installed SVGA, or any Cirrus Logic Driver,

        you must return to VGA mode before installing any subsequent

        driver.  Please use the procedures in the following section.


   4.0 SETTING YOUR MONITOR TO VGA MODE

   ____________________________________


    Use the following procedures to return to VGA mode.


    o   If you are installing this device driver on OS/2 Warp

        and you do not have a usable OS/2 Desktop, use

        the following procedures to return to VGA mode.

        However, if you have a usable Desktop, it is

        recommended that you use Selective Install to set

        your monitor to VGA mode.


        1.  Turn on your computer.  If your computer is

            already on, press Ctrl+Alt+Del to restart it.

        2.  When a small white box appears in the upper-left

            corner of your screen, press Alt+F1. If you see

            the OS/2 Logo displayed, you must start again at

            step 1.

        3.  When the Recovery Choices screen appears, press V.


        Your video adapter is now restored and can work in

        VGA mode.  If you want to install a new video

        adapter or video device driver, refer to Chapter

        16, "Video Procedures," in the User's Guide to

        OS/2 Warp.




   5.0 INSTALLATION OF DISPLAY DRIVER FROM DISKETTE

   ________________________________________________


     

     To install the Cirrus Logic Device driver from diskette,

     do the following:


     1.  Insert the Cirrus Logic diskette into drive A:

     2.  Double click "OS/2 System" Folder.

     3.  Double click on the Drives icon.

     4.  Double click on Drive A:

     5.  Double click on Install.exe.

     6.  Choose "Install" from the Cirrus Logic Install Program.

     7.  Click OK to let Install identify your graphics hardware and

         memory configuration.

     8.  Select "Yes" to change your display driver settings.

     9.  Select a screen resolution and close System Settings dialog

         box.

    10.  Close down Drive A - Icon View, Drives - Icon View and System

         Setup Icon View.

    11.  Remove the diskette from Drive A:

    12.  Shut down and reboot the system.


    Note:  If video memory size is changed in a system, the

           user must re-install Cirrus drivers (by re-installing

           VGA drivers first, then the Cirrus drivers).  Refer

           to Section 3.0 above.





   6.0 RUNNING IN UNATTENDED MODE

   ______________________________


   Install as follows:


       At the command prompt, type:


       A:] install /r:<path>install.rsp 

           where <path> == floppy or hard drive containing installation 

           media


   The INSTALL.RSP file contains a list of default responses to installation

   options.  These options are the location of drive containing the media, or

   use of an optional log file (for logging the unattended installation).
