# I do have access to the BIOS. But my application runs in protected
# mode. I am starting to gather up some documentation on VGA and will
# try to see if I can access the video memory directly. I know that I
# can access the I/O ports in protected mode.
#
# A silver lining to the whole thing is that the keyboard problem might
# make a good exercise to introduce my students to Ada interrupt
# handling.
If it can help:

It is GNAT & DOS-centered, but some pieces access the BIOS;
there are example of interrupt programming from protected mode.
