 IIRC currently ISO CD for NetBSD/sun3 isn't bootable.
 (it should be trivial if we can use the same method with sparc)

 If SunOS miniroot mounts /dev/sd0b as R/W and uses it for swap,
 dd'ing into it is problematic. Instead, you could try:
 
 > 1) b sd(0,30,3) with the original sunos 4.1.1 bootable cd
 > 2) used the sunos procedure to copy the sunos miniroot to /dev/rsd0b
  3) b sd(,,1) -s into the sunos miniroot, then used it to mount the netbsd  
     cdrom, and copy the netbsd miniroot to /dev/rsd0a. (not sd0b)
  4) halt
  5) b sd(,,0) -s into the netbsd miniroot on sd0a
  6) mount the netbsd cdrom, and copy the netbsd miniroot to /dev/rsd0b.
  7) halt
  8) b sd(,,1) -s into the netbsd miniroot on sd0b and proceed installation
 (not tested at all)
