[REQUEST] MSI X58 Pro E and VT-d

[colokarl]

Hi Folks,

first Post here.

i have a MSI X58 Pro E Motherboard running a Xeon E5649.

Most (if not all) X58 BIOS have a faulty VT-d Function (something related to DMAR Table), see the X58 Section in the following Link.

https://wiki.xen.org/wiki/VTd_HowTo

This is due to an incorrect BIOS handling VT-d.

As Asus for example released a BIOS which fixes that VT-d error, but MSI did not, i wanted to ask you guys if you could have a look at the current MSI Bios and transfer the fix, that ASUS did to the MSI Bios.

The MSI BIOS is here:

The fixed Asus Bios Changelog:

https://www.asus.com/de/Motherboards/SABERTOOTH_X58/HelpDesk_BIOS/ => see description

Code:

Sabertooth X58 BIOS 1402
Improve VT-d compatibility issue

The BIOS itself is this https://dlcdnets.asus.com/pub/ASUS/mb/LG...S-1402.zip

I would really appreciate it if an expert could have a look at this and if its not to much work, edit the BIOS to make the Board VT-d usable.

I just bought that Board, built a very nice esxi box including a GRID K2 with it just to find out, that VT-d is kapoot on that BIOS, which renders the new box kind of useless for me.

Any Help is appreciated - I gladly would donate some $ to whoever gets it done.

Have a nice day

So, to add a lil bit more how that turns out on a linux host:

Jun 27 13:03:40 aa systemd[1]: Started Tell Plymouth To Write Out Runtime Data.
Jun 27 13:03:40 aa kernel: [    0.000000] APIC: Switch to symmetric I/O mode setup
Jun 27 13:03:40 aa kernel: [    0.000000] DMAR-IR: This system BIOS has enabled interrupt remapping
Jun 27 13:03:40 aa kernel: [    0.000000] on a chipset that contains an erratum making that
Jun 27 13:03:40 aa kernel: [    0.000000] feature unstable.  To maintain system stability
Jun 27 13:03:40 aa kernel: [    0.000000] interrupt remapping is being disabled.  Please
Jun 27 13:03:40 aa systemd[1]: Started QEMU KVM preparation - module, ksm, hugepages.

Now i tried almost any kernel parameter to see, if it can be fixed from a kernel matter. No luck until now.

If anything, could someone at least point me in the right direction as how to do this myself ?

I am willing to donate either to this site or the expert who can provide an updated bios with this DMAR fix as i really want to use this box with VT-d features.

Any help is appreciated

Hi ... I believe nobody can do this...

Take a look on this file from Intel:

https://web.archive.org/web/201207280053...update.pdf

In this document you have many issues listed related to VT-d (See page 8 and 9 for more details):
Issue numbers: 45, 46, 47, 48, 49, 50, 51, 53, 60, 62, 67, 68 and 69

In that table they show which revisions are aftected (Page 10 for more details):
B2 = rev 12
B3 = rev 13
C2 = rev 22

After getting your revision and knowing what issues still remain you could verify each one on the remain pages and you will find that some of them has NO WORKAROUND, other is possible to PATCH the MODULE of the BIOS that control the chipset.

To determine your revision easly command:
lspci -n | grep "8086:3405"
