Very simple...the Editor...it dissapeared as it came...i guess people even forgot about it.

Very interesting thread.

I've been working on my Kronos-88 for sometime, I like it, however, I've been desperately wanting to change the set-list (or combi) to not-stop the rhythem when changing from one program to another, otherwise, the keyboard is almost useless and boring when it come to live-performance to work on it's own in a stage.

I tried speaking with Support, but the person there keeps bouncing me back and ignoring my requests to enhance the keyboard, I mean at least make the ENTER key useful when working from a menu similar to EXIT at least!... Seems to be hitting a dead-end.

Now, with my background of machine-coding, here is what I've been doing:

1) I removed the internal HD out, copied it into another HD for testing on another machine, and then returned it back, that went quite well.

2) In a non-destructive way, I have mounted this hard disk onto a virtual machine on my laptop, modified a lot of OS stuff, and now into checking how to access the additional encrypted file-system that is not mounted with the normal scripts.

3) I have extracted the bzImage and looked at the Intel code (seems standard to boot linux all over), not much there, moved on...

Under /etc/mnttab they seems to have removed the shell from booting up, which restricts the CPU to only deal with the keyboard and ignore the OS/shell, which is great for the keyboard. Also they have changed level-3 to only run from the OA.si file which seems to be doing everything to get into the fully/booted mode.

4) Looked into OA.si and modified a lot of it to allow some services via ethernet.

Now: Destructive-way (Please do not do what I am doing, as I cannot be responsible if you damage your system):

5) By default, the /etc/sysconfig/network-scripts contains the if-ethXX, which are set to use DHCP, I modified these to use a static IP.

6) Drilled the buttom (wood base) of my Kronos and fitted an RJ45 socket, which is then connected to the internal motherboard via the Ethernet cable, it looks great now.

7) Booted the system, and now can see the FTP server listening, can't access it yet as i don't know user/pass yet.

8) Tried to alter /etc/shadow, and /etc/passwd files, to add another user (myself), however, doing so, the (SHARK) system is picking this up and stopping the boot-process saying "Incorrect files etc, re-install the system... as such".

9) I tried modifying the vsftpd.conf to make the ANON user starts from "/" rather than the locked-up location, the SHARK is also detecting that these files are changed and therefore preventing the Kronos from booting up.

It seems that the SHARK system is not only mounting, but could possibly be doing a check on the /etc file-system to see what's been changed, if any, then it would not boot. Or perhaps the script is doing this check by itself, sooner or later, I will find out...

10) reverting back the files under /etc (shadow, passwd, vsftpd.conf) all seems to work fine.

11) Yes, the SHARK (as you defined it) looks like a USB device that sucks it's data from the bootable Linux kernel, which is what I am trying to get into to see if I can modify some functions to make my Kronos more useful after giving up requesting this from Korg.

Going back into my non-descructive VM, I can see that the OA.si is only loading up 4 drivers (no more), I added more support for other hardware (such as VM-SCSI, VM-NET etc), and now it looks better.

Theoretically, I should be able to unplug SHARK from Kronos and boot it up from my VM and then take it from there.

At the moment I am stuck trying to unshadow to get the root password out, I am using john at the moment which seems to be taking some time.

I thought about contributing to this thread, as I would like to put 2 heads together to see if there is any room to enhance the Kronos as I do like it, but can't use it yet in live performance due to original design-flows, which are driving me bonkers!

With my time restrictions for working on other stuff, I will continue working on this in a week or two.

Please bear in mind, that I am not trying to harm Korg's business in any way, all I am doing is working to enahce my workstation to use it the way I bought it for, which might in turn boost their sales of the Kronos if it can be enhanced a little more, I am not in any way sharing any code, nor source-files, I am happy to stop digging if Korg are willing to enhance their workstation themselves by listening to all my open support cases, and do something about these enahncement requests that no one seems to care about.

I will come back later in two-three weeks time if I have managed to change something later.

Regards
Heider

Thanks Roblof,...

Although writing a script sounds like a fantastic idea to me, I'm sure it would work fine on the VM, however, with my experiment with the keyboard today, it seems that all files under the /etc folder are either size-checked or diff-checked by Shark (I think), well, at least I know for sure that shadow, vsftpd.conf, passwd, OA.si, etc is already...

Which leaves to do the work on the VM connected into a USB cable to Shark, I think it's the best way forward.

With the RJ45 port mounted on the bottom of the Kronos, I think I might be doing more, I am thinking of buying a USB+VGA KVM from eBay to share the Shark system between the Kronos and my VM. Who know, the Kronos might run later from DOS or even Windows for a laugh

Anyway, I am about to order something on eBay and wait for it,...

Thanks for the brilliant idea by the way, I think if there's room to implement it (some non-checked existing boot script), then it would be as follows:

1) At startup, copy the original files into /shadow and /passwd (overwrite them with originals).
2) After a while, modify these files with a sleep-script with the ones that contains additional users.
3) Connect and see...

The reason for (1) above is that you don't want to cause the Kronos to work for one time only by copying the changed files after the first boot and then the system fails to load after restarting the Kronos !... Anyway, might try this tomorrow, it's not safe to try it now in front of my kids have to wait...

Cheers,
Heider

I don't know about the editor, but I think this thread lost it's way.

New thread about the core stuff started due to the hijack of this thread:

I see you guys thinking how we can change our Kronos.. What you should be thinking is how we can add the Kronos to our current PC.. If we cant replace the CPU to make it 64bit? Why not extend the cables to our current i7 core systems and use our 24" monitors for the display.. Could even replace the main board with a newer one.. Almost reminds me of a monther board thats for a tv pc.. Like I have seen these little boxes that are ment to hook up to your HDTVs.. If I remember its an idea that kinda flopped and Intel found a way to dump them.. HAHA
