In addition, > boot0 is working in "packet mode". packet mode doesn't use the starting C/H/S, it uses the starting offset. Also, as long as the you have the sectors right, ad0s1's starting C/H/S is ok. However, if you have the cylinders and/or heads wrong, then the C/H/S for ad0s3 is bogus. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
