In my previous message 
http://mail-index.netbsd.org/netbsd-users/2005/04/06/0002.html

there is a typo.
in step 5 you should, of course, install bootblocks to wd1
rather than wd0:
-------------------------|
                         v
   # installboot /dev/rwd1a /usr/mdec/bootxx_ffsv1

Also, copying /usr/mdec/boot to the correct location is only possible
if the target fs is mounted, i.e.
   # fsck wd1a
   # mount /dev/wd1a /mnt2
   # cp /usr/mdec/boot /mnt2/boot


In step 6 I should have been more precise. When checking fstab
and dev/ the reference should have been to a mounted /dev/wd1a.

So assuming you have booted from the install cd and mounted wd1a
to /mnt2, then the correct commands would be:

   # cd /mnt2/dev/
   # ./MAKEDEV all

and fstab would have been in /mnt2/etc/.


In order to (re)initialize wd1 mbr with boot code without bootselector, 
which is adequate if there is only one OS on wd1, you can
   # fdisk -i -c /usr/mdec/mbr wd1
