Modern Motherboards - Whats working
ivan:
Just an observation. I notice that most people seem to follow the win idea and cram everything into the one partition and then have problems getting everything working again.
My setup has 9 partitions, a small one (2GB) only for the operating system (it could be smaller but I can't be bothered to change it), then I have one for tools another for programs, another for work and yet another for home as well as a few odd ones for storage. In fact apart from new operation systems (OS/2, OS/2 warp and now ArcaOS the other partitions remain untouched except for the odd update as necessary.
My reasoning comes from when I was guiding a couple of companies that were setting up with OS/2 and I see no reason to change it. I will add that I now have a Linux mint based computer at the side of my desk so I can use a newer version of firefox to download or screen grab what I want, and network it to my OS/2 unit for processing.
Doug Bissett:
I have been skipping through this, but thought I would add a few comments. Unfortunately, I am not at home, so most of this is from my failing memory.
I, recently, got an Asus x570 Tuff Gaming motherboard, with 6 core (12 threads, for windows) AMD 5600G (?) processor. Put 16 GB of memory in it, with a 1 TB Crucial NVME stick for disk. After I looked through the UEFI BIOS, and turned off a number of things, it is working well. Over 3GB memory available to OS/2. Sound works (UNIAUD needs /A:1). The 2.5 Gbps Realtek NIC works (with Multimac MMRE, but I can't say if it runs that fast since I don't have another machine with 2.5 Gbps). Video is HDMI only (works well, with a 1920x1080 screen, and Panorama).
Overall, I am very pleased with it.
David McKenna:
Figured out the problem with unzipping a previous install over a VirtualBox install - the file 'C:\OS2\svgadata.pmi' must be deleted after unzipping. It is apparently used by Panorama and messes up VirtualBox if it is present. The VirtualBox additions install does not delete it. Now I can run a full screen OS/2 session in VirtualBox at native resolution.

I ever thought this file is used for SNAP only. But maybe all gradd based drivers use is? SNAP manual deinstallation instruction mention that deleting this file is needed.

Eric,
I am running AOS 5.1 on a MSI PROB550-VC motherboard, Ryzen 5 5600x, with a Radeon X600 graphics card, SNAP . Mem says 16,355 MB (3,567 MB accessible to system)
The motherboard has one combo type keyboard/mouse PS/2 port. You can plug in a mouse, or a keyboard, but not both, even when using a splitter or y cable. I tried. And after trying the y cable and failing I found other people posting on the net with the same issue with other motherboards. Apparently to use both a keyboard and mouse at the same time (via a y cable) the motherboard has to be built to to accommodate it.
You said you wanted 8 cores. Remember - more cores equals more cost, both in terms of watts, cooling and money. My system at the desktop consumes 62 watts. It consumes 4 watts when not running - unless I turn off the power supply. I have seen a maximum of 130 watts at boot up and when watching a movie on VLC, Compiling small (3.5 mb applications) gets it to 87 watts.
The motherboard/processor/SSD combination works well in OS/2 - with the following conditions/issues.
I believe you can mix GPT and MBR disks in the same machine, but there are considerations when booting.
The alternatives for a 'boot manager" for booting into different disks/partitions are: 1) the boot menu from the bios, 2) the AOS 5.1 GPT boot manager, 3) Airboot. The bios boot menu will boot to either MBR or GPT disks. The AOS GPT boot manager will only boot GPT disks. Airboot will only boot MBR disks. On this machine Airboot does not work with a USB attached keyboard - you have to use a PS/2 attached keyboard. On my Thinkpad T530 with AOS 5.1 Airboot works fine.
On this machine some Windows applications lock up the machine when running in Win-OS/2 seamless mode. They appear to run fine in Win-OS/2 full screen.
Once OS/2 boots up it is fast. However this machine takes longer to boot than my Thinkpad T530.
Finally - I would strongly encourage you to check out Neil's stuff (Blondeguy.com) when going through a make-buy decision. If he has what you need it might save you a considerable about of time in specifying, buying, assembling and troubleshooting a new machine. Plus he list the watts used by various machines you can get an idea of the trade off between cores and electricity usage.
