- OS/2 2.0
- RESTORING VGA VIDEO SUPPORT
-
-
- Video support for many different video cards has been included in
- the OS/2* 2.0 code. The original code only supported the Video Graphics
- Array (VGA) on the desktop for most Super VGA cards. Later releases of
- the OS/2 2.0 code provides support for Super VGA on the desktop for some
- video cards with the Tseng ET4000 chipset. Several other modes of video
- support are also available including 8514 video support and Extended
- Graphics Array (XGA). It is important to remember that the PC must have
- the proper hardware installed in order to take advantage of the advanced
- video support. If the video card only supports VGA resolution and you try
- Selective Installing XGA, then the system will crash. Below is a set of
- procedures for manually restoring the OS/2 2.0 VGA support in the event
- a user chose an unsupport video resolutions during the Selective Install.
-
-
-
-
- I. Code Level XR02000 (GA) from the shrink wrapped box.
-
- 1. Boot the machine from the OS/2 2.0 Installation Diskettes.
- A. Insert Installation Diskette into the A: drive and then turn the power on.
- B. After the system has completed reading the Installation Diskette, you will
- then be requested to insert the Diskette 1. Insert the Diskette 1 and
- press the Enter key.
- C. When the grey 'Welcome' screen appears press the Esc key and the system
- will respond with an A:\ prompt.
-
- 2. Restore the DISPLAY.DLL file.
-
- There are two ways to restore the DISPLAY.DLL file. The first procedure is
- to copy the backup of the file. The second is to manually unpack the file
- the Installation Diskettes. The second procedure should be used if
- DISPLAY.BAK is not located in the C:\OS2\DLL subdirectory.
-
- Procedure 1.
- Copy the DISPLAY.BAK.
-
- A. Type the following:
- COPY C:\OS2\DLL\DISPLAY.BAK C:\OS2\DLL\DISPLAY.DLL (Press Enter)
-
- Procedure 2.
- Unpack the VGA drivers from the OS/2 2.0 Installation Diskettes.
- If OS/2 2.0 was installed on another partition other than C:, then susbstitute
- C: with the appropriate drive letter in the statments below.
-
- A. Remove the Diskette 1. from the A: drive and insert Diskette 12.
- B. Type the following: C: and press the Enter key.
- C. Type the following: CD OS2 and press the Enter key.
- D. Type the following: UNPACK A:VGA C: and press the Enter key.
- E. Type the following: CD \ and press the Enter key.
- F. Type the following: COPY C:\OS2\DLL\VGA.DLL C:\OS2\DLL\DISPLAY.DLL
- and press the Enter key.
-
- 3. Restore the CONFIG.SYS file from the backup copy.
-
- A. Type the following: COPY C:\OS2\INSTALL\CONFIG.SYS
- and press the Enter key.
- B: The lines listed below should be listed in the CONFIG.SYS. To view the
- CONFIG.SYS, type the following: TYPE CONFIG.SYS and press the
- Enter key. Press CTRL-S to pause the scrolling of the screen. Press
- CTRL-Q to continue the scrolling. To print the CONFIG.SYS, type the
- following: COPY CONFIG.SYS LPT1 and press the Enter key.
-
-
- DEVINFO=SCR,VGA,C:\OS2\VIOTBL.DCP
- SET VIDEO_DEVICES=VIO_VGA
- SET VIO_VGA=DEVICE(BVHVGA)
- DEVICE=C:\OS2\MDOS\VVGA.SYS
-
- or
-
- DEVINFO=SCR,VGA,C:\OS2\VIOTBL.DCP
- SET VIDEO_DEVICES=VIO_VGA
- SET VIO_VGA=DEVICE(BVHVGA, BVHSVGA)
- DEVICE=C:\OS2\MDOS\VSGA.SYS
-
-
- 4. Modify the CONFIG.SYS to halt the any application from restarting
- at bootup.
-
- A. If applications where running during the last shutdown they will
- normally restart when the operating system is rebooted. To stop
- these applications from reloading during bootup, execute the following
- command to modify the CONFIG.SYS by adding a line at the end of the file.
- This line can be removed after OS/2 is up and running by editing the
- file with the System Editor.
-
- ECHO SET RESTARTOBJECTS=NO >> CONFIG.SYS (Press Enter)
-
-
- 5. Restore the WIN.INI file from the backup copy.
-
- A. Type the following:
- COPY C:\OS2\MDOS\WINOS2\WIN.BAK C:\OS2\MDOS\WINOS2\WIN.INI
- and press the Enter key.
-
-
- 6. (Optional) Restoring the INI files.
-
- A. If you did not preform a proper Shutdown after the Selective Install
- completed then it may be necessary to rebuild the INI files and run
- CHKDSK to insure there is not any corruption on the hard drive. See your
- Installation Guide pages 75-77. You should attempt the CHKDSK prior to
- recovering the INI files. NOTE: If you follow the procedures for
- Recovering the User INI Files, you will loose all of the customization
- made to the OS/2 Desktop.
