Incorrect.  I personally only use Int 10h for one thing and one thing
only, and that's changing the video mode.  Once the mode is set
(usually mode 13h or a tweak thereof), I never touch the interrupt
again.  Int 10h is incredibly inefficient - you can't get any decent
hardware speed from it whatsoever.  My advice - Use it to set modes,
and do the rest manually through the VGA registers.

Of course, using VGA registers is lot faster, (pixel plotting like things)
But it's often hard to program through VGA registers. In this case, 
changing default fonts, there is no need for speed, and mostly need for
efficiency. I would not recommend using VGA registers to reset the font.
No thanks. Int 10h sounds much easyer in this case.

But VGA registers have their uses of course. I have no doubt.:)
