boot floppy

[Tim Newsham <newsham@aloha.net>]

Hi,

   I would like to create a floppy that has the BSD loader
on it that will boot hd(2,a)/bsd by default.  Right now
I use a floppy to boot my system and have to manually
type hd(2,a)/bsd each time.  This is normally fine, but
now I would like to start booting headless.  I can do
this by watching the floppy lights, but its quite irritating.

I have tried in the past to modify the boot program.  Every
modification I make ended up creating a boot floppy that
crashed even before my code ran (locked up before even
reaching the prompt, I put my code after the prompt),
or malfunctioned in some other way.  Has anyone else done
what I am trying to do?  What are the constraints of
the boot loader program?

Oh, this is for x86, btw.
