It's covered in the INSTALL document.

You say above that you put it at cylinder 410, but the MBR says that it is
put at cylinder 408? These offsets _must_ match up! (and I am pretty sure
that this is also mentioned in the install document).

165 (0xA5) ... also mentioned in the install document. (Gee, I sound like a
broken record, don't I? :-) ).

If you get this message, then you've partitioned your disk wrong. When you
install NetBSD, you _must_ give the same offset to the install program that
you setup in the MS-DOS partition with pfdisk. If this is done correctly,
you shouldn't see the above message.
