Yes.

That has been my goal. Unfortunately, my Video Card does not support
linear address, ( it failed with the testlinear.exe program ),
and I end up using the scr_svga.c driver of MicroWindows.

Anyway, the goal is to use the framebuffer interface and use this
library to set the video cards in graphics mode. Hopefully, someone
out there has a video card with "linear" support to test this out.
