Hi,

After playing around with Xen I would like to get my machine back to
how it was before. That involves 'deleting' grub boot manager.

In order to do that I've tried to do:

cp /usr/mdec/boot /boot
installboot -v -o timeout=5 /dev/rwd0a /usr/mdec/bootxx_ffsv1

as listed in installboot(8). 

But that didn't help, grub still comes up.

How do I restore my system so it boots directly into NetBSD without
grub ?

Thank you
