It will work when you install grub after booting from floppy disk or CD.
Wow, that's a bit messed up - I need to boot off a different disk before I can write to the MBR? Someone mentioned a GEOM quirk, is that what's stopping
me doing it from within freebsd?
I wonder why boot0cfg doesn't have the same problem?
You may create a bootable grub floppy with $ cd /boot/grub $ dd if=stage1 of=/dev/fd0 bs=512 count=1 $ dd if=stage2 of=/dev/fd0 bs=512 seek=1
Thanks, but if it's a freebsd thing I'll just install the MBR from one of the other OSes - do you know if I need our patched grub for the mbr to grok ufs2, or will a leenux one work?
Setting the sysctl: kern.geom.debugflags=16
will allow you to write the bootsectors right from grub-install while having a live root filesystem mounted.
