First of all thanks to the off-list responders. I already considered the chainloader option but as I installed no bootloader this probably would not work. I examined the Grub source code to find out where it looks for BSD partitions. I found there is a sector containing the BSD magic label and appropriate partitioning info. It's sector 1, the second one on the disk == the first in slice /dev/hdb1 or (hd1,0), respectively. Arrgh! Sectors 6323185 and 6323186 are still untouched. I tried to use the 'b' command in 'disklabel -E ..' but nothing went better. I dd'ed sector 1 to 6323186 and voila - there they are. Could this be the correct way that I first have to damage another partition and then manually have to move a sector? When booting this system I run into the next problem: panic: /boot too old: upgrade! Therefore I would like to try to install a bootloader and chainload it. But with a 'disklabel' that overwrites existing partitions? Do I have to get used to struggle with such fundamental problems when I proceed with OpenBSD?
