It was an accident, because of my boot configuration I have a lot of
kernel-files in /boot that does not get deleted when kernels updates or
are removed.

BTW. I boot from sda, and have installed f9's bootloader on sdb, how do
I simply hand over the boot-process to the grub on mbr on sdb?

I have tried with:

root (hd1,0)
chainloader +1

in grub.conf there is a line in the comments like this:

#boot=/dev/sda

Is this just a comment, or is the line used?
