Let's make something clear here ...
You have already managed to install Kronos resources , so DVD drive is not your issue , any working compatible motherboard
also is not the issue here !
Your main and only issue is that you can't re-authorize your Kronos because both Mobo and SSD ID have been altered and system
gives false validation anytime you restart Kronos and you have to provide validation anytime you restart for ever ...
This happens under my experience in the following cases :
- If you clone boot SSD of Kronos 2 and try to boot it in a Kronos 1/X
- Just the reverse case
- If you upgrade modo and use older DVD resources , have not tested the case of downgrading mobo though !

Hope this helps

"And there was much rejoicing"

Thank you Antony, Pedro, GregC, Voip for your very appreciated help.
Antony; major kudos for uploading the Kronos2 DVD's and giving me a place to download them.
As you can see by the screen shot, I am updated to 3.1.2 and all is working as it should.
I'll try to summarize the main issue in case anyone else runs into this problem.

- Tried to do a full install / format on, what I thought, was a Kronos61; 1st edition.
- Install seemed to go fine until initial boot. Using original Kronos DVD's purchased from the Canadian Korg reps. A two DVD set. Halfway through initial boot, received the "19,keybed" error. The screen shot below is a monitor hooked directly up to the MOBO. It says OA.ko failed. I'm assuming OA stands for Oasys and it's a Linux driver for the keybed.

- After checking all the connections, new RAM, new SSD (Which wouldn't install either. That's another story that's briefly discussed in this thread. Just wouldn't accept the Auth code. But I digress.) it still wouldn't boot.
- With the help of the fine Forum Mavens, it was determined that my Kronos61,1st edition actually had the MOBO for a Kronos2 installed in it.
- I downloaded the 3-DVD set for Kronos 2. Installed 3.0.1 using a plain jane LG DVD portable 1-ported USB drive. (Not 2-ported, ******. Sorry. I shouldn't name names. I'll replace the name with asterisks) and there was the Kronos.

I think that puts it in as short of an explanation as I can. So now that I have a Kronos1-61 body with a Kronos2-61 MOBO; does that mean that this is a Kronos12?

you deserve a Korg gift certificate for perseverance.

Did you talk to the genius that jammed a K2 mobo into your K1 ?

What was going on ? Was he tweaking the K1 or was it a legit old mobo failure ?

The guy I bought it off of said he had the SSD replaced three years ago. But I'm thinking they did the MOBO as well and he just wasn't aware.
But it looks like it's never been replaced. It's a pretty clean switch out if they did. Usually you can tell. You see little signs that something was retrofitted.
I dunno.

Maybe the repair tech ran out of D510's and said "$%^& it..throw the new one in." Could be a Tech Service Note from Korg saying "We have no more of these. Use the 140D's and the Kronos2 install disks. Cuz we sed so!"

Did Korg Canada do this 'service ' ? Was the 'repair tech ' from there ?

Not sure. But I can certainly find out. For curiosity's sake.

Yep , since you've purchased EXS 17 & 18 IDs, apart from wooden sides , now you own a Kronos 2 ...
Also use DVD 3 resources for extra PCG files of Kronos 2 if you need them !

I'm dealing with the same "19 keybed" error on a K2 after I replaced the power supply... kinda weird. Anyway, since I wasn't able to find the right ISO images on Korg website - I guess the Accessory disks images are for the original Kronos, but I could be wrong - I did some research and I found this website:

https://gerenm.net/kronos-accessory-dvd-rom-images/

Right now I'm downloading the "disks shipped with Kronos 2 (purchased Oct. 2020)", keeping my fingers crossed... They are labeled KDV-012B, KDV-013B and KDV-014B. Are these suitable for Kronos 2?

Yep, that's what I see written on my K2 DVDs as well. Hope it solves your problem.

I've just finished the installation from the freshly downloaded DVD set (OS 3.0.3)
After the restart, on the VGA monitor appeared the BIOS screenshot. I set date and time then F10-Save & Exit. Reload... and after about 30 seconds Error 19 once again Sad

After a short break I switched on the K2 pressing Locate and Pause, as suggested by Qqquartzzz, and I saw this message on the VGA display:

[1190] /sbin/insmod: Process status error 1
Insmod /sbin/OmapNKS4Module.ko failed
Error: cannot open framebuffer device. 19

Guess it's time to check out the OMAP board... (KLM-3002 on Kronos 1st gen, KLM-3360 on K2)

Update. I was talking with a friend about this issue and something he said gave me an idea: disconnect certain plugs on my working Kronos, then boot it to check which error would show up (consulting the service manual and taking great care, of course). After some unsuccessful attempts, I pulled off the three-pin plug that connects the digital board KLM-3006 to the motherboard: bingo, error 19 keybed!
It's indeed the serial bus connector for all controllers: keybed, joystick, ribbon and switches 1-2. Next step is to check if the serial data from the controllers are coming out from the digital board (page 22 of the service manual): it's the first time I try it and I need to learn how to... anybody could help?

PS Actually the digital board in the Kronos 2 is labeled KLM-3364; it's very similar to KLM-3006 except for the "Panel-L" connector that has 6 pins instead of 4.

Further update. The data from the controllers' serial bus are sent from both Kronos. I connected the bus to my laptop through a RS232-to-USB interface cable, running CoolTerm: no readable data, of course, but as I moved the controllers the data flux increased accordingly... I guess that means it's ok Wink
Then I measured the voltages on the three-pin connector coming from the motherboard: on my working Kronos there was a negative tension of about 9,6 volts on pin 2 (RX-data), while on the faulty Kronos 2 the tension was positive, about 10 volts... Something's wrong with the serial port interface on the mobo, I guess: I've bought some spare UART ICs (GD75232), I should receive them in about a week. I'll let keep you informed

Fixed! Smile
Replacing the UART did the trick. The Kronos boots again and everything works like a charm. It's been quite hard this time...
