Abstract: OS/2 VIDEO CORRUPTION in TEXT MODE USING VGA DRIVER

SYMPTOM:

Part of text screen illegible in OS/2 in full-screen text mode. (No problem in GUI mode.)

Customer has not installed S3 video driver, or has disabled the S3 driver with ALT-F1 or a boot diskette.

PROBLEM ISOLATION AIDS:

The system is one of the following Netfinity servers:
- a Netfinity 5000 server, Type 8659, any Model.
- a Netfinity 5500 server, Type 8660, any Model.
- a Netfinity 5500-M10 server, Type 8661, any Model.
- a Netfinity 7000-M10 server, Type 8680, any Model.
The system is configured with OS/2 Warp Server 4 SMP.
OS/2 is configured with the Standard OS/2 VGA Video Device Driver for the S3 Adapter.
OS/2 is not using the SVGA driver and does not have FixPack 35 or later installed.

FIX:

Installing the S3 video driver will eliminate this problem in normal operation.
The driver is located on the "Netfinity 5000 / 5500 / Netfinity 5500 M10/ 7000M10 S3 Trio V2/GX device driver diskette for OS/2" 24L8036.EXE located on the IBM web site at the following URL:

If the standard OS/2 VGA driver is still desired over the S3 video driver, eliminate the problem
by either of the following two methods:

Method 1) Install FixPack 35 or later for Warp Server.
Copy the BVHSVGA.DLL from the S3 diskette mentioned above to the \OS2\DLL directory.
Edit OS/2's CONFIG.SYS and add the text ",BVHSVGA" to the "SET VIO_VGA" statement
(if not already present) as as in the line below:
"SET VIO_VGA = DEVICE(BVHVGA,BVHSVGA)"
-- OR --
Method 2) Install the "VIDFIX.EXE" executable (per the README2.TXT file located on the above mentioned diskette).

If video corruption occurs when using the ALT-F1 command prompt option, one of
the above methods must be used to update the CONFIG.X file in the \OS2\BOOT directory
(as in the config.sys installation).
Please refer to the README2.TXT on the S3 driver diskette for information about using "VIDFIX.EXE".
