- Graphics Adapter Device Drivers (GRADD)
- ───────────────────────────────────────
-
- 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:
-
- Sniff 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.
