Here is how the Linux boot loader works (I did not write so I am giving you
only a functional description, you can check out the details at
under Howto section under LILO.

Linux uses a boot loader called LILO. LILO may use the MBR. It uses a file
callled /etc/lilo.conf. In this file you specify which image to boot from
where and it also uses a map of the disk drives. You run lilo, it installs
the boot loader then you are ready to go. In FREEBSD , as far as I know
there is no easy way to install a boot loader from FreeBSD itself, or at 
least I could not find it. Moreover the Booteasy program is not exactly
configurable and it can not boot from a SCSI disk when IDE is present.
Now I found this program called os-bs on the Walnut Creek CDROM and that
was able to boot from a SCSI disk provided that the SCSI disk is
visble from DOS at the initial installation. The only bummer with this 
set up was the fact that the bootstrap code kept on referring to the scsi 
drive as sd(2,a) which was clearly wrong. It should have been hd(2,a) the 
third hard drive or sd(0,a). IN either case to go around this I hard wired
the scsi drive to be sd2 on the kernel configuration file, re compiled
the kernel and there we go.

Another thing that is missing from the FreeBSd project is the lack of 
documentation. I would be tempted to start a set of HOWTO's just like
the Linux project. Maybe that will help the users. The FAQ and the Handbook
are kind of weak for specific information although they do provide a great

Well this it.
