First of all, thanks for all the info. Some interest food for thought here.

That should not be a problem: there are ps/2 splitter cables for this. In fact mouse and keyboard are connected to different pins on the ps/2 connector.

I was not aware that those kind of splitters existed. May have to give that a try.

My setup is a 4 port Tcnewcl 4k KVM switch which takes USB 2.0 keyboard and trackball as well as my 28inch 1920x1200 HDMI monitor. The main computer has a MSI A320M Pro-VD Plus motherboard, another possibility is the ASRock AB350M Pro4 - it has 2 PS/2 ports which you want.
BTW I think you should be thinking about upgrading your KVM switch to enable you to have a much wider choice of motherboards.

Well, that present a bigger issue. I currently have 7 systems running into my KVM. I moved from a set of Linked 4 Port OMNI's I switched to a 16 Port TrendNet TK-1601A about 6 years ago. I tried several that had USB instead of PS/2 ports, but could not get all my systems, (Mix of Windows 7, Windows XP, OS/2 and ArcaNoae) all working with the USB Version, so I went back to the PS/2 port one. Converting all the systems is not a task I'm willing to undertake. I've had good luck going from USB to PS/2 with adapters, but less luck going the other way.

Video is not an issue. I've got a mixture of DVI, VGA and HDMI outputs on my systems, I just use the appropriate adapter to convert to the VGA that my switch uses.

Any Lenovo M series desktop computer in the last 15 years would work with your requirements -- I've tried pretty much all of them.
You can go with the hobbyist market -- It's more of a hobby than a rational decision. I know several skilled hobbyists inhabit OS/2 World. If building your own computer brings joy, go for it.
You can buy refurbished computers from the many of the major electronics retail websites now.

I have not bought a commercial desktop computer in over 25 years. I've always built them from the pieces. That way I don't get any of those nasty windows kludges that the various vendors have put into there systems over the years.

Interesting this came up - I just got a new Gigabyte B760M DS3H MoBo to use with an i5-12600K processor. to replace my old B365M w/i3-8100 system. Was going to dual boot Windows 11 and ArcaOS 5.1 and was able to install everything and it 'works', but ArcaOS only sees 860MB of memory even though 16GB is installed. No amount of BIOS tweaking would change that, so I decided to do what I hoped would never have to be done, and that is install VirtualBox in Windows and run ArcaOS from there.
Installed ArcaOS 5.1 in VirtualBox and got it working. Normally, I would then zip up my previous install from the old computer, and unzip over the new install on the new computer, boot it, and change whatever drivers needed changing (usually just the NIC). This also 'worked' except I now only have one choice of screen resolution, and that is 640x480x16, even though the original install had more. Tried re-installing the VirtualBox additions from the ArcaOS iso, but no help. Also tried running the ArcaOS install again, but no change.
I am assuming some file was changed needed for VirtualBox when I unzipped my previous install over the new VirtualBox install - anyone know what file that might be? Or how to get back the screen resolutions installed originally?
Regards,
EDIT: added testlog booted to new hardware.

Using VirtualBox I can set it up to 1920x1080 running a command form the Virtual Box host on Windows to change the VM screen resolution.
Here it is the procedure I used, maybe you can give it a try.

Thanks for the report. I created a wiki page for it: https://www.os2world.com/wiki/index.php?title=Gigabyte_B760M_DS3H
Just a little request:
1) Can you updated the "pcidevs.txt" file to see if some of the "unknown" devices get recognized ?
2) Is the Network and Audio working?
Regards
David McKenna:
Hi Martin,
I did follow that procedure after the initial install and it worked. After unzipping my previous ArcaOS install, it did not. I'm pretty sure there is a file or setting in a file that got overwritten by the unzip. Just have to figure out what it is. I'll probably install another ArcaOS virtual machine and start studying the difference between the fresh install and my unzipped previous one.
Got the absolute latest pci-ids file and re-ran testlog - attached. Still some unknown devices though. Also noticed testlog complains about hyperthreading, but it is turned off in BIOS - strange..
Regards,
PS - almost forgot - sound works, but the NIC is not recognized (a Realtek 2.5GB). I installed an Intel 1GB PCIe NIC just for this situation.
