can someone point me to the right bit of code that handles djgcc's graphics
library? specifically, how the translation from a linear address space
is converted to a physical address space, in order to do bank switching.
and also, how the driver files are loaded and interfaced to djgcc programs.

I know the video memory is mapped around with the 386 paging instructions,
but a tip on which file handles all of that would be appreciated.

as far as loading the drivers, how is it handled and how does the C programs,
make calls (there must be some kind of interface)

I've downloaded all the graphics stuff, but it's a lot to go through.

thanks
