Rogelio,

The easiest way to change the colors on the screens is to use Xmode. If all you 
want to change is /term and don't care about the boot screen, after booting enter
xmode /term
You will see the values for fgc, bgc, and bdc. You will want to change those. 
For a 24 line screen, you will also want to check pag.

The values I have for a white screen with black letters 80x24 are:
pag=$18
fgc=2
bgc=0
bdc=0

xmode /term pag=18 fgc=2 bgc=0 bdc=0
Now you want to make those changes permanent so ex.
cobbler /D0

If you have a hard drive, cobbler may not work for you so you can edit OS9Boot 
with ded to make changes to OS9Boot.
