My guess would have been:
Unused space must be formatted first, then you can resize

What is the size of the whole disk?

Blackbird / Re: The download location for factory default BOOTKERNFW

And there's AFAIK no performance advantage in doing this. If you have a second computer, you could access the Blackbird via ssh:
Code: [Select]
ssh root@blackbird -t -p2200
Then you could see the hostboot coming up like:
Code: [Select]

And you could also see Petitboot:

I'm not an expert on this topic (If one of my statements is wrong, please correct it ;)), but as far as I understand, the system crashes when the graphics card uses more than 4GiB (32bit). For example when you open a ton of Firefox windows. 40bit is 1TiB by the way, not 128GiB.

And even if a user would be affected by this bug, he would not notice it.

Here is a list of working PCIe to M.2 Adapters.
AFAIK, there is no PCIe4 card out there. And IIRC, the Asus card is only partially working (at best), because of the missing PCIe switch. A PCIe switch is needed to get all NVMe slots working.

There is no BOOTKERNFW bundled. Because the systems doesn't come with any OS. You have to download your desired Firmware yourself.
You have to follow this instructions.

Advantage in doing this is to get a screen on Petitboot. Drawback, you have to repeat the procedure after each Blackbird-Firmware update. Fortunately, there is rarely a firmware update.

Have you tried to disconnect the BD-drive, whether the problem disappears or persists?

Is there any way to enable a suspend-mode in Fedora? Because, when I press the suspend button I get a black screen. Power consumption drops from 54W to 51W. My guess, only the AST is suspended? Then I couldn't wake up the computer again.

I have also read:
Unlike the previous architecture of the POWER8 processor, POWER9 processor only supports one instruction to enter idle state. POWER ISA (Instruction Set Architecture) has been revised to remove legacy idle state instructions (nap, sleep, winkle). A new instruction, 'stop', has been added for this purpose to the ISA.

WARNING: Due to the heatsink design, an external air duct must be utilized if using this heatsink outside of a high airflow 2U server chassis, for example in a desktop system. This heatsink is not designed for passive cooling without an external fan and, if required by a non-2U chassis, an external air duct.

2U Heatsink

I just found this, don't know if it works.

About the Secure Desktop, I think there are options as hell. You only have to ask Raptor ;)
I'm located in Germany. In this case the customs are equal to VAT (19%).

And regarding Vikings, the more people show interest, the faster things will change. At the latest when Raptor brings out the POWER10 or a notebook I will ask Vikings about it, too. My delivery took two weeks.

You don't need to update the Firmware. If you want to update, it's pretty easy. Even as a non-programmer.

What is the problem with the installer of Debian? I installed several distributions. Almost all worked without a problem. Debain, too.

About glamour etc.: You only have to create a file and C&P a few chars. That's it.

In the meantime, it would be good to collect some Linux experience before buying a BB.

Linux is different from Windows or Mac. You cannot install Linux and expect a MacOS. Linux will remain Linux.
If you are looking for support, IRC is very helpful. There are mostly developers there, but everyone is very helpful.
But what is really basic is the will to educate yourself and the ability to use Google search properly.
If this will is not brought along, then it will be very difficult. Because as I said, Linux will never become MacOS.
I had MacOS before my BB and the beginning was really hard.

But maybe you're right and some things are changed in two years. I have no objection ;)

I don't have that system by my own, but you could see it on the picture: Phoronix

I would call it "enhanced cooling system" instead of different.

I think it's only called Blackbird II, because of the different cooling system.

Just out of curiosity, do you also have a MPC86xx-RDB or T4240-RDB from Freescale? If so, maybe you can do some benchmarks with the Phoronix Test Suite? :)

Blackbird / Re: Heatsink dual fan configuration
« on: January 25, 2020, 05:55:34 pm »

I thought shawnanastasio / dormito are the same person. Sorry about that.

In the next couple days I will do some small modifications on my setup. Also I will put in an ASSMANN AK-610300-003-E. Then I have a serial connection. What just comes to my mind, wouldn't it be better to buy another chip and program bangBMC on it? Then you can easily change the chips if needed. I have a Bus Pirate, too.

Could you please post a picture of your 2U heat sink setup?
Never seen one. :-[

At the end, it's a 3U HSF, little bit smaller and without fan.
