{% endstep %}

{% step %}

### Enter BIOS on Game PC

Power on your Game PC and **enter BIOS/UEFI setup**:

* Usually done by pressing `DEL`, `F2`, or `ESC` during boot (varies by motherboard).
  {% endstep %}

{% step %}

### Disable Virtualization (Required)

Virtualization interferes with DMA memory access and **must be disabled**.

**Intel CPUs:**

* Disable:
  * `VT-d`
  * `Intel Virtualization Technology`
  * `IOMMU` (if available)

**AMD CPUs:**

* Disable:
  * `SVM`
  * `IOMMU`
    {% endstep %}

{% step %}

### Optional (If Available)

* **Disable NX-Bit / Execute Disable Bit**\
  \&#xNAN;*(Only if listed in your BIOS. If not, skip this step.)*
* **Set PCIe Slot to Gen1**\
  \&#xNAN;*(Recommended for maximum compatibility. Found under `Advanced > PCI Settings` or similar.)*
  {% endstep %}

{% step %}

### Disable Memory Integrity

On your **Game PC**, do the following:

1. Open **Windows Security**
2. Navigate to:\
   `Device Security > Core Isolation > Core Isolation Details`
3. **Turn off "Memory Integrity"**

### ✅ You're Done

Your DMA card is now installed and your Game PC is properly configured.

{% hint style="info" %}
It is now recommended to proceed with the second PC setup to complete the process. Refer to the [**JTAG Driver Setup (2nd PC)**](https://docs.ducks-services.com/dma/dma-card/jtag-driver-setup-2nd-pc) for instructions.
{% endhint %}

If you run into issues, double-check that virtualization is fully disabled and all hardware connections are secure.
