Hi There is a bug in patch-floppy-image.pl. I tried using it as it is documented : ./patch-floppy-image.pl 'root=/dev/hda8' boot-floppy-hfs.img > boot-hfs-hda8.img but this gave me an image 1 byte smaller than the original. I fixed this by deleting 1 space from the line: my $current = "root=0200 ..... "; which is 99 character long and not 98. The length was broken in version 1.4. Regards Lars Munch
