What does DCP watchdog violation mean?

Installed Windows with Bootcamp. It was successful, until this message came:

I do hope you got my file via e-mail.

Since then:

I told my problem for the manufacturer of the SSD and got this answer:

Thank you for getting back to me, I really appreciate it! Regrettably your model MacBook Air 6,1 is not compatible with Windows/BootCamp. We state it on our site of the SSD on the main product page:

Note: Not compatible with Apple Boot Camp when installed in the following hosts: MacBookPro11,1; MacBookAir6,1; MacBookAir6,2; iMac15,1 (Late 2014); iMac18,2; iMac18,3; iMac19,1; iMac19,2

If you have anymore questions, comments or concerns please reply to this email and I'll gladly assist you further!

Thank you for contacting OWC, have a great day!

Sincerely,

Cicely B.

As a test, take a look at VirtualBox (https://www.virtualbox.org) which is free. This will let you run Windows as a Virtual Machine. This should be better than Crossover, since Crossover is an emulator.

Also, can you provide some details of the particular program you want to use in Windows? Is it Graphics-intensive engineering software?

Sep 23, 2021 1:48 PM in response to Loner T

You assume right.

I have now tried VirtualBox and even Crossover. None of them are understandable to me. I have tried reading the manual, but that in itself was the most complicated.

I came so far as to the black window (=the other machine, I gather), in which was stated:

"FATAL: No bootable medium found. System halted."

Now is time to go to bed. Good night (or morning for you?)

These are screen shots to install Windows 10 using VirtualBox.

Create a new Virtual Machine. Click on Machine -> New.

Create a Virtual Hard Disk for the VM

Choose the hard disk type to be a VMDK

Make the disk dynamically allocatable

Choose the size of the disk as necessary. If you have enough disk space, choose about 128GB

Choose the boot disk.

Select the Windows ISO and choose Start.

and you should see this screen...

You can install Windows without activation for 30 days. I recommend you test it using the Virtual Machine, before you activate it. Moving Windows licenses can be a bit challenging, if you are unsure that your TitleVision software does not work as expected using a VM.

It probably would have, had I not already tested it by myself.

Now I followed you distinctly, but I wanted to erase my first Windows, even if it didn't-t work as it should. This was not done, I couldn't find out how.

So I did New Windows instead and was stopped on my product key. I have that nearby, so I didn't write it wrongly. Microsoft has probably registered my failed attempt; my produce key was alright then, I think.

I shall, but not now. Too much other things in the way. And sometimes (for instance tomorrow) I will go out in the wild and feel good for a while. Must go, actually, but that is another story.

Incidentally OWC have today asked me, if I have more to report.

I'll come again!

Wonderful. Enjoy your time with Mother Nature!

No worries! Post back, when you can.

Titlevision is open, but I seem to have forgotten much. That i expected.

More installation stuff, first. I have got four different program windows, or desktops, of which two are Windows 10. One of them totally black, the other with Windows and Titlevision. Now, my Windows doesn't feel the USB connections of this computer. I have tested with a exFAT USB. How do I make Windows reachable in both directions?

Good.

Do you want to post a screen shot and I can help identify these?

To support external device pass-through from the Mac to the VirtualBox VM, you will need to Install

Extension packs - https://www.virtualbox.org/manual/ch01.html#intro-installing
Double-click on the downloaded file, and you should see...

Click on Install
Check VirtualBox -> Preferences -> Extensions and you should see...

Now you can configure the connectivity using the steps in https://www.virtualbox.org/manual/ch01.html#intro-installing.

Back for a while.

You wanted to see the program windows or desktops. Sometimes there are four, now they are only two. I understand it is a way, when the user uses too many applications at the same time. Annoying, anyway.

I am presently working with a comeback on Titlevision, which I have in front of me. There's much I have forgotten. But I would like to get a much bigger Windows screen without distortions. I enclose a picture of what it looks like now, if the image insertion works for more than one picture.

Actually I am rather pleased with this result. I didn't find any automatic adaption to my screen but moved Windows here and there, until a circle was almost a circle. Up and down is full screen, apart from that I have a cinemascope screen, which Bootcamp gladly and fully used without distortions, even double screens. Now as it is, I am glad if I can work with it like this.

But I have to get my picture and film material somehow. Haven't managed to make my Windows see any USB sticks.

Sorry, correct is: DPC WATCHDOG VIOLATION.

Sep 4, 2021 3:18 AM in response to Giron-Kiruna__

Sorry about the serial number.

Sep 8, 2021 1:36 AM in response to Loner T

Never mind the double volumes, you explained that good enough.

My main concern is to get my Windows 10 usable in its own partition. I can't work with that program otherwise.

Sep 8, 2021 2:28 PM in response to Loner T

I am afraid I do not understand what diskutil list is, and the Terminal is too difficult for me. I can use it on direct ordering what to do, but myself…

Sorry!

Your USB folders should look very similar.
