Hi

I'm trying to add extensions to a liveCD DSL. I believe from the readme I need to add the files to the root directory of the CD, but I'm not sure what I then need to do to burn a bootable CD (that will automatically install DSL).

I currently use Nero (6.3) under Windows to create my CD's. Is this suitable?

Thanks

Ric

yep, you need to edit the iso and add the extensions, add them to the root of the iso if you want them to autoload or in a directory named optional to have them as options.

Or, burn the DSL iso image to your CD in multisession mode, leaving the disk 'open'
then burn a second session with the extensions you want LOADED in the root
of the disk, and the ones you want handy, but NOT LOADED, in the /optional dir.
This requires no special software to "rebuild" the .iso , and works just the same.

O wise Ico2, what Windoze app allow one to edit the iso?

You can't "edit" an iso. you have to rebuild it.

-go get cdrtools (specifically mkisofs)

-now get winimage (shareware) or filedisk (GPL)

-do one of these:
a- use winimage to extract the base files from the ISO (double click the iso file once winimage is installed),
b- mount the iso with filedisk

Code Sample

filedisk /mount 0 c:\temp\dsl0901.iso /CD f:

-copy all the files from the CD to a temp directory.
-copy your @boot extensions to the root folder of this directory
-copy your optional extensions to the optional/ folder of this directory
-run the following command:

Code Sample

mkisofs -no-pad -l -r -J -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o mydsl.iso [i]tempdir[/i]

Ta-Daaa, you have a MyDSL ISO. go use nero or something to burn it.

The best windoze app I know of is "ISO Buster". Not sure where I found it, but it works great for ISO's (hence the name....):p

I think Ke4nt has stated a simple method which works. However there are some problems about configuring the desktop etc and adding some plugins to the firefox browser.
The firefox_plugins browser is in the /ramdisk/opt directory. Thus to create and add your own firefox_plugins hidden directory you have to
edit the ISO
or
add a script to the root directory along with your own firefox_plugins directory, which, on bootup will copy this and paste it over the /ramdisk/opt. Now when we start firefox, most plugins will be available.

Is this possiible?
