You can build a new boot disk using the scripts that come with the distribution. 
Change the mb.floppy file (if that is what you are booting) so that rel_80 is 
changed to rel_40. That will get the first boot screen changed.
Also change the standard.bl so that term_w40.dt instead of term_w80.dt is used. 
That will change the size of the initial window.
With this approach, the colors will not have changed and you will need to do 
that using xmode. Xmode could also be used to change the window size but that 
would not change the boot screen.

xmode /term

will display the screen parameters. You will see fgc (foreground color), bgc 
(background), and bdc (border). Changing these values will select the palettes. 
Try  xmode /term fgc=2 bgc=0 bdc=7
Add to your startup file the line
montype -c
as your TV is a composite monitor. By default, the current NitrOS-9 is set to 
RGB monitors.

Once you have used xmode, you will need to make the changes permanent with
cobbler /dd

If you don't care about the width of the boot screen and don't want to create a 
new boot disk, xmode can also change the width of /term.
xmode /term col=28
If you find there are too many rows for your TV to easily display, use xmode 
with pag and row to decrease the number of displayed rows and the location of 
the screen pause.
