ASRock B550M-HDV

[Eugene Tucker]

I just successfully installed Arca OS 5.1 on this motherboard with EFI enabled. It seems to install a little slower in this mode but it runs just as well when installed as my CSM computer. Now we have another alternative.

Hello Eugene.

I have this report from Matt Walsh from 2020.
-- https://www.os2world.com/wiki/index.php?title=ASRock_B450M-HDV_R4.0

It is the same Motherboard, right?

I never got the PCI.exe report to put the HardwareID on the table. If you can provide it to me I can include those too.

Regards

Martin, Sorry But it was the  wrong model I posted. The real model it was the ASRock B550M-HDV.

Ok, You already reported it:

If you can share the pci report (or the testlog) please post it over.

What is working? Sound, ethernet?

Regards

It was working before under CSM This is under UEFI.

Run a sysbench

The performance difference between CSM and UEFI mode should be just about 0.  UEFI code is mostly active when ArcaOS loads. Once the OS is loaded the impact of the UEFI loader is well under 1% is not lower.
GPT filter driver will have about a max 15% impact.

Measure it then you know what you are dealing with.
