# BUNDI - Build the Ultimate NitrOS-9 Disk Image
#
# This script builds the ULTIMATE NitrOS-9 disk image,
# complete with HDB-DOS drives!
#
# The resulting image has a NitrOS-9 partition and an HDB-DOS partition.
# The first drive of the HDB-DOS partition is the HDB-DOS distribution
# diskette.  The last drive is the NitrOS-9 boot disk.
#
# Size of image is 90,624 256-byte sectors, which fits in
# $00B100 OS-9 Offset in HDB-DOS
