Hello,

I have a program which uses tweaked 320x400x256 mode. According to some
docs I have two pages in this mode (256k / (320*400) = 2, right?).
Well... I assume that setting a pixel at (x,y) on page 0 is about
modifying the corresponding vram offset located in the first 128000 bytes.
Adding 128000 to that is the same thing for page 1, right?

Now what I'd like know is how to control which page is being displayed
(by default this is page 0, I guess)?
