I am sorry, I should explain the situation a more
clearly. I have already run the FreeBSD 5.4
installation program, which seems to have completed
successfully, to install FreeBSD on the hard drive.
However, after I reboot the system after the
installation program completes, I cannot boot FreeBSD
from the F1 FreeBSD prompt. It just beeps when i press
F1. I then booted into the fixit floppy, and it does
appear that the FreeBSD system is there on the hard
drive. Why I cannot boot the system I dont know. I
thought it might be a boot record problem, so I
wondered if I could use a floppy disk with a boot
loader on it, which could then be used to start the
system on the hard disk.

I thought the install program would replace the boot
records, in fdisk  I have marked the partition active,
and it prompted me to install the boot loader. I have
several times gone into fdisk to try to get the boot
records replaced.

I tried using one of the boot floppies used to start
the freebsd install, (kern1.flp), which if I boot off
of that I get what appears to be a boot2 (boot:)
prompt where I can type ad(0,a)/boot/kernel/kernel, to
boot the FreeBSD system i have on the hard disk,
however after doing so a lot of numbers and gibberish
appear on the screen with the message "BTX Halted". 

I do have a fixit floppy so I can try to get in there
and do some more things to fix this.
