I virtualized my very old running OS/2 computer about year
or two ago. It is running under VMWare now, and it is very
stable. No phone lines, no special hardware, so it was
quite painless conversion. Might be possible to run it in a
VPS too, but I haven't tried.

I'm running mine using ArcaOS PE 5.0.3 on an older but still quite powerful
for my needs Dell Optiplex GX620 (3.2 ghz P4 HT, 3GB RAM, 1TB of storage). Works just fine for me. When I get a chance, I'm going to see if I can get ArcaOS to run on my Dell PowerEdge R710 (dual Xeon 2.6ghz processors for 16 cores, 48GB RAM, 4TB of storage).

Why? Because I can. :D

I never got ArcaOS or ECS to virtualize properly under VMWare, which is why I use VirtualBox to handle that.

From what I have been told by people who are smarter than I am, evidently
only VirtualBox has the support for some of the archaic low-level system
calls that OS/2 and its descendants use when working with ring 0 stuff upon boot.

I've had no problems with OS/2, eCS, or ArcaOS virtualizing under VB.

Hi Sean!

01 Mar 2020 15:47, from Sean Dennis -> Tommi Koivula:

The worst architecture from an energy burning perspective.
Extremely huge pipeline that burns electricity like no tomorrow, and artificially increases clockspeed while at the same time DECREASES performance. Every pipeline stall needs to flush all the stages.
And there is a huge number in stages on the P4. (there is a pipeline stage in the P4 that does NOTHING but drive the signals on the chip ... no actual work is done)
In the architecture afterwards they HALVED the stages ... hmmm wonder why they did that :)))

BTW that architecture was much more energy efficient and performant.
But it had lower clockspeeds.

I have a WinXP, IBM Thinkcenter MTM8143 tower/P4 530 3GHz/2.5GB 75GB HDD

Does it fall into the "worst architecture" class too?

It is/was poised to be an experimental Linux Mint pc someday. Or I
might send it to the landfill because I don't like the sound of the
fan running. The XP in this particular pc seems to be accessing the
HDD every second and the sound is very noticeable. The live boots of
Linux don't do that; hence, the desire to turn it into a linux box

It has the fairly modern SATA hd connectors and can support 2 hdds.

replace the fan... depending on which one it is, it could be a five minute job and may cost less than $10US...

Yes.
Anything Pentium 4 (P4) falls in that category.
It started bad with a 20 stage pipeline (with wrong optimization emphasis).
It then went to CATASTROPHIC with a 31 pipelinestages at a later point in time.

It is the abomination Intel called the Netburst architecture.

BTW. the previous Pentium Pro (2/3) and later Core Architectures are pretty good!

It worth looking into, I guess. It's the one that is surrounding the CPU
and the heatsinks. It's a huge funnel contraption.

I don't think there were "better" alternatives for a newer pc at that
time. I got mine through the re-certified offerings from ibm.com store. Granted, price was the driving factor.

probably a standard muffin fan hiding in there... i had a HP or Compaq machine here that had a tube from a set of holes in the side of the case to the top of the CPU fan... when i used the case for a different MB, i simply removed the tube... but yeah, there's probably a bog standard muffin fan hiding in there...
