I might not have to de-solder the flash if I'm lucky.

Since shark is arm-based I can utilize jtag together with openocd. This way I can also run gdb.

I'd like to have dtrace on mobo + add a few extra helper programs on the mobo as well.

With the working network stack gdb would be good to use as well on the mobo.

Oh, thanks God for not de-soldering... I would definitely be very nervous to try anything that can't be undone easily for the £3000 machine !...

Anyway, what I did to mine was to:

1) Install a new VM (Ubuntu x86), and then use that to
2) Connect the Kronos disk into the VM, and then take a snapshot (zipped it also to backup just in case).
3) "apt-get install" all the missing debug programs onto the original Ubuntu, and then:
4) Just copy the /bin and /usr/bin (without overwriting anything) from the Ubunto into the Kronos Image, things like strace, gdb etc,

I was quite surprised, they work! even if the OS is not the same, it's still Linux !

Now, back to the update...

Watch out for:

1) Improved the INT 13h compatibility.
2) Fixed issue with SCSI install failure.
3) Updated mini-PCIe to SATA bridge option ROM.
4) Fixed issue where large hard drive size is displayed wrong in BIOS setup.
5) Add support for Promise Technology* SATA Card in CSM16.

If for any of the above items causes Linux to read the disk as an HDA rather than SDA (INT13 fixes to functions 42xx), then the Kronos would "Kernel Panic", or causes the upper part of the HD (almost half the HD disk's geomery to be read differently causing corruption), you would know if something goes wrong, once upgraded, if booting is good, then great, use the "disk" button on the Kronos to access the file system to ensure that it's not showing any of the files as garbage, also ensure that they load and play fine. I'd personally am willing to talk to the upgrade risk to see if it would work and what would happen, but be extra careful to take backups in case you need to revert back to...

6) Moved the Int05h, Int17h and Int74h code to E000 Segment in CSM16.

I've never personally had to use int-17 (printer API) myself, and don't think Kronos is doing neither, however, Moving code away from an original location into E000 segment might cause some functions (if called) to hang. That is only-if the Kronos was coded to have the protected-mode driver doing direct calls into these locations, again, highly unlikely to cause issues there.

Below should be minor to worry about:

7) Disabled IGD when PCI VGA exists and Primary display adapter is set to external PCI Graphics.

The reason is the IGD (Integrated Graphics Device, i.e. onboard one) might be disabled, since the LCD is SHARK-mounted, then there should be no problems there, only small worry just in case your primary display (VGA) goes disabled. That's all.

I would go ahead with the upgrade, and will do myself later on... but first, I would really like to come up with something nice (some test screen the least) embedded in the IMG files, currently, I'm just reading and understanding the code.

Oh, not really a big problem. I've done it a couple of times before on other stuff before to restore from corrupted firmware.

However I don't want to open/cloes my kronos too many times since the screws/holes wares out....

I'm envious about all space you have in your kronos. Mine is a 61-key and space is very tight at the mobo

/--R

Posted: **Sun Jun 10, 2012 6:34 pm**

Well, when I opened mine, I noticed a space also just above SHARK for ports to place, I didn't want to drill there for the fear of any drilling-metal-dust which can short-circuit SHARK, however, using my hoover, I managed to drill the holes successfully whilst the hoover is on at all times. I am sure on the K61 you can do it too but it wouldn't be at the far-end, perhaps in the middle just above SHARK, I think placing the Kronos upright can ensure that no metal particles drop there.

All you need is a drill (don't drill fast, just very slow to do a precise job), and a 23mm metal drill-piece (less than £10 from eBay), and also these sockets, they work great, and saved me heck of long time to (as you say) open and close the Kronos...

In the worst case scenario, perhaps buying a Ply-Board from Wickes or B&Q, cut it into the same size of the original, and then drill it to run the cables/connectors might be a good idea to save time, this way you keep the original board, and only place it back when all this is done.

I noticed on Linux there is a tool called WireShark, (funny name, quincidance? I know...) this tool can be used (if you are into Linux more than DOS), to debug all USB signales (kinda like net/usb-mon)... The bummer for me is that this tool requires a GUI, which means that I can now install another VM for a GUI-type Linux...

Anyway, flying tomorrow, gotta pack, .. gotta pack, .. gotta pack !!!...

I hope this puts a smile on your face

All the work is being done from OA.ko (from within Mod.img), it's all there, menus, APIs, forms, etc,

Once I come back from my trip in 10 days, you bet it's DEVelopment time...

Please don't de-solder your chip, I managed to read it from normal APIs.

I also have the content of the Eva file above, in ELF format, all done.

... as Adam Richmond (Man Versus Food) says "Ouuuh my Goodness, ... Ouuhh,... my,,... Goodness"...

What do you think?

Kind Regards
Heider

Posted: **Mon Jun 11, 2012 8:51 am**

But then I have nothing to do and have to wait until you come back

I don't think I can wait that long, or can I....?

I assume that the firmware is in the NAND directory.

Posted: **Mon Jun 11, 2012 9:02 am**

Hi Roblof,

The OA.ko file is the one to go into, it does the lot, which is (I think) what I'm interested in...

Anyhow, here is the contents of the NAND dir since you asked:

Think of the above as the "Firmware UnZipped"... therefore, there is nothing to Unzip. as SHARK load these files up.

For your info, SHARK does not do it itself, it actually ask LINUX to do the job, so the FS/IO is all LINUX based, it loads up the Module, once you are half the way down the startup screen the Mod is unmounted to ensure that no one (apart from me now) accesses this directory and read it's contents.

It's all in the OA.ko file, the rest is just resources loaded by it.

EVA is not that important to the Kronos, as it's resources to use and not codes/menus etc.

I hope this explains it.

Heider

Ok, I see....

Well, I'll have to try and decrypt the dirs then since otherwise I have nothing to do.

Aren't you on your way to the airport now or are you posting mobile

Posted: **Mon Jun 11, 2012 9:53 am**

Last post!...

About to get in the car.

... I hope Korg is not waiting on the other side of the Airport

Once question for you, which might be very helpful, before I get my hands dirty in it, have you managed to get Telnet/SSH workng on the Kronos?

Have a good day, I'm sure we'll talk later.

Heider

Posted: **Tue Jun 12, 2012 7:51 am**

Nope, not yet.

I've been too busy with my IRL + gigging stuff so time has been constrained. Also, doing this with a 2yrs old kid in the same room isn't going too well

My idea is to replace ftpd with sshd and hope that the kronos doesn't detect the swap

Posted: **Tue Jun 12, 2012 8:11 am**

(can't sleep... I've been awake since 3am US time now, I guess jet lagged)...

Don't worry roblof, I know how it's like with the kids, I got 2 myself... !

Anyhow, I already started patching-up LoadOA and InsMod files to allow me to run with modified /etc files. I think I will extend that later on to allow the rest of the /etc files to change without it stopping the loading process.

I really wish I could sleep, I feel extremely dehidrated at the moment, don't know why I forgot to buy water today... the tap water tastes like sand

but hey!...

When I was on the plane, I have managed to understand the format of the KORF file (something you would see when you decrypt the images), I now know how it's compiled and was about to extract all the images (buttons, BMPs, forms etc), until my battery ran out on me, I was gutted... but nevertheless, it's all in my head, will be done at some point once I'm done and on my way back...

As they say here... "Have a nice day"... talk to you later mate.

Kind Regards
Heider

If you could send me a patched version it would be a big time saver...

I'll try to spend a few moments with my kronos today, but tonight I have a rehearsal with my band so I can't fool around too much with it.
