The disk needs to have at least one partition that's marked
as active, if I remember correctly. This is the "old way"
of initializing it:
# fdisk -BI /dev/ada1
# bsdlabel -B -w ada0s1
Add "-b /boot/boot0" for the fdisk command if you need to
specify the boot code (normal boot or boot manager).
If you want to use the whole disk as a "dedicated partition",
you can do this:
# bsdlabel -w ada1
# bsdlabel -e ada1
set type "4.2BSD" for 'a' partition
make 'a' same size as 'c'
# newfs -m 0 -i 16384 -b 16384 -f 2048 -U -t enable -n disable -L ssdroot /dev/ada1a
# bsdlabel -B ada1
Adjust -i, -b and -f according to the expected usage.
But that's not a very kind way to deal with disks. :-)
You should use gpart today. There is good documentation
in "man gpart", as well as those resources:
Avoid MBR partitioning if possible - it's considered obsolete,
outdated, old-fashioned, stupid and lame. ;-)
