  








Graphics Adapter Device Drivers (GRADD)
  컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴?

  OS/2 Warp 4  introduced a new graphics adapter device driver (GRADD)
  architecture that makes it easier to support new hardware as it becomes
  available.  Enhanced PM applications performance can be realized when using
  accelerated GRADD drivers.

  Several new and updated GRADD drivers are included with this package.

      This README file, which is formatted for viewing on your screen.  You
      can:
      -   Use the Table of Contents and page numbers (which appear at the top of
          each page) to help you locate specific topics.
      -   Use the Find option in the Edit menu of the OS/2 System Editor to help
          you locate specific information.
      -   Print the file.


  IMPORTANT

  PLEASE READ THE FOLLOWING TERMS AND CONDITIONS.  YOUR USE OF THE OS/2 GENGRADD
  DEVICE DRIVER INDICATES YOUR ACCEPTANCE OF THE FOLLOWING TERMS AND CONDITIONS:

  o   YOU MUST BE, AND YOU AGREE THAT YOU ARE, A PRIOR LICENSEE OF OS/2.
  o   YOU MAY MAKE COPIES OF THE OS/2 GRAPHICS ADAPTER DEVICE DRIVERS (GRADD)
      EQUAL TO THE NUMBER OF LICENSED COPIES OF OS/2 YOU POSSESS.
  o   ALL OTHER TERMS AND CONDITIONS OF YOUR OS/2 LICENSE AGREEMENT APPLY TO
      THESE OS/2 GRADD DEVICE DRIVERS; HOWEVER, THIS DOES NOT EXTEND ANY
      WARRANTY OUTLINED IN SUCH AGREEMENT.



























                                                                          Page 1
















  SUPPORTED FEATURES
  __________________

  The GRADD device drivers provide seamless support for accelerated/
  unaccelerated display graphics and advanced color depth and resolutions. They
  conform to the OS/2 32-bit flat memory model and are designed to function as
  32-bit Presentation Manager* graphics display drivers under the OS/2 32-bit
  graphics engine.

 



  SUPPORTED RESOLUTIONS

  Supported resolutions and color depths are adapter dependent and will vary
  based on video memory and adapter implementation.


  COMPATIBILITY
  _____________

  These graphics drivers are currently compatible with OS/2 4.0


  with Fixpak 5 or later.  Since Fixpak 5 or later enables the use of
  GRADD drivers, you should restore your system to VGA before uninstalling
  to a fixpak level that is prior to Fixpak 5.
























                                                                          Page 2





  PRELIMINARY STEPS
  _________________

  1.  If you previously installed SVGA support, return to VGA resolution using
      the procedures in "Setting Your Display to VGA Mode" later in this README
      before you install this driver.


  INSTALLATION
  _________________

  INSTALLATION FROM DISKETTE
  __________________________

  To install the GRADD Drivers from diskette, do the following:

  1.  Insert the GRADD driver diskette into drive A (or any other diskette
      drive).
  2.  Open an OS/2 full-screen or OS/2 window session.
  3.  At the OS/2 command prompt, type the following command to copy all
      necessary files to the OS/2 drive:

      SiSINST
     
      Then press Enter.


  4.  When prompted to do so, remove the diskette from drive A, perform a
      shutdown, and then restart your computer.
  5.  When the system reboots, do the following:
                                                               
       a.  Open the OS/2 System folder.
       b.  Open the System Setup folder.
       c.  Open the System object.
       d.  When the Settings notebook appears, select the Screen tab.  Then go
           to Screen page 2.
       e.  On Screen page 2, select your display from the display list.  If your
           display does not appear in the list, select Default.
       f.  Return to Screen page 1 and select a resolution.
       g.  Close the Settings notebook.
       h.  Perform a shutdown and restart your computer.

  NOTES:
  1) During the installation of this driver, DISPLAY.LOG and DSPINSTL.LOG
     files are created in the OS2\INSTALL directory.  These files identify the
     OS/2 system files that were updated and indicate whether the installation
     was successful.  The contents of these files might be useful if you need to
     report an installation problem to IBM.

  2) Installation of the GRADDs uses the Dspinstl utility shipped with OS/2 4.0.
     This utility can fail if if finds a "*.dsc" file which is not a dspinstl
     description file.  During testing, it was found that installation of
     SystemView for OS/2 client may leave behind a file called "commonag.dsc" on
     the root of the bootdrive.  This file is not a Dspinstl description file
     and will cause Dspinstl to fail.  If you have this problem, simply rename
     or delete the problem file.  If an incorrect description file is
     encountered, it will be noted in the above log(s).

                             




                                                                    Page 3
 













  SETTING YOUR DISPLAY TO VGA MODE
  ________________________________

  Use the following procedures to return 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-hand corner of your
          screen, press Alt+F1.
      3.  When the Recovery Choices screen appears, press function key F3.

      Your display adapter is restored and can work in VGA mode.  If you want to
      install a new display adapter or video device driver, refer to the User's
      Guide to OS/2 Warp.
