There are a lot of users of DOS, at least here in Russia, but mostly they use ms-dos 6.22. From time to time i see old PCs controlling milling/cutting machines at manufacturing, but they are probably with even older dos (5.0).

 Didnt yet figured out. I have EDID dump, but how can i tell what it means? I will google that.

 Splash-screen (it contains text also) is not scaled, but right after that everything become scaled.

 That's exactly what I think also. But comp manufacturers think that society is not yet ready for fine graphics and 'quadratic quads' :-D :-D :-D
It was noted that Rayer (i read his post about nVidia cards) and Eric Auer solved this problem somehow. I will try contact them.

 THe latter model of this netbook is with 1024x600, so i was a little bit unlucky:-( . Just didnt pay attention to that when was buying:-( .

 Isn't that what i said? Maybe my English suffers, by 'primitive funtcions' i didn't mean any 'humanoid' commands like 'draw_something'. I definitly need to study assembly and vga programming to discuss such things.
