I wanna enable high resolution graphics mode, without protected mode (I really dislike pmode, don't know why). In OSDev Wiki I found how I can set up unreal mode, but how can I set up VESA and use it in unreal mode?

I'm using nasm to compile my code, and I have already written a boot loader that can load 64k from floppy and execute it from 100h like DOS. I want some completed codes rather than snippets.

Forgive me for my BAD English, anyway.

Maybe because you haven't spent any time trying to understand it?

Just as you do it in real mode. Unreal mode is only popular because it lets you use the BIOS interrupts.
