Hi David, have you sure the copy is correctly downloaded?
You can test it using the follow command (if you have the iso file on the PC):
md5sum openmamba-livecd-it-milestone1-1.1.i586.iso
And to check that you’ve correctly burnt it: (assuming your CD/DVD reader is /dev/hda)
dd if=/dev/hda bs=2048 count=360036 | md5sum
in both case the result must be:
