you need to know which sector on the disk the old FreeBSD partition started on.. and use fdisk -u (not -i) to adjust your start block first, to 0 then 1 then 64 each time, reboot, and then do a disklabel sd1 to see if it finds anything.. If it aint one of those, you'll need to search for the disklabel.. (it has magic numbers in it so it can be found..) and fdisk -u used to adjust.. > > > i installed 2.1.0-RELEASE using the boot floppy to install to sd1 > (imprimis drive). 1.1.5.1 was on sd0 (seagate drive). after the install, > i tried to boot to sd0 (the 1.1.5.1 disk).
