OS/2, eCS & ArcaOS - Technical > Hardware

To take the bun for the last time: ArcaOS and Lenovo Thinkpad Z13 Gen 2

<< < (2/10) > >>

Sigurd Fastenrath:
It is up and running!  ;) ;D

In BIOS I had to:

- Disable SecureBoot
- Enable Pluton and TSM 2.0

Then the rEFInd Manager started and I was able to load Windows 11 Pro and start it with Fingerprint and as well start ArcaOS.

ArcaOS sees 1.4 GB of RAM while there ar 57GB for the RAM Disk available.

I will test some more things later, like getting sound and other things to work.

ArcaOS runs really fluent for now, please note the temperature and Battery/Power widget in the xcenter.

Have a  nice Sunday!!

Sigurd Fastenrath:
So, after some time of investigating, I was able to customize the rEFInd Manager the way I like it. I collected some icons for this.

rEFInd outclasses the ArcaOS EFI Bootmenue by far, especially when it comes to an aspect ratio of 2.880X1.800 Pixel. ArcaOS EFI Manager is very very very small then.

Despite the Background of rEFInd and an additional Linux Installation on the Device I am almost through.

This is the lowest amount of RAM I have seen yet. Every generation has less than the one before it. It would be interesting how Dooble will function on this system.

I tested a Lenovo X13 laptop with a Ryzen 5 Pro 6650U CPU and got 1840.50 MiB

Sigurd, as I follow this thread, it's great news that you got both Win11 and AOS up and running on this Thinkpad. If I'm following correctly, it means you can dual-boot (multiboot) into one OS or the other.

One remaining task seems to be preserving all this effort, as in, imaging both OS's plus the EFI stuff, to the point where you can resurrect the entire machine from scratch, and get it right back to where this known-good state.

I also assume that AOS can see 1.4GB of "free" RAM, as this seems to be a 64GB ram system. This means you'll have one OS/2 running at any time, and you'll still be somewhat RAM-bound at times, depending on what you're doing. Possibly, you'll still be fiddling with hardware issues here and there, under OS/2. If you need something under Windows, you'll be rebooting into that OS, and losing access to OS/2 temporarily.

In the meantime, there are plenty of powerful hardware resources left over on your machine needing exploitation, and perhaps not just as a RAM drive?

Might I suggest AToF'ing (ArcaOS - Thrusters on Full) this system? All the docs are in the "virtualization" forum of OS2World.com. These docs have received lots of "views", but not much in the way of feedback. AToF docs are at:

  os2world.com/forum/index.php/board,24.0.html

From where you are right now, I'd suggest this quick test, which shouldn't risk any changes to your existing build in which you've invested so much time:

1. boot to Win11, install Virtualbox, and then install AOS in a VM, and see how it works for you, including how much free RAM is available inside that VM. Note that both OS's are running at once, which is powerful magic, as you can switch between them with a mouse click.

2. now install another AOS in a VM (for test purposes, just reuse your AOS license), and perhaps even another. Each has 4GB of RAM to play with, and you are no longer bound to one AOS. In the meantime, each is accessing the resources available to the Win11 OS above it, meaning wireless network access, etc., and everything is running at once, with no multi-booting.

This test doesn't really change anything on your current Thinkpad build, as you can throw the test parts back out again (remove Virtualbox and the VM's). But, it does let you, or anyone else with a similar laptop setup, see the power of running everything at once, with virtualization and multiple VM's. You'll still have more resources for other VM's, for Linux, for development, or whatever.

I don't have Thinkpads myself, and am not tied in to the "experience of ArcaOS on any given model of Thinkpad", but I've run a similar test on my Dell laptops, and others, and it works well. It would be helpful if you ran the same (reasonably quick) test, and reported your experiences back to the forums. No other part of AToF needs to be done, just this part of Virtualbox and VM's.

You'll be in a unique position where you can test things under AToF (ArcaOS in a VM), and/or test things under a boot straight into ArcaOS via rEFInd, and compare/contrast both experiences.

Plenty of folks might have all kinds of issues with running OS's in VM's (particularly OS/2), and until that gets exposed by folks running more tests, we don't really know if AToF is all that helpful, especially to the ArcaOS/Thinkpad set of folks.

Obviously, you can disregard my whole post and continue running one OS at a time, out of your current two OS's under the EFI/rEFInd setup. Again, it's really great that you got to this point! But, if you can run the test, it would help plenty of others who might be considering AToF but not wanting to take the risk until others have tried it and reported back ...

I might be able to add to AToF the ability, as noted by others, of running ArcaOS in a VM or easily booting directly into ArcaOS, if any issues need comparison to sort out.

A long post, but your new machine should rip right through it in seconds! Good luck with your new build!

Martin Iturbide:
Hello Sigurd.

Is it possible for you to post the testlog report of your machine so I can add the details in the OS2World wiki? (please remove the serial number for privacy)

Please let me know if Audio works.  What else works and don't work?

I'm checking the specs and it says "2x USB4 40Gbps (support data transfer, Power Delivery 3.0 and DisplayPort™ 1.4a)". I don't see a video output port on the pictures, I' not sure if those USB-C to HDMI adapters will work.

Regards
