Can I make a TeenPup CD added to the Puppy 4 Dingo already burnt? Solved
 
http://www.puppylinux.org/wiki/archi...vative/teenpup

TeenPup seems to be better at youtube and java? Not sure
but anyway I burned a CD 700 meg with a 100 meg Puppy Alpha
that I don't need anymore so

Can I use BurnCDcc or something else to delete the 100 meg Puppy
and instead burn the TeenPup iso on it so that the original be marked
don't read and the new one get read at boot up?

hope I have explained it. I mean why throw away a functional
CD if it can be reused? Yes I know they are cheap but if it is
raining and far to the shop and they are not open and you have
plenty of time to play with distros. Would be handy to reuse it.

Could it be done and how do I mark the old one so it don't get read?

You can only reuse it if it is cd-rw (not if it is cd-r or cd+r).

I feared that but the puppy program reuse it again and again I mean do multisession on it
until there is nothing left. So it is just the start or boot record that is not possible to
x out and make a new such boot record?

So it doesn't help if there is two or three iso on same CD.

Does the BIOS only use the first cause the boot record only link to it?

My understanding of how cd writing works is limited.

If you copy data to a cd that is not rewritable, you won't be able to add data if you close the session - if you leave the writing session open, you can continue to add data to the disk, but the data from the first session remains, it isn't deleted.

I can't tell you the technical reason, but you can't have multiple isos on one disk. You could put the files necessary for a frugal boot of different puppy distros on one disk and boot them using grub, but not on your existing disk.

If you want to use and reuse disks, buy cd-rw (or cd+rw). Then they can be wiped and rewritten many times.

Yes and No!

CD and DVD works as you say if one finalize.

I have two DVD recorders for video TV.
They have built in TV receivers so I can see
all the channels. As long as I don finalize
I can shut down for that day and continues
some other day and add more tv shows.

Only after a Finalize is it not writable.

And I can delete shows and the only bad thing
that happens are that the show become invisible
to the software and to me. It is still there in
the groves but it is marked as deleted.

What I tried to ask what in what order the BIOS
read the added material.

If your curious in Puppy Linux multi-session CD and DVD

Quote:

So, when you boot Puppy, if tracks are read in reverse order and the latest version of each file copied to your home directory in the ramdisk, what about deleted files? Say you delete a file during one session, that has previously been saved to DVD at the last session, won't it come back again next time you boot? No, Puppy has a mechanism that keeps track of deleted files and this won't happen. However, that does raise an interesting point ... the deleted file is still on the DVD, meaning that every single file that ever existed will be recorded on the DVD, meaning that you have a perfect audit trail of past activity.
That is how Puppy do it but I ask how the Bios do it.

I guess theres a wiki or a Ms text somewhere on internet but I have not
enough fantasy to know which search word to use and even if I had the
writer of that text never thought one would need such knowledge either.

Barry who made Puppy wrote that it is a world first almost. Just one
group doing it before him and their thing seems not to be widely known
while Puppy is among the 20 most popular distros.

so if Bios do the same as Puppy does then the bios would first find the
newest added iso and use that one. that would be smart. The updated iso
would be the one given priority. But I fear that is not the case.

But you can add material that is what I do every day but I have no clue
on in what order it get read by the Bios.

To use rewritables. Barry write about them too.

Quote:

I do not recommend a CD-RW simply because it isn't necessary. A CD-R is "write-once", but in multisession mode, tracks can be written one after the other, up to 99 tracks or the CD-R becomes full.
I have four DVD+RW so I can use them to test isos with and when I find an iso I like I can use the 7 CD I have to save them forever.

Puppy's multisession capabilities has nothing to do with allowing you to burn multiple .iso images to a cd-r cd (have you actually tried this?).

The code that make the .iso boot is on the .iso image on the disk - the BIOS only comes into it to tell the computer the order it is to look at the various devices to boot from. As soon as it sees that it is to look at the cd drive first and it finds a bootable disk there, it boots from the disk.

The main boot record only comes into it when you are booting from the hard drive (or booting files, not an .iso, on disks).

Anyway, good luck with it. :)

And I quoted what Barry wrote about the order that code told the software to read.

To start from newest and take oldest last.

It even allow one to stop the boot and to prefetch commands from keyboard before
continuing.

So if Barry would change the distro of Puppy to allow for to skip this iso
and to go the newest iso or to display which iso are on the CD ro DVD and let
one chose among them.

A boot ino let you chose what OS to start with.

Could not a CD be made to ask which iso one want to use.

You can chose which music track you want to start with.

So I agree that it can be too late this time but that one maybe
can make an iso that allow one to chose among many isos?


But I know too little and have not tried it. Then I would not need to ask
how it works.

nooby 07-04-2008 11:59 PM

I tested and it didn't work for me.
One maybe could put a special thing first
that allow later to skip over.

One can have puppy400 and then tell
the boot to skip that one and to read
only latest that is a saved version of
puppy400 but not a totally other version.

So solved it fails
