Hi, I gather not (yet?) Can save the MBR with (eg) 'boot0cfg -f ~/mymbr adaX' for safety, dd it back if need be, and/or use fdisk(8) -p, -t and -f flags to save, test and restore just the slice table. At least they're precautions I'm taking, really not wanting to clobber win2k (for BIOS updates :), 8.2-RELEASE or a shared UFS partition when next trying to install 9.0-RC2 to slice 2, currently 7.4-RELEASE .. % boot0cfg -v ad0 # flag start chs type end chs offset size 1 0x00 0: 1: 1 0x0b 1023: 5:63 63 8385867 2 0x00 1023:255:63 0xa5 1023: 13:63 8385930 125821080 3 0x00 1023:255:63 0xa5 1023: 15:63 134207010 33543342 4 0x80 1023:255:63 0xa5 1023: 14:63 167750730 66685815 version=2.0 drive=0x80 mask=0xf ticks=182 bell=# (0x23) options=packet,update,nosetdrv volume serial ID a8a8-a8a8 default_selection=F4 (Slice 4) % fdisk -p ad0 # /dev/ad0 g c232581 h16 s63 p 1 0x0b 63 8385867 p 2 0xa5 8385930 125821080 p 3 0xa5 134207010 33543342 p 4 0xa5 167750730 66685815 a 4 cheers, Ian _______________________________________________ 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"
