Ok, tried it, but disklabel always want to use wd0a as root-partition. That's what disklabel(8) says: "By convention, the `a' partition of the boot disk is the root partition, and the `b' partition of the boot disk is the swap partition, but all other letters can be used in any order for any other partitions as desired." How did you do the install? Another problem is the bootloader. AFAIK you can only define the hd and fdisk-partition, not the disklabel-partition to boot from. Could you please give me some more informations about your setup? Regards Hagen Volpers
