Using a linear frame buffer is always going to be the fastest, but as you stated being in a banked mode makes things a little more difficult. With VESA 2.0 you get access to a Protected Mode structure which gives you access to a direct bank switching function so that you no longer have to switch to realmode every flip. The code for that is in my VESA tutorial on my site. http://www.fm-net.com/inversereality later! Justin Deltener
