MS-Dos screen resolution

Microsoft DOS
18 Comments1 Solution16250 ViewsLast Modified:
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?
