The startup probe reports 119150/16/63. When I try to configure the drive, I get a message saying 119150/16/63 is incorrect, and that I need to set it to the BIOS numbers. If I set it to the BIOS numbers, it still complains that it is incorrect. There is a message in there warning me not to set the drive to its physical geometry, though the BIOS 29437/16/255 seems a likely physical geometry. So the partition editor picks another default, which is 7476/255/63. Which seems to work, but now I have three different numbers. The boot still shows 119150/16/63, the BIOS still shows 29437/16/255, and the disklabel shows 7476/255/63. Question: Why the warning about not using the PHYSICAL GEOMETRY, especially since the BIOS (on a Tyan K7 MB) reports a proper physical geometry? Why is the boot message still reporting 119150/16/63, when that isn't set anywhere??? stu fbsdstable@cobble.capnet.state.tx.us To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
