Assembler on NT

[codeman071193]

Hello, does any one know if it is possible to set the video mode in a DOS window when using on an NT PC. Int 10h does not seem to cut it (using A86). The process works great on Windows/NT


Thanks for any ideas

Rod

Try using the VBE:

AH = 4Fh
AL = sub function
INT 10h

Bert, thanks for the answer. And I do find the site very helpfull. It turns out that I was already using that interupt and it won't work on the NT PC I have at work. I have been told that the the NT Operating system will not allow me to "talk" directly to the video hardware. Have you ever heard of this?

Thanks!!!

Oh the joy of being a programmer. Just to let you know I have figured out my problems. I am assuming that the driver NT uses to emulate a dos window has the video set to a default video. Because, what I failed to do was save the current video and restore it back after my program ended. So, on my Windows/98 when did not restore the mode I just lost the cursor. But, on my work Windows/NT system when I didn't restore the video mode the screen was really messed up. As it turns out using int 10h on vga or svga works just fine.


Thanks again,

Rod
