Super-Disc: Multi-Boot Project CD/DVD Using ISOLINUX

Recommended Posts

Thx

I will try when I am at home.

EDIT:

It works so far.

I copied the files.

I copied and renamed the isolinux-folder to \custom\ubuntu

I added the following lines to mymain.cfg:

LABEL ubuntu
MENU LABEL U^buntu 7.04 LiveCD
KERNEL vesamenu.c32
APPEND /custom/ubuntu/isolinux.cfg

But the Ubuntu-menu is now in default-vesamenu. (grey background)

Of couse I could add

MENU INCLUDE /custom/mydefs.cfg

to \custom\ubuntu\isolinux.cfg to customize.

But I want the original menu.

And I cannot change the language (F2-key) in the "new" Ubuntu-menu. :(

I think \custom\ubuntu\bootlogo is responsable for the ubuntu-menu, but i didn't find out how it works. :(

EDIT2: I forgot to say.. There was no "boot"-folder on the Ubuntu-CD.

I think you misunderstood me. The default menu for Ubuntu uses something called gfx which isn't the same as vesamenu.

You don't need the original isolinux folder from the Ubuntu disc just the isolinux.cfg file. Open it up with your favorite text editor and copy the relevant commands to your menu. If you require extra options like languages you'll need to add them to your menu as well. You can find the extra options in the F*.txt files (* representing an F key number).

I understood you.

i just copied the isolinux-folder, because I though I need it to get the original menu.

There must be a way to start "gfx" from isolinux,

but I have no motivation to deal with this. :)

I will use my own Ubuntu-menu. :)

But how can I set the language in the bootcommand?

The F*.txt-files don't help.

They are just for the help (after pressing F1).

And I cannot find a command like "lang=de" or something.

Anyway, this is not important.

I will concebtrate on other things. :)

Sorry about that, I never checked it before posting :blushing: .

You are correct though, there doesn't seem to be any params for language selection. I can only assume it is performed on the fly, might be something to do with gfx or should I say gfxboot. There is very little written (that I can find) about this menu system so I can't really comment.

A final word on this:

ROOT # mkdir /tmp/initrd; cd /tmp/initrd
ROOT # gzip -dc /initrd.img | cpio -id; ls

With this little snippet, one can open up the init ramdisk and at least look at the linuxrc script, to better understand the boot initialization process.

Ultimately, that's the principal point I've been emphasizing throughout this thread. That is, to open up the underlying components and figure out how they work to realize a custom solution. Not just for the immed issue, but for helping in future efforts....Jet

This topic of gfxboot has got me interested in it again, the only problem is I can't even find a home page for it let-alone any docs.

According to one post in the syslinux mailing list "it's uglier than hell to configure" but I still think it looks and performs better than vesamenu.

If anyones up for it could we possibly look in to this and try to pool some information for guide?

I'm nearly finished with my migration to Ubuntu (I just need a few more apps for specific tasks) so I'm gonna take a look at the UCK - Ubuntu Customization Kit that Jet was talking about, since it is supposed to handle gfxboot customisation.

If I learn anything I'll post it here.

Sry, abandoned the gfxboot idea again.

New syslinux pkg is out with some good updates to vesamenu that negates me switching.

If your a Ubuntu (or deb) user I've found a better prog to UCK... Reconstructor.

From what I can see this prog was used to create parts of Linux Mint, which is also worth a look.

Later.

I've finally taken the plunge and moved from cdshell to isolinux but the problem I am having now is that I am getting an error when trying to load dsl 3.3 (3.2 no longer available).

Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.

I've followed your instructions exactly in the original post. The original dsl iso boots fine.

Can u post your isolinux.cfg or any other config file thats related, your disc structure (just a representation), and how your creating your iso i.e. cdimage, mkisofs, k3b, nero (god forbid) etc.

I'll dl DSL now and see what I can find out.

Edit: Tried it out with no probs.

* Copy KNOPPIX dir to root of your disc.

* Copy linux24 and minirt24.gz from /boot/isolinux/ (on DSL disc) to a dir of your choice (on your disc), I chose /isolinux/dsl/.

* Assuming you've used my locations add this to your menu (without **** and word wrap):

LABEL dsl
MENU LABEL **** Small Linux 3.3
KERNEL dsl/linux24
APPEND ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 initrd=dsl/minirt24.gz nomce noapic quiet BOOT_IMAGE=knoppix

* Create image. I used K3B for this but if your in Win then I suggest cdimage or mkisofs.

Done

I use the following command to make my ISO

The disc boots fine and everthing works except for the message about the filesystem not found for dsl.

Your locations and commands seem fine. The only thing I think could be causing u a prob is mkisofs. Try adding joliet to your iso.

Sorry to be abit vague but I personally never used mkisofs to create images. In Windows I used cdimage and now in linux I use K3B (which uses mkisofs... sort of).

The reason I say try adding joliet is I remember reading somewhere that your need it for Knoppix to boot and since DSL is a small ver of Knoppix...

Sorry I did say this earlier but it just dawned on me!

@#$%&@#

So **** simple. Just added a --joliet to my command line and it now all works.

The reason I'm using mkisofs is that I'm building this iso on a mac.

Thanks man :)
