Hi Philip,


    I read your guide in conjunctoion with the one from netbsd.org and 
the most glaringly obvious difference is in the part where it sets up 
the 1st disk to be bootable.


=================================================

netbsd.org

# */usr/sbin/installboot -v /dev/rwd0a /usr/mdec/bootblk*
File system:         /dev/rwd0a
File system type:    raw (blocksize 8192, needswap 0)
Primary bootstrap:   /usr/mdec/bootblk
Bootstrap start sector: 1
Bootstrap byte count:   4915
Writing bootstrap



Philip's

*# **/usr/sbin/**installboot /dev/rwd0c
/usr/mdec/bootblk

# mount /dev/wd0a /mnt

#** cp /usr/mdec/ofwboot /mnt

# cp /netbsd /mnt
*

=================================================


I have 2 questions....

why does one use rwd0c and the other rwd0a ?

and is it necessary (or even possible with 2.0) to do the 'mount' part 
to copy the kernel and boot 2nd stage boot loader to the other disk ?
