I don't know of any embedded devices that include support for Compact
Disk media.

To avoid confusion for you an others developing natively for x86 based
devices.. I'll quote from another mail I sent out this morn.
------------------------------------------------
Booting livecd's is not necessary.
Being that you develop for x86 as I do. You don't have any of the cross compile hassle.
It in fact does not even have to be done from a gentoo box in the first place. 
Simply decide if you want/need the extra security features (highly recommended in networked environments) unpack it to some directory such as.

mkdir -p /opt/i586-gentoo-uclibc-linux/usr/portage

wget http://gentoo.osuosl.org/experimental/x86/embedded/stages/stage1-x86-uclibc-hardened-2004.3.tar.bz2
# or 
wget http://gentoo.osuosl.org/experimental/x86/embedded/stages/stage1-x86-uclibc-2004.3.tar.bz2

tar zxvf stage1-x86-uclibc-2004.3.tar.bz2 -C /opt/i586-gentoo-uclibc-linux/

mount --bind /proc /opt/i586-gentoo-uclibc-linux/proc
mount --bind /usr/portage /opt/i586-gentoo-uclibc-linux/usr/portage

chroot /opt/i586-gentoo-uclibc-linux/usr/portage /bin/bash --login
nano/vi/$EDITOR /etc/make.conf ; # (change what you like like CHOST=i586)

cd /usr/portage/scripts
./bootstrap.sh -p -v ; # make sure everything look peachy.
./bootstrap.sh
# after 
emerge -e system
# now you have a complete development environment setup.

Now you are ready to begin building optimized packages or whatever for
your device.
I enable FEATURES=buildpkg 
I then install these packages into yet another root via
ROOT=/dev/shm emerge -K busybox uclibc ; # and cleanup the target root
of things you don't need for runtime.

These steps can be automated.

mutext@g.o builds for his device via the catalyst tool and posted some
getting started instructions to this list not so long ago.

I do not understand this question. Can you rephrase please?
