New Convert/Simple Question

Hello, I am new to NetBSD in general and likewise to the NeXT port of it,
however I am in need of installing it on 10 NeXT slabs.  I looked through
documentation and the archive of this list but could not find a definate
answer to my one question:

Once NetBSD is installed on a slab, can I boot from the internal drive and
use the internal drive to store data?  Which kernel patch leverl do I need
for this?

Thank you very much, I apologize if this information is out there, I could
not find a clear answer to this.  Thank you for your time!
