8.0-RELEASE / gpart / GPT / marking a partition as active
It seems that quite a few BIOSes have serious issues booting off disks using GPT partitioning when no partition present is marked as active.

After using gpart to create the GPT (and thus the PMBR and its bootcode), why not simply use fdisk -a -1 DISKNAME to set the PMBR partition active? According to the fdisk output, the partition flag did change from 0 to 80. Can the fdisk: Class not found error showing up at the very end of the procedure of doing fdisk -a -1 DISKNAME be safely ignored? - Dan Naumov ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
