	Oh great.  I've already made the 8mm tapes.  It seems it is time 
for me to find a victim I can borrow a QIC 24/150 tape drive from...

	About netbooting, wouldn't that require, as far as I could gather 
from the guide, that I will need to start the 3/50 from a tape anyway.  
If that is true, shouldn't I simply use the tape to install netbsd in the 
first place?  I am confused.

	That I understand.  However, if I am not mistaken the a partition 
defaults to 32MB, the b also is 32MB, and so on.  I know that I can 
change that *once* I have a live machine to play with, but how to go 
about doing that *before* having a fully operation netbsd box?

	I see.  If I were to run diagnostics, can't I simply slap a null 
modem and a PC/Mac running some comm rpogram in its serial port and set 
it to 9600 8/N/1?
