The bootcode is BIOS based, so it *has to* be able to load /netbsd
from inside BIOS addressable space. Therefore you need to have the
'/' partition entirely within the BIOS limit. (e.g. 1024 cylinders)
It is not sufficient to have '/' start within the first 1024 cyls, as
the kernel will not necessarily be at < 1024 cyls. It would require
reverting to hardware specific bootcode to get around this. But..
who needs anything other than NetBSD on the disk anyway.. :)
