I'd prefer to use my AutoCAD 13 DOS version within the Win98 platform. The START>SHUT DOWN>RESTART in MS-Dos Mode method is a hassle - I'd like to have the option to ALT -TAB to get there while I remain working with windows(out of environment space is indicated when I attempt to run R13 at the DOS prompt while in Win9. The Pharlap Extender must be configured for AutoCAD R13 DOS to function within the Win98 platform(so I've been told). Please help!
