I wrote a chapter about graphics in protected mode, using DJGPP specifically.

You can take a look at it here:

You should note that much of this is OS specific (using the Vesa BIOS, for example).  All my routines are fast (I've profiled many different versions), and if you wish, you can take a look at the source code for Petal (my graphics library) for some hand optimized assembly routines.

BTW: in short, all you need to do is _copy_ is (ie, memcpy); assuming you've set up the video mode correctly.

Cheers,
Jeff
