This is going in the other direction of most people but I wanted to try it I haven't added much to it yet just distcc, blender and wings3d.

I burnt the image onto a dvd-rw and booted it on a laptop and everything works fine, now to start adding some big things like my 2 gig Unreal Tournament folder and see what the speed is like.

Anybody else try Knoppix on dvd?

Sounds like a great idea!!! There are alot of big stuff, flightgear map of the world....

That would be a great iso to put somewhere.

I suggested this to Klauss several months ago and he said it would run too slow!

I will keep adding to it and see what the speed is like so far its okay just a lag as the disk spins up.

I want to put some games like Unreal Tournament Demo but I would need nvidia acceleration and doing a search it doesn't look like its being done.

Any other suggestions for adding to it, big programs that won't fit on a cdrom.

I saw your post about Knoppix on DVD and REALLY want to get a clue how you did it. I have the small (80mm) 1.45Gb disks in my drawer and want to be able to get Knoppix onto one of them. I know it won't be as easy as burning a CD, but I am able to burn regular DVD's in WinXP. Any ideas for me? :!:

I created the image using the remastering how-to then I burned the image using dvd-decrypter under xp.

Dvd-decrypter is a great free program that will work when Nero won't to the job.

My later attemps using a larger compressed file system failed, I have to do some more testing to see if something got corrupted or if there is a size limit on the compressed file system.

I wonder if its possible to have more than one compressed file system on a disk and mount them seperately.

The bigger the image will get indeed,the slower it will get.
Isn't it possible to create then multiple img files and mount them seperately to accelerate it ?
I think by wisely deviding them (ex. each big game an img file) wouldn't it
accelerate things a little ?
Nevertheless using DVD's I think wouldn't demand a considerable amount of memory (read ramdisk ) extra to load the game.
In case of that extra memory maybe create more then 1 ramdisk ? A part for the system and a part for large gamefiles ?
Or is there maybe a trick on creating extra buffermemory for the DVD player ?
I think we'll have to wait for the new ATA standard.

It works! I have my Knoppix 3.2 on a 1.45Gb 8cm mini DVD. I couldn't get the DVD-RAM to work with DVD-Decryptor though. Is there a problem with DVD-RAM and DVD-Decryptor. I checked their site and there doesn't seem to be any info about it.

Cool, I don't know about dvd-ram I have been using dvd-rw's to play with this and they work fine.

Next I want to get the nvidia drivers working so I can try some games on it.

ALRIGHT!!! After my early failure with DVD-RAM disks I decided to try my new DVD-Multi Drive with a DVD-RW disk just as someone (mjd) suggested. Obviously it worked because I am running my system off the drive right now. Thanks again to mjd for giving me the information about the software (DVD-Decryptor) and the DVD-RW disks.

So the larger an image is the slower access to the image is???

I'm sure someone will be hacking on cloop to get rid of this issue. :)

Putting a standard Knoppix image onto DVD might speed up access though, as fast DVD-ROMs have a higher transfer rate than recent CD-ROMs. If Nx means the same read speed as it does write speed, than a 4x DVD has the same transfer rate as a 40x CD-ROM (approximately). Most modern DVD drives are 8x or more, and at least the 4X drives are CLV (or CLV-capable. The Pioneer DVR-105 records CLV - It maintains 4x for the entire disc when recording.) You might speed access times since the head doesn't have to seek as much on a smaller medium.

BTW, there are patches to cdrecord that allow DVD recording under Linux. Stay away from the dvdrecord project - Their mkisofs is horribly broken and dvdrecord doesn't work with Pioneer DVR-105s unless using media present in the 105's media table. ($$$). The patch against cdrecord 2.0 that I use is somewhere on www.crashrecovery.org

Don't know much about this matter, but why would you need DVD-Decryptor to copy to a DVD-Ram? I just drag/copy-paste in WindowsXP.

OTOH, I've never managed to get Knoppix to use a DVD-Ram...
