  I'm currently in the process of writing an interrupt handler for both the
keyboard and the mouse.  I have the protected mode version of the keyboard
handler finished, but what I'd like to know is whether I should also have a
real mode version of the driver.

  Somewhere I read that if you are running under windows, so that it uses
Windows dpmi server, that you only need a protected mode driver.  How
about under DOS?  Would it be more effecient to have both a real and
protected mode driver for both the keyboard handler and the mouse handler?

Thanks in advance!
