Data disks were normally the c partition (entire disk). I also
remember much fun with the bc command (basic calculator) to work out
my partition sizes and layout and disklabel -er to edit, something
like 32mb for a, RAM size * 1.5 for b and g or h being the rest of the
disk. After that the install was automatic. Also remember I've not
done this since 1996 or thereabouts :)

My NetBSD knowledge is limited to a single install on a VAX3100 a
looooong time ago.
