The partition editor insists that 119150/16/63 is not a proper geometry for the drive, so there isn't much point to setting it that way in the BIOS, but I can't, anyway. The BIOS (both on a 1rst MB and a Tyan K7) cannot be set to a six-digit number for the cylinders. So, why does the partition editor think the 119150/16/63 numbers would be a bad selection??? It is what it is getting when it asks the drive, apparently. Why should I _not_ use the numbers in the probe, and why not use the BIOS reported numbers? stu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
