MORE INFORMATION

Cornerstone Technology has Windows 3.0-compatible video display drivers for its single-page large-screen display. These drivers can be downloaded from the Cornerstone bulletin board service (BBS) or you can order them on disk from Cornerstone. Cornerstone recommends downloading the README.DOC file and reading the instructions before you attempt to download the drivers from the BBS.

NOTE: Cornerstone Technology video display drivers dated before 2/1/91 need to be updated.

You need to add the following line to the SYSTEM.INI file in the [386Enh] section to prevent Windows from using the video extended memory segment that the Cornerstone Technology drivers use.

Cornerstone Dual-Page Video Driver for Windows 3.0 and 3.1

Cornerstone has developed a video driver for the dual-page monitor to run under Windows operating system versions 3.0 and 3.1. The driver, VIDDRVR.SYS version 2.004 (for Windows 3.0) or 2.004a (for Windows 3.1), is loaded in the CONFIG.SYS file.

NOTE: Versions of this driver earlier than 2.004 may cause the following error message after you minimize a Windows-based application:
