OK, I just tried this proceedure

Code:
cat /dev/cdrom /mnt/hda3/iso/my.iso
using a newly knoppix-installer'ed PC (hd install of 3.8.1)

and I get these errors:

Code:
/dev/cdrom                     no such device or address
/mnt/hda3/iso/my.iso           no such file or directory
Do I have to mount the cdrom first? Is /dev/cdrom not the device that KNOPPIX 3.8.1 defines? I tried /dev/scd0 too as thats used during a liveCD bootup, still no joy.

Do I have to mount hda3 first? I'm already running KNOPPIX from hda3....

TIA,
AJG
