by the way I use: C as my programming language
Protected or real mode?
protected mode
VBE could be an option. VBE 2.0 and up should be able to work nicely with protected mode, too (no need to do pm->rm->pm on every VBE call), though you need to do some initialization in real mode. For more information, search the net for something like protected mode vbe.

Here''s the VBE3.0 standard (1998):

thanks, it helped me a lot
I have a small VESA 2.0 example on my homepage that''s written to work in protected mode (however under DOS using the Watcom compiler).
If you want you can look it up:
