Hello World,

I am trying to adapt the VDD for a 1024x768x4 display. I'm having a tough
time with one little problem, which I'm sure requires just one small 
change in the code : when switching from Windows to a full screen DOS
window and from there running a non Windows application in 1024x768 mode,
this application cannot write into the bottom third of the
screen (mapped to segment B8000). However, when I run this application from
outside Windows, everything works fine.

Does anybody know what can cause this type of behaviour ?

Thanks for your help,

Etienne Cornu
