Re: Give me my DOS back!

This is a new machine? Then that's the problem. XP Home/XP Pro have no
differences in NTVDM (DOS emulation). When your running in a console
window you are not accessing your video card directly and operating in
text mode which is very compatible with NTVDM. When you run in
fullscreen graphics mode you are accessing your video card directly
which can cause problems.

What kind of video card does this machine have? An Nvidia card?

Also what's your problem with DosBox?

PRE 1987 dos program that is indispensible. Runs on XP professional fine.
Machine fried, new machine came packaged with XP home. Dos program works
except when you hit the F10 button, which should switch you from the text
page to a graphics page, the program crashes. Error message: "The NTVDM CPU
has encountered an illegal instruction CS:9196 IP:e682 OP:ff ff fc ff ee
Choose 'Close' to terminate the application'. the message window allows
cancel or ignore, either of which cancels the application. This is an old
coordinate geometry program that is light years ahead of all the fancy-smancy
stuff they want you to buy, and SIMPLE to run. The autoexec.np file is cool,
compatability options do nothing. Dont want a dual drive system, we switch
back and forth from the DOS to windows application constantly. Looked at
Dosbox, too much hoopla ... there must be a setting I'm missing, or maybe
Home XP just doesnt support the graphics screen.
Any HELP would be appreciated
