I'd like to try and clone my Z .. (once I do a few more tweaks) and create a security based ROM. My Z has been rock solid stable for the past 6 months. so I was toying with the idea of making a ROm image for it. but I can't find either of these tools.
Let me know if you know of a mirror still up that has them... or if you have a local copy you'd like to post and share that would be great!

Hi,
I do not seem to be able to find the actual binary for Romburst, but you can get the source code from here:
Ian's Zaurus Hacking... (http://www.cypherpunks.ca/zaurus/)
It is down on the bottom.
I have also saved a bit of "extra" text, probably from a digest message, which may also be of some use:
Hey lazyate,
If all you're trying to do is extract the contents of Sharp's ROMIMAGE file there's an easier way. Try the following commands.
To extract the kernel:
dd bs=131072 skip=6 count=8 if=ROMIMAGE of=zImage
To extract the file system:
dd bs=131072 skip=14 count=128 if=ROMIMAGE of=initrd.bin
Hope this helps.

HTH,

Exactly what I was looking for
So I should be able to clone my current system with those commands. (as long as it isn't bigger then 22Mb to brick a Z)
Thank you VERY much ;-) I still need to find a compiled romburst to take out stuff I don't use. (like the todo and calander since I use KO/PI for both)
Now starts the dangerouse part of not bricking my Z with the now virtually extinct Sharp tech support :-p I think i'll start after midterms.

Ummm, I think modzaurus and romburst only work for the 5500...
I've never touched them for my 5600 ROM, and I don't think they *will* work, as the 5600 has a different filesystem (jffs2 as opposed to cramfs).
For a 5600 it's a bit of a more complex thing to explain...

not what I wanted to hear ... :pbut alot better ot hear now, than after i broke my Z ..... so thanks for the heads up.
I"m looking for an easy way to clone a Z. (without just distributing a tarball ..) I remember there being some scripts for OZ to do this ... so it should be accomplishable on a sharp based rom as well ..
I've got aa fiar bit of fun apps installed:: and I'd like to make a little ROm with them all, and some custom icons and things.
Chaos ... send me an email if you've got some free time, or catch me on AIM someday for a chat about 5600's.

It doesn't just work by cloning a ROM, often you have to start with the basic root filesystem and add onto that... And it's a pretty painful process when you first start it.
You can probably find me on AIM some time (ChaosVampireLord), and I might be able to point you in the right direction.
Also remember, for everything you add, you'll have to remove or compact something else... (i.e., I compressed the tar files containing the default /home, /dev and /var to make more room for apps.) So you can't just take the default ROM and add a lot too it. If the initrd.bin when built comes to more than 23 MB EXACTLY, the Zaurus will refuse to boot until you flash a different ROM image.
