On a Compuadd 316 SL Laptop computer, when you operate an MS-DOS application under Microsoft Windows 3.0, 3.0a or 3.1 in 386 enhanced mode and you exit the MS-DOS application, the display screen splits and the machine locks up.


The Compuadd 316 SL Laptop requires the VDDDRAG.386 device driver to run Windows 3.0, 3.0a, or 3.1 in 386 enhanced mode. All new models of the 316 SL are shipped with this driver, as well as Windows 3.0, 3.0a or 3.1, installed.


To verify that the VDDDRAG.386 driver has been installed, check the Windows SYSTEM.INI file [386Enh] section for the following device line:
The driver was shipped on a supplementary disk with some older models of the 316 SL. The VDDDRAG.386 device driver may be obtained from Compuadd technical support at (800) 999-9901 or downloaded from the Compuadd BBS at (512) 250-3226. The file to download is 316SLDRV.ZIP.


The 316 SL is equipped with a screen saving device that is dependent on the BIOS of the keyboard. The saver is not compatible with Windows and should be disabled before running Windows. To disable the screen saver, from the MS-DOS prompt press CTRL+LEFT SHIFT+L. This sequence toggles the screen saver function on and off.

The Compuadd products included here is manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
