How Can I Mount a ISO Image CD ?
You have an image of a CD or perhaps of a floppy disk. You may have downloaded it, or created it by reading a real device with “dd”. Now you want to mount that image. You could write it back out to media and mount that, but that may not be convenient or even possible at the moment.
If you are using Linux, the “loopback” device is what lets you do this. It can be as simple as:
mount -o loop -t iso9660 filename.iso /mnt/iso
but it can also be more complicated if you instead have a dd of a disk: see http://talk.trekweb.com/~jasonb/articles/linux_loopback.shtml
