[Xen-users] VT-D On An Asus P5E-VM DO
Hello,
I've been trying to get VT-D working on my Xen installation for the last few days. I've got an Asus P5E-VM DO motherboard, which is explicitly listed on the VTdHowTo page of the wiki as supporting VT-d, and a Core 2 Quad CPU. I'm using Debian as my dom0 OS, and I've built Xen 3.4.1 from source.
The error I'm getting now is: (XEN) [VT-D]dmar.c:388: RMRR error: base_addr d0000000 end_address cfffffff (XEN) Failed to parse ACPI DMAR. Disabling VT-d.
A little googling suggests this is a BIOS issue. I recently upgraded my BIOS to the latest version in order to see if that would resolve a different problem (it didn't), so now I'm wondering if VT-D would be working on an older BIOS revision.
Anyone with an Asus P5E-VM DO and VT-D working care to tell me which revision their BIOS is?
Cheers, Mike
