I ran into a limitation I couldn't work around. I needed to scroll forward or 
backward by n characters. But the bios has no easy way to do this. It can be 
done through bios, but it would require many calls to set the cursor, read 
the character and attribute at the cursor, etc. Direct access is the easiest 
and quickest way to do it.

But it does seem advantagous to provide a bios-only solution, so I'll 
probably work on that after the color stuff is added and after some more 
testing is done on what's already been done.

And if you or someone else could clue me in on what modes require a bios-only 
solution, that would be a help.
