hi i'm wondering what video mode do i need to change to make graphics like win xp and what other requirements before I start displaying colors (ie. any thing like protected mode or real mode stuff)? I'm just starting off on the gui in my os.

You can use any video mode, but better use 32bit color mode. There are no requirements. You can do it in real mode and in pmode(in pmode it might be faster).

That's a "tutorial" I wrote a few years back. It includes code for developing VGA/SVGA (Vesa 1.0 - 2.0) in pmode (using DGJPP). The general theory, and most of the code is portable to any OS/project.
