(They are also obsolete as gpart can do MBR partitioning, too.) So in your case, the following approach should work: # gpart create -s gpt ada1 # gpart add -t freebsd-boot -l gpboot -b 40 -s 512K ada1 # gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada1 After installing the boot code, add data partions as desired: # gpart add -t freebsd-ufs -l gprootfs -b 1M -s ada1 Refer to: http://www.wonkity.com/~wblock/docs/html/disksetup.html#_the_new_standard_g= pt --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
