You need to invoke an interrupt for retrieving a pointer to the font's location:

You can also re-program it to use other fonts, this way you can use the unused fonts, to make a logo for your OS, see below.
I have a demo some where.

I once built my own 4x4 font. (For working in basic VGA mode... or was it CGA?)

Anyway, it was bulky, blocky and sometimes hard to read... but it worked.

Its in video memory as well - With a small bit of VGA trickery you can get it out.
