+#!/bin/sh
+#
+# Script for making a memtest86 boot floppy using GRUB as bootloader
+#
+
+# (c) 2003 Peter Loje Hansen <pl@2m.dk>
+#  - original version
+# (c) 2004 Yann Dirson <dirson@debian.org>
+#  - added parameters
+#  - ability to work on a floppy image instead of a real floppy
+#  - adapted patches from Martin Koeppe <martin@koeppe-net.de>, to use
+#    mtools and install full grub
+
+# TODO:
+# - add a flag to generate a default boot entry for (hd0)
