BIOS enable SLAT (EPT) no possible

Hi,

 

I have dell T110 (bios 1.6.4) with intel G6950  run hyper-v 2008 r2 SP1 and some VM 32bit and 64bit all work fine. I have upgrade my hardware with video card (asus g210 silent 1GB) my target is enable hyper-v RemoteFX in windows 7 enterpride VM. I have discovered I can't enable RemoteFX because there is not enable EDP in the bios, I have used utility "coreinfo.exe" http://technet.microsoft.com/en-us/sysinternals/cc835722.aspx 

Now  processor  setting in the bios are:

Virtualization technology                            enable

Execute Disable                                         enable

C States                                                     enable

and if I use microsoft utility coreinfo.exe

coreinfo -v:

HYPERVISOR      *       Hypervisor is present
VMX                      -       Supports Intel hardware-assisted virtualization
EPT                       -       Supports Intel extended page tables (SLAT)

 

but, if I disable "Execute Disable"

coreinfo -v

HYPERVISOR      -       Hypervisor is present
VMX                      *       Supports Intel hardware-assisted virtualization
EPT                       *       Supports Intel extended page tables (SLAT)

 

but this point I can't run VM because "Hypervisor is present" is disable.

I don't understand how enable "EPT" together "HYPERVISOR"

I hope in nice solution.

Regards.
