"Generic" 800x600 16-color 32-bit OS/2 2.x SuperVGA Display Driver Alpha Release

 "Generic" 800x600 16-color 32-bit OS/2 2.x SuperVGA Display Driver Alpha Release 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:

SYSLEVEL

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,          you're fine.)

2a. If the file \OS2\SVGADATA.PMI does not exist, go to a           full screen DOS session and issue the command:

SVGA ON

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:

LIBPATH=.;C:\OS2\DLL;C:\APP\DLL;C:\;

change it so that it reads:

LIBPATH=.;C:\Display;C:\OS2\DLL;C:\APP\DLL;C:\;

(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 available!

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 available separately.

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.

PREREQUISITES

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.

INSTALLATION

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.
