# This is a convenience Makefile to add SystemDisk, BootX and
# a couple of current linux kernels to a bootable Mac OS CD.
# It tries to do the right thing (tm) ;-)

#
# Dependencies: hfsutils, cdr-tools
#
# Usage: The only thing you should need to adjust is the
#        BOOTABLE_MAC_CD variable or *URL if the URLs listed
#        deliver a "404 not found".  If you have a rewritable
#        cd handy, adjust CDBURNER and try make cdrw.
#
# Motivation: Even in the lucky case you get bootloaders for
#             a Beige G3 working (miboot, quik, etc.) you
#             would still need a booting Mac OS System to
#             apply the System Disk patches in case they
#             get screwed up.  So if you're the owner of a
#             proprietary Mac OS CD let this Makefile convert
#             it to a useful utility CD in case you get stuck
#             with stand-alone-linux on your Mac-Box.
#
# WARNING: The image given with BOOTABLE_MAC_CD will get
#          modified! It might not work, so do backups !!
#
# NOTE: You cannot compress your kernels if you want to use
#       them with BootX ;-(
#
# Tested on a Beige G3 with OpenFirmware 2.4, might work on
# other models.  Hopefully we will not need this anymore
# some day, when support for Apple's oldworld machines has
# grown up ;-)  Ciao ..
