I mean, not a small window in the middle of the screen, and the rest ist ""black border"". I want a stretched Full-Screen mode. Some further ideas on that topic: I don't think that it's possible to do in an easy way. Correct emulation of DOS mode in Full-Screen I mean. That is why: To emulate DOS Text-Mode, you need to emulate either 720x480 (I think) resolution on host, or Text-Mode on host. In Windowed mode, emulating 720x480 window is not a problem (that's what VirtualBox does, but *it is* a problem in Full-Screen, because VESA standard has no such mode. Of course it may be possible to emulate it via Text-Mode on host, but it has two problems: 1. not all hosts support text-mode (Think of Linux with fbdev enabled) 2. I don't think that VirtualBox BIOS/VideoBIOS is able to translate guest's text-mode into host's text-mode. ...so improving VirtualBox BIOSes might be required, as well as patches to Linux fbdev driver to allow switching into hardware text-mode. (or simply ask the user via VirtualBox Documentation to disable fbdev driver when running Linux host). On Windows host, there is no fbdev problem. Something similar to the Linux fbdev problem also exists for Mac hosts. Currently VirtualBox (and other virtualizers) have ugly approximation of DOS mode in Fullscreen. -Technologov, 30.11.2007." enhancement closed GUI VirtualBox 1.5.2 fixed other other
