You need to specify a slice. I generally don't depend on the 'auto' magic -- it breaks for IDE disks, and I'm not sure it works for slices either. > OK, may I ask what the ".. magic .." part is?? Take a look at src/release/picobsd/install/floppy.tree/etc/prepdisk in the source tree. This is an awk script that generates a root partition and 255MB of swap on the target disk by doing the higher math on the number of sectors on the disk. You may have to change the disk type in the script but otherwise it's the same for IDE and SCSI. I'm looking at the script and notice that it doesn't select slice 1... somehow disklabel DTRT. It works here :-) Doug White | FreeBSD: The Power to Serve dwhite@resnet.uoregon.edu | www.FreeBSD.org PS: http://www.freebsd.org/cgi/cvsweb.cgi is really handy for browsing the source tree.
