Two drives ad4 and ad6 are arranged with gmirror as the operating system (7.1 Stable). The FreeBSD boot manager is installed for this mirror and I would like to remove it and use the standard FreeBSD MBR ...without messing anything up. Can I perform the fdisk -B /dev/ad4 followed by fdisk -B /dev/ad6 from a livefs disk? Maybe fdisk -B /dev/mirror/gm0? I have backups but everything is running very nice right now. I don't reboot very often but I _would_ like to get rid of the boot manager Thank you Robert
