That's so cool.

I still need more information about the actual driver and how to make it work in Win XP. I can probably write an INF file but i need to know the actual driver files first.

Can you help me?

vbe driver files:
  • miniport driver: system32\drivers\vbemp.sys
    driver dll: system32\framebuf.dll
I hope I didn't forget something :roll:
