This is a erroneous message. The actual problem is: 484 boot0cfg NAMI "/dev/twed0" 484 boot0cfg RET open -1 errno 1 Operation not permitted This is a known problem with certain MBR layouts. To work around this problem, set: sysctl kern.geom.debugflags=16 then try your boot0cfg. There's a protection mechanism that sometimes gets confused by certain partition table layouts. Flag 16 disables that protection. I don't recommend running this unless you are explicitly trying to updating something in a partition table-like area; its very easy to destroy your system with the flag set! -- Doug White | FreeBSD: The Power to Serve [EMAIL PROTECTED] | www.FreeBSD.org _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
