For people trying to help Kevin get DOS Window to work, here is the URL of the computer
http://www.blondeguy.com/computer/quebopeep.htmlNormally DOS Full Screen would work on this computer. But I am not a DOS user, so I have little to contribute beyond what Arca Noae gives me.
The DOS compatibility will improve in ArcaOS 5.1. The improvement will not easily install on ArcaOS 5.0. If you are a DOS user, you have something to look forward to.
Of the suggestions seen so far, I like installing an old (poster says 10 years old, but I think he meant 20) ATI card. This computer is the last one to have PCI bus, so an old video card is a possibility.
If this can be solved by better DOS settings, then I'd like to see that.
