I've written a function (in djgpp) that writes a pixel on the screen in
SVGA. It works fine.

Now i want to write the same function but in assembley, but there is a
problem.

In djgpp i used _farpokeb to write to the video memory, because protected
mode don't let me do a direct write.

How can it be done in assembley?

Another question.
When i wan't to call a dos interrupt in djgpp i use dpmi_int, no problem.
But if i wnat to call the same interrupt but in assembley, can use the
function INT?
I tried, and it seemed to work fine, but i wnat to be shure that tere are
no problems.

Thanks, Jorge Lima from Dark Angel Soft, Portugal
