you just might want to basically roll your own. how you do so depends on the
device you're working with.
as an example i'm working with a device from ZFlinux, it comes with a
document that explains what i need to do. basically i compile my own kernel
and create a compressed initial ram disk (initrd). the document explains how
to inject these items onto my flash disk (requires a special dongle and
mswin). i power it up... and voila! a running linux system.
for this particular system the kernel itself can't be larger than 500k and
the filesystem can take up the rest of my flash disk. i'm using a 4MB flash
disk and 8MB of RAM. my working system (kernel+files) takes up only about 1.7
MB of flash space altogether. don't worry about the kernel constraints, you
can always compile modules and have them loaded in afterwards. the basic
kernel core should easily fit inside 500k. i'm using 2.4.18.
in your case you're using a compact flash disk. i've never used those before
so i can't offer too much help. my understanding is that they appear to the
OS like a regular hard disk. i also understand that there are cables and a
board you can get that allow you to connect a CF disk to your regular desktop
system's IDE connectors. maybe you can do that, copy over the stuff you want,
insert a kernel (+modules), and run lilo on it. that's just a guess, however.
there are also lots of good articles around that will give you additional
tips and tricks. if you haven't already found these resources, you should
have a look at:
1) http://www.busybox.net
2) http://www.uclibc.org
3) http://embedded.linuxjournal.com
4) http://www.ddjembedded.com
5) http://www.linuxfromscratch.org
6) http://www.linuxdevices.com
hope this helps. best regards,
