Use the details in the handbook to make a kern.flp floppy.  Boot the floppy,
when it prompts for the MFS root floppy, just leave the floppy in, press
Enter and ignore the error.  When it starts to countdown, hit space.  You
will now have a loader prompt.  Type lsdev which should display the devices
on the system.  One of the disks will have your BSD slice in it, and the root
partition will have a name like disk1s2a (the root partition ends in 'a').
Type 'set currdev=disk1s2a' or whatever the proper partition name is.  Then
type 'unload' to unload the kernel from the floppy, type 'load /kernel' to
load the kernel from the hard drive and then type 'boot' to boot.

Once you are booted into FreeBSD, you can use boot0cfg to install the boot
manager onto your hard drive.  Read the manpage for more details.  HTH.
