# Script for making a memtest86 boot floppy using GRUB as bootloader
#

# (c) 2003 Peter Loje Hansen <pl@××.dk>
#  - original version
# (c) 2004 Yann Dirson <dirson@××××××.org>
#  - added parameters
#  - ability to work on a floppy image instead of a real floppy
#  - adapted patches from Martin Koeppe <martin@××××××××××.de>, to use
#    mtools and install full grub

# TODO:
# - add a flag to generate a default boot entry for (hd0)
