### Power Down Your Game PC

Completely shut down your **main PC (Game PC)** before inserting the DMA card.
{% endstep %}

{% step %}

### Insert the DMA Card

Plug your DMA card into **any available PCI-e slot** on your Game PC.
{% endstep %}

{% step %}

### Connect to the 2nd PC

Use the included **USB data cable** to connect the **JTAG Port** on the DMA card to your **2nd PC** (second PC).

{% 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`
* `NX-Mode`
  {% endstep %}

{% step %}

### Optional (If Available)

* **Disable NX-Bit / Execute Disable Bit** *(Only if listed in your BIOS. If not, skip this step.)*
* **Set PCIe Slot to Gen1** *(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"**

If this section won't load, the setting may already be disabled or unsupported — no action needed.
{% endstep %}
{% endstepper %}

***

## You're Done

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

It is now recommended to proceed with the second PC setup to complete the process. Refer to the [**JTAG Driver Setup (2nd PC)**](/dma-guides/dma-introduction/dma-guides/jtag-driver-setup-2nd-pc.md) for instructions.

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