Well i have some graphics routes that i have written but i can't figure out 
how to show a double buffer. I am useing VESA 2.0 Linear addressing useing FAR 
PTR's. I thought all i had to do was setup another array for the double 
buffer. Then gets it's selectors value useing _my_ds() then uses movedata to 
copy this to either the screen or the video buffer i allready have setup.

int video_buffer2(width*height);

movedata(_my_ds(),(int)&video_buffer2,ADDR,video_buffer,(width*height));

also:i get an error when i run it ;it says undefined _my_ds() but i'm include 
the right headers and stuff.

I'm getting really confussed because ever time i compile it's cool but when i 
run it, it restarts my computer ever time i don't know what to do.

Please Any help will be whould really make my day.
