  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.

  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 ADAPTERS


  The following accelerated GRADD drivers are provided:


      * ATI Rage II/Mach 64 GRADD       (M64GRADD)

      * Chips & Technology 6555X GRADD  (CHPGRADD)

      * Matrox Millenium/Mystique GRADD (MGAGRADD)

      * S3 864/TRIO GRADD               (S3GRADD)

      * S3 Virge/Virge VX GRADD         (S3DGRADD)


  Also included are generic VGA and SVGA support.


      * Video Graphics Array GRADD      (VGAGRADD)

      * Generic SVGA GRADD              (GENGRADD)


  All of the drivers listed, except for VGAGRADD, require VESA compliant video

  BIOS (Version 1.2 or greater).


  If an accelerated GRADD or PM driver is not available for your adapter,

  GENGRADD may provide UNACCELERATED support for  display graphics at enhanced

  resolutions and colors depths.  GENGRADD will work with most adapters

  that implement VESA compliant BIOS and the performance, which will vary

  depending on system configuration, will not be as good as an accelerated

  driver.


  IBM has tested a number of systems and adapters incorporating the graphics

  devices for the accelerated drivers listed.  Testing was only done on systems

  with PCI bus graphics.


  Current known restrictions are the following:


     ATI Mach 64 ISA Bus adapters currently not supported.


NOTE:


  Testing on ISA bus graphics adapters has worked. However when trying

  to restore your previous "PM" driver, there was a problem in detecting

  the adapter.  Powering off the system to initialize the adapter after

  restoring VGA should solve the problem.


  Future fixes and updates for the GRADD and other video drivers can be found

  via the internet at:


      http://service5.boulder.ibm.com/pspfixpk.nsf


  At the above URL choose All Fix packages and then search for "GRADD".




  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








                                                                          Page 2



  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.



  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:



      SETUP xxx [<SrcPath>] [<BootDrive>] [/u]


       where:

                 xxx is one of:


                 "ATI"   -   ATI Rage/Mach 64

                 "CHP"   -   Chips & Technology 6555X

                 "GEN"   -   GENGRADD Generic SVGA

                 "MGA"   -   Matrox Millenium/Mystique

                 "S3"    -   S3 864/Trio

                 "VGA"   -   VGAGRADD Generic VGA

                 "VIRGE" -   S3 Virge


             [<SrcPath>] is optional (required if next parameter specified) and

                         is the diskette drive


             [<BootDrive>] is optional and is the drive where OS/2 is installed.


             [/u] is optional and is used to indicate unattended install

                  such as for CID installations. A CID response file is

                  not required.


      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:








                                                                          Page 3



       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).



  INSTALLATION IN A CID ENVIRONMENT

  _________________________________


  NOTES:


  1.  Create a directory on the server (i.e. GRADDS). Copy the files from the

      GRADD drivers diskette to the GRADDS directory.

  2.  OS/2 must have been successfully installed on the client using the CID

      (Configuration Installation Distribution) method.


  To install a GRADD driver using CID, use the following information to modify

  your LCU command file.  Example below installs the ATI Rage II/Mach 64 GRADD

  (M64GRADD).


  NOTE:  The following information is meant as a guide.

         Your LCU command file might be different.

  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.
