Fixed. Don't use ASRock's copy of the chipset drives. Download directly from AMD.]]> Fri, 08 Nov 2019 00:42:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69758&title=ab350m-pro4-virtualization-problem#69758 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69757&title=ab350m-pro4-virtualization-problem#69757 Author: numeratrix

Disabling IOMMU didn't help.

My brother commissioned me to build this machine and he's not tech savvy. Virtualbox would be pointless. I want to be able to enable virtualization security features to help protect him.]]> Thu, 07 Nov 2019 22:46:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69757&title=ab350m-pro4-virtualization-problem#69757 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69681&title=ab350m-pro4-virtualization-problem#69681 Author: Kirurgs

Try disabling IOMMU, I think it's needed only for pcie device passthrough and try using virtalbox if You need just a virtual machine.]]> Wed, 06 Nov 2019 04:39:46 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69681&title=ab350m-pro4-virtualization-problem#69681 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69679&title=ab350m-pro4-virtualization-problem#69679 Author: numeratrix

ASRock says the only OS they support is Windows 10 for this board. They don't even do that though. I submitted a ticket weeks ago and they never responded. This is maddening b/c this is for a family member. I'm done with ASRock.]]> Wed, 06 Nov 2019 04:03:46 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69679&title=ab350m-pro4-virtualization-problem#69679 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69674&title=ab350m-pro4-virtualization-problem#69674 Author: Kirurgs

My son exactly this MB, but Ryzen 2400G. He virtalized a lot of OS, including macosx, BUT under Linux, w/ and w/o graphics card passthrough.
So from HW perspective it must work and issue is likely with Windows virtalization solution.]]> Wed, 06 Nov 2019 01:46:11 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69674&title=ab350m-pro4-virtualization-problem#69674 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69625&title=ab350m-pro4-virtualization-problem#69625 Author: numeratrix

I'll freely admit this kind of tinkering w/UEFI settings is new to me so thanks for your patience.

There seems to be multiple places you can change UMA Frame buffer Size.

I changed the UMA Frame buffer Size in:

Advanced\North Bridge Configuration

to 2G and it looks like that changed it in:

Advanced\AMD CBS\NBIO Common Options\GFX Configuration

also. I tried installing Windows Sandbox again and it stills fails to boot/complete the install. Please advise.               ]]> Mon, 04 Nov 2019 01:35:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69625&title=ab350m-pro4-virtualization-problem#69625 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69624&title=ab350m-pro4-virtualization-problem#69624 Author: numeratrix

Thanks for hinting at a new direction to explore. Much appreciated.

Increase the UMA frame buffer size from what? To what? It's set to auto by default..?

I never had problems like this when I was using the APU on a B450M Pro4 so I have to say it kinda seems like it is a BIOS issue. I know the industry has been going through AMD growing pains for some time now...I get it. It would be nice if ASRock actually responded to requests for support though. ]]> Mon, 04 Nov 2019 01:17:37 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69624&title=ab350m-pro4-virtualization-problem#69624 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69621&title=ab350m-pro4-virtualization-problem#69621 Author: Ray62

You maybe have to configure/increase the UMA frame buffer size in the bios too.

And this is not an Asrock issue, it is a configuration problem with the Ryzen APU.
Search for "ryzen 2200g virtualization" and you will see, that user with boards from other vendors have the same problem.]]> Mon, 04 Nov 2019 00:49:50 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69621&title=ab350m-pro4-virtualization-problem#69621 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69616&title=ab350m-pro4-virtualization-problem#69616 Author: numeratrix

Yes, it says SVM is on in UEFI. All the settings you mention are good. Virtualization shows on in Windows under Task Manager > Performance & all settings for Hyper-V show enable under systeminfo.exe.

No matter what I do I can't get anything that needs virtualization to install. ]]> Sun, 03 Nov 2019 22:31:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69616&title=ab350m-pro4-virtualization-problem#69616 https://forum.asrock.com/forum_posts.asp?TID=12801&PID=69607&title=ab350m-pro4-virtualization-problem#69607 Author: Ray62

Is SVM mode really on in the bios?
And i think you have to ensure that SMT is also enabled.

You maybe also have to enable
Advanced\North Bridge config\SR-IOV support
and
Advanced\AMD CBS\NBIO Commom Options\NB Config\IOMMU
