How do I get DOS at higher than 640x480?

Specs: MS-DOS 6.22
I'm using virtual machine software on an old laptop, and in the software I'm running a virtual machine which has MS-DOS 6.22 and Windows 3.1 in it. The display adapter that the software emulates is an S3 Trio 32 or an S3 Trio 64 (I'm not sure which since they use the same driver), and I got the drivers for it in Windows 3.1, and set it to display at 1024x768, as that's the resolution of the laptop's display. But, I was wondering if I would be able to get DOS text mode to display at 1024x768. I've seen people do higher than 640x480 on certain video cards, so is there a driver you can get for the S3 Trio 32/64 that allows you to do that?

What virtual machine are you using? It's likely that would be the determining factor as to the resolution of whatever runs beneath it....

I'm running Connectix Virtual PC 4.0 under Mac OS 9.2.2 on a 600MHz iBook G3 with a screen resolution of 1024x768. I got the laptop recently and figured that it would be fun to run virtual machine software on it.

Even though this discusses Win95, Win3.x settings should be similar...

The article is showing how to get higher resolutions in Windows 95, which the software came pre-installed with, and had all the drivers. In Windows 3.1 changing resolution is completely different, instead of being able to change it on the fly once the driver is installed, you would have multiple different drivers for a video card, each with it's own resolution and color depth, and if you wanted to change the resolution and color depth in Windows 3.1, you would reinstall the driver. Plus, I'm trying to figure out how get MS-DOS 6.22 at 1024x768 instead of 640x480, not Windows 3.1.

DOS doesn't have any type of resolution settings of it's own. Games that run under it have their own drivers for whatever video card exists.

Yes, I know that DOS doesn't have resolution settings by default, and the DOS games have their own drivers for different video cards, but I've seen people get DOS text mode with more columns and rows by using special drivers for the card they have in their system, such as with this video card featured in this video by LGR, where you could get 132 columns with 43 rows, instead of 80 and 25.

Have you tried using the DOS command "mode"?

There's another VMODE.EXE on disk download APR00089 here:

It's larger than the one in riider's link. It may be another version or some other file altogether.
