I currently work on Vesa true colour modes. My progs work fine with W9x, but XP is a pain in the ass ! The screen is messed up when I leave QB to get back to XP.
My new machine is a Compaq EvoN1050v, 24 bits graphic card, running XP Pro.
Will it help if I create a plain Dos partition with a plain Dos, or does the problem come from the hardware ?
I don't think it's the hardware... how messed up does the screen get? Because you should change back to SCREEN 0: WIDTH 80, 25 at the end of your program, just to see if that'll help.
xp gets very piss-strict with vesa. it doesnt support it very well, and in a lot of cases, not at all.
You know, XP doesn't like DOS at all...
I always come back from the SVGA modes with a Screen 0, width 80,25.
I doesn't help here, the screen is messed-up with parasites, and F doesn't help neither to refres the screen. I have to reboot before getting back to a normal view.
I can't even run QB directly from XP: the only way to run QB without too many problems is to open a dosshell, set it full screen, and call QB from the dos command line...
It works, but the screen is still messed up when I get back to XP...
Check for an updated driver for your video hardware. It solved for me a silly problem at returning to text mode. (I don't know nothing about XP)
I got that from the HP ATI download center... I installed it, but it doesn't do much
just think about how much DOS compatibility you'll have with windoze Longhorn.
Hint: It is popularly believed that the Romans didn't have a number for it.
I even read that Microsoft is preparing to compensate even more for the awesome speed of new computers. They're going to make transparent window overlays, let you angle your windows, even RESIZE your windows, just like DOS screens today. Except that they will be resizing vector boxes, not pixels, so that it will look the same on a smaller OR larger resolution. (and they're doing it in Office 2000 now) Wow, CRISP letters with "SMOOTHFONTS" EASIER TO READ, INCREASES PRODUCTIVITY!! But it's incredibly fast and there was "almost no slow down" while all these was happening. On a high-end +3000 mhz machine.
Holy cow, batman, almost no slow down on the latest +3000mhz machine with what, 1024megs? You've got to be kidding me.
