- BCU to Enable VTx and VTd

So I have been trying to enable Virtualization using the BIOS Configuration Utility on a series of Z210, Z220 and Z230 workstations. So far I have not had much success with enabling these entries, but for whatever reason it appears you can disable them using the BCU.
The specific entries that I am trying to enable are:
- Virtualization Technology (VTx)
- Virtualization Technology Directed I/O (VTd)
- Intel TXT(LT) Support
I am using BCU version 3.2.3.1 and a password configuration file created using HPQ Password Utility 1.1.12.1.
Systems are running a Windows 7 x64 personalized image (Tried on an HP stock image without success)
The command I am running is:
BiosConfigUtility64.exe /Advanced /SET:"Z230_BIOS_V.txt" /CurSetupPasswordFile:"Z230BIOSPW.bin"
Bios configuration file contains the following:
English ; ; Settings file originally created by BIOS Config Utility ; Version:3.2.3.1 ; Date:2015.01.26 ; Virtualization Technology (VTx) Disable *Enable Virtualization Technology Directed I/O (VTd) Disable *Enable Intel TXT(LT) Support Disable *Enable
I get the following information upon running the command (in this case showing that only one of the values needed updating):
<BIOSCONFIG Version="3.2.3.1" Computername="NameRemoved" Date="2015/01/26" Time="12:12:52" UTC="-6" > <SETTING changeStatus="pass" name="Virtualization Technology (VTx)" reason="" returnCode="0"> <OLDVALUE><![CDATA[Disable]]></OLDVALUE> <NEWVALUE><![CDATA[Enable]]></NEWVALUE> </SETTING> <SUCCESS msg="Successfully set BIOS configuration." /> <Information msg="BCU return value" real="0" translated="0" /> </BIOSCONFIG>
I then shutdown the computer and wait ~30 seconds before turning it back on. When I then export the configuration using the BCU, I get the following showing that the values have not been updated.

Anyone have any ideas or experience with this?

If you set these values using F10 setup, save and reboot - does BIOS save them after a reboot ?
Based upon the results you posted, BIOS reported to BCU the values were set successfully.
I know from discussions with the development team, BCU simply reports what BIOS told BCU.
Can you set/change other BIOS values with BCU that are saved after reboot?
I have not worked with the VTx/VTd settings before so I wonder if there are other pre-requisites.
example - TPM requires a BIOS password be set, but it appears you already have that so I can only suggest trying the items above.
Perhaps there is someone else that has experience with VTx/VTd specifically that will see your post.
Thanks,
Richard

Richard thanks for your reply.
Yes, the values for the VTx and VTd entries can be updated and saved by entering the BIOS, updating the values and then saving the changes.
Other settings can be changed without an issue. The values for VTx/VTd can even be updated to "Disabled" using the BCU and the change stays after reboot. The issue only occurs when trying to enable these settings.
I set the password just in case it was a requirement and am wondering the same thing, but documentation on these settings are lacking. The only options I can see are that their are other prerequisits, this behavior is by design, or there is a bug in the Software. I am hoping for the first one.

Ok so I think that I may have stumbled upon the answer. I switched to yet another Z230 system and attempted to push down the configuration to it. Ended up with the same result when looking at the output from the BCU.
I checked out the settings in the BIOS and found that the lines for setting VTx amd VTd were greyed out, and the entry for LT support was missing while the BCU output showed it as enabled. I disabled LT using the BCU and power cycled the system. The VTx and VTd were no longer greyed out in BIOS. Booted into Windows and ran the configuration script with VTx Enabled, VTd Enabled, LT Disabled, restarted and it worked.
Checked the BIOS on the original systems and found that while LT was enabled it did not grey out VTx and VTd. Reflashed the BIOS on them and then tested enabling LT with the BCU which then greyed out VTx and VTd. So it appears that this is a dependacy and that there was something wrong with the BIOS on the first couple of systems.
So best I can tell if you want to enable VTx and VTd using the BCU you need the following:
- Set password on the BIOS
- Disable "Intel TXT(LT) Support" using the BCU
- Reboot
- Enable "Virtualization Technology Directed I/O (VTd)" and "Virtualization Technology (VTx)" using the BCU
