"Generic" 800x600 16-color 32-bit OS/2 2.x SuperVGA Display Driver
February 15, 1993
This package contains an alpha level driver for 32-bit "generic"
800x600/16 Presentation Manager support. There is NO "SEAMLESS"
WINDOWS (WIN-OS/2) SUPPORT in this driver. "Seamless" support will
appear in a subsequent release.
Before installing the driver files:
1. Make sure that you have the 32-bit graphics engine installed
(OS/2 2.0 with Service Pak or OS/2 2.1 Beta or later). To
determine your OS/2 release level, issue the command:
from any OS/2 command line prompt. OS/2 2.0 release levels
prior to 06055 cannot use this driver.
2. Make sure that your OS2.INI is set up for 32-bit IBMVGA32.
(If you are currently running any 32-bit PM driver,
2a. If the file \OS2\SVGADATA.PMI does not exist, go to a
full screen DOS session and issue the command:
If the \OS2\SVGADATA.PMI file is not then created, you will
probably not be able to use this driver.
To install IBMDEV32.DLL and IBMVGA32.DLL:
3. Create a new directory (e.g. \Display) and place the
IBMDEV32.DLL and IBMVGA32.DLL files in that directory.
Edit your CONFIG.SYS to place the name of this new
directory in LIBPATH, ahead of the directory containing
the original IBMDEV32.DLL and IBMVGA32.DLL files. For
example, if your LIBPATH line in CONFIG.SYS reads:
change it so that it reads:
(assuming that C:\Display is the directory containing the
new IBMDEV32.DLL and IBMVGA32.DLL files). Keep a backup
copy of the old CONFIG.SYS. Reboot.
Should you need to revert to the original CONFIG.SYS, simply
boot OS/2 from diskette. To do so, insert the OS/2
Installation Diskette in Drive A and reboot. Insert Diskette
1 when prompted, then press ESC when prompted. You will be
presented with an OS/2 command line from which you can make
the necessary restoration.
The full source code to this driver is included in the OS/2 2.1 Device
Driver Kit CD-ROM. It is simply a makefile change from the VGA32 driver!
Just change the two makefile instances of DSCAN_CNT from 480 to 600.
Recompile, and you have this driver.
Please, if you are at all interested in OS/2 programming, join the
Developer's assistance program and get this CD! Considering that most
hardware companies have 0-1 people working on OS/2 devices, the online
community can make a dramatic difference in the amount of OS/2 support

OS/2 2.1 DEVICE DRIVER DEVELOPMENT KIT (DDK) CD-ROM AVAILABLE
This DDK, which replaces previously distributed Display and SCSI Device
Adaptation Kits, is a release of over 50MB of full function source code,
build tools, test tools, and on-line documentation for several OS/2 2.1
device drivers. It includes source code for PM display drivers, virtual
video drivers, base video handlers, printer, DASD, SCSI, CD-ROM, and
mouse drivers. Source code for WIN-OS/2 seamless display drivers is
The information and code on this DDK will be updated and made
available on a DDK in approximately three months and be available
through a subscription service.
o CD-ROM Player
o The DDK is intended for use on IBM OS/2 2.0 with the OS/2 2.0
Service Pack (XR06055) or later releases. Use of this DDK and
its associated utilities on a system earlier than OS/2 2.0 and
the Service Pack may produce unpredictable results.
o It is recommended that developers have the OS/2 2.0 Toolkit
installed on their system so the 2.0 kernel debugger can be used.
o If you are developing video drivers and you require the WIN-OS/2
seamless supplement, you are required to have licenses to use the
Windows** 3.0 and Windows 3.1 DDK.
o For some drivers, Microsoft* C 6.0 is required.
o For some drivers, Microsoft MASM 6.0 is required.
o Adobe Systems files included in the DDK must not be changed.
Persons changing these files are subject to legal action by
the Adobe Corporation.
The DDK includes an installation program that permits you to selectively
install device drivers. After selecting one, more, or all device
drivers, the program informs you of the disk space required and how much
available space you have. The program will not copy drivers onto your
system unless it detects you have enough room for everything you
selected. Regardless of your selections, the installation program will
NOT update your CONFIG.SYS file. Please ignore any messages to the
contrary that may be displayed in this release.
A README.DDK file provides installation information as well as
a detailed description of the DDK.
