>>> Question #2:
>>> Is there any way to set the state of the NumLock key.  I already know

Here's what I use to turn off num-lock on a machine that doesn't give
me the choice of initial num-lock state in the CMOS setup. You can
enter this using DEBUG and save it as a num-off.com file to be run in
your autoexec.bat. By the way, it takes care of the indicator light,
too:

  1E      push ds
  31C0    xor ax,ax
  8ED8    mov ds,ax
  BE1704  mov si,0417
  8A04    mov al,[si]
  24DF    mov al,0df    ; change this mask for caps & scroll lock as well
  8804    mov [si],al
  1F      pop ds
  CD20    int 20

If you turn this into a source file to be assembled, note that the
numbers 0417, 0DF and 20 are in hex, and this starts with org 100h.
