If you use the available extra terminal functions like
"<ESC>L" = insert line
"<ESC>M" = remove line
together with disable/enable cursor: "<ESC>x5" / "<ESC>y5"
you can still get a nice textscroll through BIOS!
Of course, if you use this, you rely on a fast implementation of these
commands. That is why the uzix-kernel or the C-libraries (which can
also be used by a assembly-program!), should be optimized, maybe with
handmade assembly for hardware stuff.
