FAT and RDB

[KIYOHARA Takashi <kiyohara%kk.iij4u.or.jp@localhost>]

Hi! all,


Please support to load from FAT on RDB partition.
I create FAT on RDB partition by MorphOS 2.5.  And ofwboot succeed to
load the netbsd from there.

  Boot: /pci@80000000/ide@C,1/disk@0,0:e/netbsd


My rwd0d:
  # dd if=/dev/rwd0d | hexdump -C | less

By the way, how create DOST_NBR partition?
Do you forcibly make it with the binary editor?  For instance, use bvi
and the DOST_MSD partition.  ;-)
