dd 1m zero on the drive and rerun the 8.0Beta4 DVD. Created two slices S1 a= nd S2, and did auto labling (unix partiton) on S1, hit W, the problem persists. Boot system with freeBSD 6.4, and 6.4 sees two slices (MBR partitions) S1 a= nd S2,=20 but no any Unix partition (ad0s1a, ad0s1b etc) on S1. Boot back to 8.0-Beta4, it still sees not Slice created.=20 At this point, it is obviously that 8.0 looks in a wrong MBR location -- 8.0 created slices can be seen by 6.4 but not 8.0 itself. --- On Mon, 9/14/09, Thierry Thomas <thierry@FreeBSD.org> wrote: > From: Thierry Thomas <thierry@FreeBSD.org> > Subject: Re: 8.0-Beta installation problem -- Unable to find /dev/ad0s1b > To: "Jin Guojun" <jguojun@sbcglobal.net> > Cc: bugs@freebsd.org, freebsd-stable@freebsd.org, current@freebsd.org > Date: Monday, September 14, 2009, 10:06 PM > Le Lun 14 sep 09 =E0 23:08:53 +0200, > Jin Guojun <jguojun@sbcglobal.net> > =E9crivait : > > I do not enve know how to make "dangerously dedicated" > disk, and the > > 8.0 may do this sliently. >=20 > No, I don't think so!
