Question How to access DVD using Linux booted from CD?

Hope the title describes my need. In a nutshell, I have installed, configured and backed up Fedora 5 (using partimage). I copied the backup files to a DVD for safe keeping. When doing my "cold iron" recovery drill I needed to access the backup files on the DVD. So far I have determined:

1 - partimage will not read from a DVD (seems to be confirmed by discussions on the partimage forum)

2 - the Linux boot CD from g4l does not seem to be able to mount the dvd (nothing in /mnt nor /dev that looks likd CDROM or DVDROM)

3 - same issue with the Fedora rescue CD - tried /dev/hda, hdb, hdc, hdd etc. - no luck

4 - Knoppix will read a DVD however, as it is running from the DVD drive, I cannot unmount the Knoppix disk

My recovery procedure calls for installing the new hard drive, restoring the partitions using sfdisk and restoring the mbr. I then create a file system on sda6, place the backup files on this file system and restore /boot, / and /user from the partimage files. I scp copied the files from the DVD in another PC and it all worked. It would be nice though to be able to work from the backup DVD and not have to involve the network and another machine.

Any help or ideas welcome.

try this at the knoppix boot prompt:

knoppix toram

You will need about 828MB or more of RAM (enough for the iso and the memory used by the programs).

If you have less memory, try Damn Small. It's about 50MB (or less, for the floppy image), but can fit on a floppy (with minimal features), a CD (not sure if it can be copied to RAM), or USB drive.

Thanks StargateSteve! That did the trick. I can umount the Knoppix CD, load my backup DVD and copy the files I need to the hard drive. Hopefully I will not need to do this. I have had good luck with Seagate drives and I expect my new Barracuda SATA disk to last a long time.
