Hello Victor,

>> Yes, DMAR table might not exist if vt-d is disabled in BIOS.

On our NUC, we have VT-d enabled in VisualBIOS but, there is NO option for IPU.

How do we get DMAR tables in this case ?

Thanks,

Rajagopal

Hello Rajagopal,

I'm not an expert but just a user of ACRN; we've had a similar issue on one of our boards. To enable DMAR table in ACPI, ensure in BIOS settings that IPU is disabled, and VT-d instructions are enabled. If you still have the same error, you'll have to ask your BIOS provider to add the DMAR table.

Hello Victor,

We are also trying to run ACRN on NUC5CPYH.

PFA the following ...

1. screenshot of the error while running board_parser.py
2. o/p of cat /proc/cpuinfo
3. screenshot of VisualBios details, currently configured to UEFI-only mode

Can you please help us get past this ?

Thanks,

Rajagopal
