I didn't, sysinst (1.3.2) did:


8 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:   264120       63      4.2BSD     1024  8192    16
  b:  2100117   264183        swap                     
  c: 17759877       63      unused        0     0      
  d: 17759940        0      unused        0     0      
  e:  2100180  2364300      4.2BSD     1024  8192    16
  f: 13295460  4464480      4.2BSD     1024  8192    16


(cylinder count snipped to avoid lines wrapping)

I still can't see the difference between using this disk as I have
above, or using partition c for one big filesystem. Where does it say
not to use partition c? References, please.

Note that when discussing this issue I'm always talking about a NetBSD
only system. I couldn't care less about coexistence with Messy-DOG or
Winsnooze or whatever. People who do are not using NetBSD, they are
toying with it.

As I see it our major problem is braindead BIOS' who are too smart for
their own good (trying to read a disk's "DOS" partition table to
determine the geometry in use etc.) Would using partition c from the
disklabel above break on some BIOS'?

(What _is_ the correct plural of "BIOS" anyway? ;-)
