adding a linux boot option

[Jonathan Horne]

i have a system with 2 disks (ad0 and ad1), with ad1 having a recent suse 
linux install, and ad0 is a standard freebsd install.  i must have made a 
mistake when i installed the suse, as i overwrote my freebsd bootloader and 
only had option to boot suse.

so i then reinstalled freebsd, and i again must have made another mistake, as 
the freebsd loader only shows F1 for Freebsd, and nothing else (well, F5 for 
drive 1, but that does nothing usable right now).

is there an easy way i can add an option to boot the OS located at /dev/ad1s2?

cheers,
jonathan
