hi out there,

I am trying to write a program that reads the screen buffer and changes
the contants. It works with monochrome display machines as I use the
adress 0xB000; but when it comes to VGA or any other monitor, it gives me
some trouble. I am using the address 0xB800, I think thats the right one
as I have checked it in many ways.
BTW, I am using C, if that matters.

Can anyone give me a hint?


thanks alot
