Hello I would like to know simply, either yes or no, and described clearly about the resolution in DOS. Because I have searched through the site and have not been able to find a simple and comprehendable answer, I am not really a computing professional.
I am running WinME and require a DOS based program which is why im not upgrading to XP. Within WinME I use a MS-DOS, text based program called Concord (or CORD95.BAT, I think).
Now my problem is I have a new LCD screen that only supports 1024*768 resolution.

Is it possible to change the MS-DOS program display to 1024*768?

Editing the program is beyond me and it isnt a program that allows DOS commands where it is possible to enter a command and carry it out, it is, in itself an indipendant, but DOS based, program.

Now, is there any programs/emulators/drivers that can be used to get the program working at 1024*768? I know that my video card is capable of supporting it but I need to know how to set the program to work at that resoulution.

If you can, thanks for your help.
Email or post any infomation you can on the topic and any links to programs or drivers that could work.

P.S. The LCD is a MITAC LCD, quite old, one of the early LCDS made, hence the single resolution.

If your Concord application is text based, the resolution has no meaning as characters are generated on matrix-pixel basis (e.g. 8x8) and can be displayed by whatever phisical screen.

If on the contrary you need to enter graphic mode, plain DOS supports 640x480 VGA resolution and 800x600 SVGA via special VESA drivers.

In DOS drivers are not however part of the operating system, but are related to applications.

By the way textual DOS applications can run under Windows XP if they have clean system calls.

There are emulators (even free ones) to achieve what you want, but they require a skilled user to run properly.

Have you actually tried the program to see if it functions or not?

The text based command prompt is different than the various graphics resolutions - for DOS based applications to use high res graphics you'd need a driver specifically written for that program.

I suspect you're 'overthinking' this (so to speak)

I'm not saying there should be a capital punishment for stupidity, but why don't we just take the safety labels off of everything and let the problem solve itself?

The only way to make it work under Windows ME is to either run it in a DOS window and accept the smaller window and poor resolution of the the characters, or if the program uses standard DOS or BIOS text mode calls and does not do its own Mode set command, to run it after using a MODE set program in full screen, and accept a 128 character by 48 line text display (quite small characters). The program may not even work in 128x48 character mode.

There is a program called MODES.com that when ran will list all of the text and graphics modes that your video adapter BIOS will support. What you would do is run it and and find the 1024x768 graphics modes that your BIOS supports. Usually only one or two. There are other programs that do this, as well as documentation for the video card. Then use a DOS program that is ran in the DOS session before the program loads that sets this mode. If the program does not do its own mode set and is properly written, it will then use a 128x48 text in graphics mode. This will be very slow updates of the screen with small characters, but it will be readable on the LCD display that you have.

If the program does its own mode set, then it becomes very difficult to do what you want to do. There are a few programs that try to handle these cases but the results are not very good. I did some work on trying to write a device driver for WordPerfect 5.1 for DOS to handle LCD screens, but gave up for lack of interest. Same basic problem. I would have to write a special type of driver that emulated text mode to the program but handled the screen in pure graphics mode and use my own Font sets to build text characters on the screen. Major effort not worth my time.

I have some of these mode set programs. But there is no way to know if they will work with your program, without a lot of details on how your program works. And it would take an experienced programmer to find out.
