I read in the Reference Manual that I should be able to render in the background of OS2 while I use other programs. However, I can't get this to work. I've tried changing the desktop screen resolution, rendering from the dos command line, and using slave mode, but the background rendering still hangs until I return to the 3DStudio program. I use an IBM clone PC with a Pentium CPU 90, and a VI-720 PCI VGA graphics card (Cirrus CL-GD5434 chip) with 2MB ram. I've been trying to overcome this problem for months. Thank you for your attention. Peter Landeck (Authorization code 8B092D29)

Look at file 3dsos2.zip in library 6 (HWare/OpSys). This file describes the various settings needed to allow 3ds to run under os/2. LAM

Thank you for the reply Larry; however, after making the various setting changes 3ds4 will still not render in the background on this computer. I wonder if it is the graphics board that I use? The config.sys shown in the .zip file doesn't work for my cirrus chip 543x based graphics board. Does your machine render in the background, and if so what graphics board do you use? I didn't quite understand the following recommended setting: Dos_shell=C:\4dos\4dos.com c:\4dos @d:\3ds3\4dos.ini should I substitute my C:\dos6\dosshell.ini for "4dos.ini", and command.com for "4dos.com"? -Peter Landeck

The exact contents of the config.sys file is dependent on your machine configuration. I would stay with your original config.sys, and look at the lines at the bottom of the config.sys file from the .zip file dealing with svga. It's been a while since I've run 3ds under os/2, but as I remember it, the only real change in the config.sys file was adding the parameter "/bgexec" to one of the device lines dealing with the svga device driver. I've never tried a Cirrus chip set. The ones I've gotten it to work with are a diamond speedstar and an ATI Graphics Ultra. Have you tried using the null video driver yet? It's at the bottom (I think) of the Vibrant list. Using this driver causes 3ds never to go into graphics mode. You have no idea if anything went wrong, but if desparation calls… LAM
