1. On the host system (your real computer), create a new folder called “System32”. Inside of this create a folder “HostDriverStore”, and within that in turn a folder called “FileRepository”. You will want to end up with this hierarchy:
   System32\HostDriverStore\FileRepository
2. Open File Explorer and go to C:\Windows\System32\DriverStore\FileRepository
   Copy the folder whose name begins “nv_dispsig.” to your new System32\HostDriverStore\FileRepository
3. Navigate to C:\Windows\System32, type ‘nv’ and copy all files beginning with ‘nv’ into your new System32
4. Copy your new System32 onto the Virtual Machine. Unfortunately we can’t just copy and paste, so we use a shared network folder instead:
   • On the virtual machine, enable File sharing by typing “File Sharing” into the Start menu and selecting “Manage advanced sharing settings”
   • Create a new folder anywhere.
   • Open its properties (right click) and open the “Sharing” tab.
   • Select “Share” and add “Everyone” with permissions of Read/Write.
   • The network path to your newly shared folder will be displayed. Locate this on the host machine and copy your new System32 into it.
5. Back on the VM, open File Explorer and simply copy your new System32 folder into C:\Windows
6. Shut down the virtual machine.

Having copied the drivers, we now need to perform one more step, which is to actually enable GPU Partioning on the Host using PowerShell:

1. Open the start menu and type “Powershell”. Run “PowerShell ISE” as Administrator. This will open the Interactive Shell Editor.
2. In the bottom half of the window enter the command Get-ExecutionPolicy, execute with Enter and note the result (Restricted, Unrestricted or Undefined)
3. In the top (editor) half, enter the following:

$vm = "STFC"

Add-VMGpuPartitionAdapter -VMName $vm
Set-VMGpuPartitionAdapter -VMName $vm -MinPartitionVRAM 80000000 -MaxPartitionVRAM 100000000 -OptimalPartitionVRAM 100000000 -MinPartitionEncode 80000000 -MaxPartitionEncode 100000000 -OptimalPartitionEncode 100000000 -MinPartitionDecode 80000000 -MaxPartitionDecode 100000000 -OptimalPartitionDecode 100000000 -MinPartitionCompute 80000000 -MaxPartitionCompute 100000000 -OptimalPartitionCompute 100000000

Set-VM -GuestControlledCacheTypes $true -VMName $vm
Set-VM -LowMemoryMappedIoSpace 1Gb -VMName $vm
Set-VM –HighMemoryMappedIoSpace 32GB –VMName $vm

What this code does is to add a GPU Partition Adapter to the named virtual machine and configure how it maps into the VM’s memory.

1. If you’ve named your Hyper-V Virtual Machine anything other than “STFC”, remember to change this in the first line of the script.
2. If the result of Get-ExecutionPolicy above was Restricted or Undefined, run the command Set-ExecutionPolicy unrestricted.
3. Execute the script in the editor by clicking the green play button in the middle of the toolbar, or using F5 on the keyboard.
4. Consider reverting the execution policy by running Set-ExecutionPolicy restricted
5. Start the VM, type “Device Manager” in the Start Menu, and your GPU should now appear under “Display Adapters”.
