This is getting painful 
 
Tried to update the bios in windows.  After the second prompt (in yellow), windows locked up for 30 minutes, so I called technical support.  They suggested a reset, and if the MB wasn't bricked, try it from safe mode.
 
Booted into safe mode and tried again.  I got a command window trying to get Admin privileges, but after 20 minutes I still didn't get a UAC popup.
 
Fine, screw it, let's just do this from DOS.  Created at DOS usb stick, which I can't get the bios to let me boot from.
 
Any help is appreciated.
 

It's all good now.  It turns out that you need to disable UAC in Windows for the update to work properly.  The tech that I finally got bumped up to figured it out in ten seconds.
 

Hello,
 
I recently put together an SR-X build (two Xeon 2670's) with BIOS v1.03. I have turned on Intel Virtualization which enables VT-x. Should this also enabled VT-d or is there another setting for that?  These processors do support VT-d and VT-x.
 
Thanks!

Hello,
 
I have found the root cause of this issue. 
 
With BIOS 0.11 under Chipset > IOH Configuration > I find Intel VT for Directed I/O Configuration and inside I can enable VT-d. 
 
With BIOS 1.03 under Advanced > IOH Configuration > I do not find Intel VT for Directed I/O Configuration. I do not see Intel VT for Directed I/O Configuration anywhere within this BIOS.
 
I specifically need this BIOS as it adds GTX980 support however, I need to be able to enable VT-d as well as this allows GPU pass through to VMs.
 
I know this works with this current hardware as I am able to pass through a GTX560 on the same hardware just not the GTX980 because the older BIOS does not support it. 
 
Thanks!
 

Hey ogman, 
 
Thank you for the reply. 
 
I did install the custom bios that you have linked however Intel VT for Directed I/O Configuration is not listed under IOH settings or anywhere else I can see. 
 
Is this something you can look further into perhaps as EVGA remains silent? 
 
Thanks! 
 

Hello,
 
The option under CPU configuration for Intel Virtualization Technology is there and enabled and does enable VT-x.
 
I need VT-d to be enabled as VT-d allows for GPU pass through to VMs.
 
This option is available in BIOS 0.11 however, 0.11 does not support my GTX980.
 
Thanks! 

Hey, 
 
I need to post 4 times before I can reply to PM. Trying now. 

3 out 4.

So as I said above I only bumped to be able to reply to a PM because for whatever reason EVGA needs 11 posts to reply to PMs. 
 
Never the less this issue is still not resolved. Maybe you XrayMan can get a hold of one of these EVGA techs and have them actually read and understand my issue? 
 
 

The current BIOS Version is:
Driver Version: 1.04 Release Date: 4/16/2018
Driver File: Download [http://cdn.evga.com/bios/SRX/W888_flashtool_104.zip]
This BIOS is intended to update the CPU microcode to increase security related to the reported Spectre vulnerability for processors used on EVGA SR-X Motherboards. 
This microcode update is expected to be used in conjunction with related patches from your Operating System or VMM to ensure complete protection from reported vulnerabilities.
 
In the Windows System Information it is reported as:
American Megatrends Inc. 4.6.5, 04/09/2018
 
So at least, if you think Spectre&Co might be a risk for your system, you should update to the latest version.
No screwing required, just unzip the package, run UPDATE.bat and re-adjust the BIOS settings.
