It's fairly easy to reverse the video on a CGA computer (laptop or otherwise). All that you have to do is write a different attribute byte to every character of the display once. This will reverse the display and, generally (in terms of DOS character programs) it will remain reversed unless another program writes directly to video memory. I wrote a program to do this, and I probably still have it. If you will E-Mail me directly, I will send it to you if I can find it. You can run it in autoexec.bat, or manually, either one.
