Andreas Schnellbacher:
3.5 GB is much. Be happy with that.

Hyperthreading must be switched off for stability. See https://www.arcanoae.com/?s=hyperthreading. That's probably also mentioned somewhere in the ACPI docs.

Dave Yeo:
It's the Intel Hyper threading that is broken if the scheduler (all older OSes including OS/2) doesn't understand it, I believe the AMD does work but you can test.

Martin Iturbide:
Note: I split the topic.

Ivan: I updated the wiki page with your comments (https://www.os2world.com/wiki/index.php/MSI_A320M_Pro-VD_Plus). Please let me know if the audio works and if there is any trick on config.sys or unimix.

Regards

Hi Matt

Thanks Matt. I created a draft wiki page with the info you posted.

Can it please be possible for you to share here the PCI.exe and LSUSB report of this mainboard to include it on the OS2World wiki?  I have this article explaining how to use PCI.exe and LSUSB just in case.

Regards

Hi Martin,

Rather than fight with the multiple adapters that this board has (HD audio, hdmi audio and some sort of generic audio) I just use a C-Media Unitek Y247A USB audio adapter with a bluetooth transmitter attached to allow me to use headphones.

The first 3 attachments should be self explanatory, the last (mix.txt) is the output from unimix.
