You will not be able to mount hda7 if that is where your PMI is. Knoppix locks the partition where the PMI is installed.
Hi,
I put KNOPPIX.iso on my fat32 partition(hda7), and when I boot with
bootfrom:/dev/hda7/*.iso KNOPPIX boots ok. but I get message when
try to mount hda7: ACCESS DENIED TO /CDROM2.LOOP
and also my CDROM is locked.
Please, any suggestion!

Thanks,
I also tried tohd: and fromhd: with full path but I get boot problem message that file system didn't find.
