	Wow!  Installing NetBSD is getting interesting.  First of all, I 
have access to no docs on Sun3 machines (if I wanted Sparc, DECs of any 
shade, SGIs, or even HPs I could get them quite easily).  Also, my 
"low-level" background has been mostly Ultrix.  So, I pretty much have to 
rely on this list.  I hope my questions do not sound that stupid. =)

While shopping for shruberries, Tom Samplonius pondered:

	How would I go about booting the machine diskless and then using tftp 
to get the kernel?  From the 1.1 docs, I understood that you would first 
have to have access to either a tape drive or NFS server.

About using a NFS server, could I use a DEC box (Alpha or ideally (as far 
as I am concerned) Ultrix box) as the server for the 3/50?  If so, how 
would I go about that (I never set up a NFS server)?

	Thanks for the info!

	Given the 1GB drive I will eventually put on the machine 
(whenever it arrives, that is), what would be the recommended partition 
sizes to run NetBSD in the 3/50?  I myself though on having one partition 
big enough for the basic root stuff (32-50MB is big enough?), another 
30-40MB for swap since I do not have that much RAM, and the rest for /usr.
