MS-Dos screen resolution
Posted on 2007-03-17
I have put together a MS-Dos 6.22 only machine. I am using an old Packard Bell Legend Supreme 1612 with a Pent 150 and 24 megs of ram. I am not putting windows on this machine I want it for older dos stuff only. After installing the operating system and booting to the C:\ prompt I have noticed that my screen resolution is at 720 x 400 (I am using a 17in color monitor). I thought that dos ran in the 640 x 480 resolution as default. This 720 x 400 is very annoying because the screen kinda 'shakes' a bit cause of the odd resolution. If I run something that puts the screen into 640 x 480 the screen looks fine. I have tried two different monitors and the same thing. For some reason the resolution is defaulting to 720 x 400. This machine has built in PCI graphics. its the S3 Virge, but I even tried another video card and still the same thing. I noticed this..when the machine posts the screen resolution is 640 x 480 as soon as that screen goes away and I see the loading MS-Dos screen the resolutin is 720 x 400. I am pretty good with computers but this has me puzzled, tho I did jump in at the time when Windows 3.1 was the main operating system. I did have some experience with DOS but maybe I am missing something. After picking lots of peoples brains I am leaning toward maybe its the PCI graphics? With nothing to drive them they default to 720 x 400?
