    I know i am a noob when it comes to programming but wouldn't it be possible to design UBCD4Win so that one could put it on a pen drive, or even design it so that when a person puts it on a RW cd or dvd that it would save the information or software defs or soemthing that does not get saved to the RW.


    just an idea

    sincerly,

      Good ideas.

      USB has been discussed in a multitude of threads.

      RW's can't be used as most systems can't see them for booting and plus the project needs to be finalized and so thusly no more writing to the disk is allowed. I am sure that other people have the exact reason but the above is in lamens terms as to why.

      DVD's are also a very slow boot as the system has to read the whole disk prior to launching. They can be used but again you can't write to the disk that you are booting from while in the project.

        This is incorrect information. It's actually better in most cases to burn to a CD-RW when you can (unless you're going to use it on really old system) as you can then update the CD easily and not always use a new one. And YES, you CAN finalize a CD-RW and then erase it later. I do it all of the time with no problems. :)

        As for DVDs used, as long as you're not using the entire DVD then the system doesn't have to read the whole thing (actually I don't think it has to read the whole thing anyway). It would only read the section where there's actually data (which in some cases may be only 1GB, and not the full 4.3GB). As long as you have a decent DVD-ROM drive, there shouldn't be any problems. :)

          What about using DVD-RAM? :P

            Version 3 already has DVD-RAM support added. There are methods to use a cd-rw also & add files to the current booted cd with growisofs.exe, but requires a special version of mkisofs.exe.

              Again I thought I put all the words that ran through my mind onto the page... I meant that he can't use RW's and continue to write data to them while he is booted in the project. It won't let you. RW's can be used to make it and test but not all systems will use it...

              The DVD stuff... I don't have the luxury of having a DVD burner. I remember reading a while back either here or somewhere else that using DVD's is very slow as the drive reads the whole disk for some reason and it slows the boot to 3 or 4 times longer than it would be on a regular CD even if the data is the same and was just burned to DVD instead of CD.

              anyways....

              My apologies for supplying incorect data.

                Most of this was CORRECT, but has been SUPERSEEDED by new methods created by people that don't sleep at night. :)

                This was accurate untill about 3 months ago, maybe less. There is a way to create the iso with a special version of mkisofs.exe & then add files to the same cd with a program called growisofs.exe. This whole approach is new & still experamental, but very interesting. The same works for dvd-rw as far as I know. The downside to doing this with any bartpe build is that the system "hangs" directly after adding the files to the cd, but the data is written corectly & all you have to do is re-boot. This will add new functions latter down the road as more time is spent understanding how these options work.





                As for the DVD stuff. We added driver support for dvd-ram & although I don't posses the hardware to test this, have been told that you can easily add files to the same disk you booted bartpe on.

                  well it is only an idea.

                  I just suggested it becuase some linux software (mepis or ubuntu or suse) had the capability to save information to the live cd-rw itself.
