Note that %eax is zero. :Do you have dangerously dedicated mode on by chance? Some :SCSI BIOS's _will_ crash with this if you use dangerously :dedicated mode. : :-- : :John Baldwin -- http://www.FreeBSD.org/~jhb/ Yup. The real question is: Ok, so if I can't use dangerously dedicated mode, then how do I create a disklabel on a normal partition? Everything I try using fdisk and disklabel fails. fdisk will create a normal freebsd-dedicated dos partition, but disklabel refuses to label it. Beyond that, our 'dangerously dedicated' disk label should at least contain reasonable values -- be correct enough to pass BIOS muster. I don't know enough about the partition format to know where the BIOS calculation is failing. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
