AFAIR, there is yet another issue with boot0cfg - it doesn't set active attribute when `-s` option is used. But i'm not sure that it should do this. -- WBR, Andrey V.

boot0cfg -B can't work
I want to rewrite boot0 into mbr but failed, infos follows: # boot0cfg -B ad2 boot0cfg: write_mbr: /dev/ad2: Operation not permitted # ls /dev/ad* /dev/ad2 /dev/ad2s2 /dev/ad2s2b /dev/ad2s2e /dev/ad2s2g /dev/ad2s1 /dev/ad2s2a /dev/ad2s2d /dev/ad2s2f /dev/ad2s3 uname -a FreeBSD bsd.hasee.cpu 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #0: Sun Dec 5 19:14:33 CST 2010 r...@bsd.hasee.cpu:/usr/obj/usr/src/sys/HASEE i386 -- Regards, Yue Wu Key Laboratory of Modern Chinese Medicines Department of Traditional Chinese Medicine China Pharmaceutical University No.24, Tongjia Xiang Street, Nanjing 210009, China ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Instructions for temporarily disabling these protection mechanisms can be found in the geom(4) manpage. Specifically, do a sysctl kern.geom.debugflags=0x10 to allow writing to the MBR, and restore it to 0 afterwards.
