HP ProDesk 600 G1 SFF, no VTd option in BIOS, thus can't enable?????

[userACdc]

There is no VTd option at all in BIOS?

Can't find anywhere to enable this option.

Help please?

Thanks

VTd is a Bios option under the "security" section 

please read the HP document linked below

https://support.hp.com/us-en/document/c04272032

• Data Execution Prevention (enable/disable) - Helps prevent operating system security breaches. Default is enabled.
• Virtualization Technology (VTx) (enable/disable) - Controls the virtualization features of the processor. Changing this setting requires turning the computer off and then back on. Default is disabled.
• Virtualization Technology Directed I/O (VTd) (enable/disable) - Controls virtualization DMA remapping features of the chipset. Changing this setting requires turning the computer off and then back on. Default is disabled.
• Button Retask Password Protection (enable/disable) - Controls whether or not the Setup password must be provided to WMI methods used to re-task the function of the side panel buttons.

Hi DGroves,

Thanks for your reply but I'm unable to find the VTd option?

Even the BIOS version is current.

Please see the screenshot below.

Look at the link DGroves has sent you: https://support.hp.com/us-en/document/c04272032

In the left-hand column it says: System Security (these options are hardware dependent) 

It turns out that not all Intel CPU's are capable of virtualization.

Read Intel's publication:

Does My Processor Support Intel® Virtualization Technology?

Hi Joselso,

Thanks for explaining, I've checked the CPU with Intel's website, it is i5-4670 https://ark.intel.com/content/www/us/en/ark/products/75047/intel-core-i5-4670-processor-6m-cache-up-...

VT-x and VT-d are listed as supported, any ideas?

Any help would be appreciated!

Thanks!

I have now looked at my old hand-written records from December 2012 - that was when I prepared my HP Z820 BIOS settings to be able to install virtual Windows XP-Mode over my Windows 7 Professional:

As long as VTx is disabled as default, the BIOS does not show VT-d options at all and VT-d remains disabled as default;

however, once you enable VTx (as shown in your post) - immediately there should appear additional settings including VT-d for you to be able to enable it.

For some reason I cannot guess, VT-d remains unseen in your list of BIOS System Security settings even though VTx is enabled.

You may try to exit BIOS while VTx is enabled (keep changes and exit), and restart and reenter F10 and see if now the missing VT-d appears as it should, and then enable it, too.

Another possibility (that I use) is to install HP Performance Advisor

https://www8.hp.com/us/en/workstations/performance-advisor.html

in Windows Operating System (in my case, in Windows 7, it is OK, but I am not sure if Windows 10 is also suitable to accommodate this application, for there have been complaints in this forum on this matter) and within this application you can read and modify BIOS settings (requires Administrator permissions for full accessibility). Thus you may find that the 'unseen' VT-d setting is available after all, and you may be able to enable it that way.

you may also have to enable/disable the Intel "AMT" if your bios supports this option

last, i would try a factory cmos reset back to factory defaults

Thanks for your replies.

I've shorting CMOS, tried disable and enable vtx, still no luck.

Tried Advisor, still not working.

Could it be possible the board does not support vtd?

It seems the Board is 18E7?

Any ideas?

Thanks!

I have a 4590t and I too can only enable vtx and have no bios option for vtd.

I also tried advisor and even though it shows vtd nothing happens when I select enable.  it just stays at disabled.  

the bios is current at l04 v02.33

thoughts?

UserACdc,

Any luck getting vtd to work?

I'm looking at buying the same pc, but I need to know if vtd will work first.

Are you running the latest bios already? 02.78 Rev.A

Thanks
