Hi, 

For easy installation, what I have done is below.

  Machine-A: i386 PC(NetBSD/i386) with HDD-A.
  Machine-B: DEC5000/25(Ultrix) with HDD-B.
  HDD-C: Target.

1. Connect HDD-C to Machine-A and boot NetBSD/i386 on HDD-A.
2. Write disklabel by NetBSD/i386's disklabel.
3. Mount HDD-C and extract all NetBSD/pmax binary.
   <At this point HDD-C is pure NetBSD/i386 disk>
4. Do "MAKEDEV all" on HDD-C and check /etc.
5. Connect HDD-C to Machine-B and boot Ultrix on HDD-B.
6. Write bootblock by NetBSD/pmax's disklabel for Ultrix.
   <At this point, HDD-C is NetBSD/pmax bootable but unable
    to mount on NetBSD/i386.>
7. Boot NetBSD/pmax on HDD-C and enjoy!

Takuya.
