# Hardware Setup (Main PC)

{% stepper %}
{% step %}

#### 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 <a href="#youre-done" id="youre-done"></a>

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)**](/dma/dma-card-setup/jtag-driver-setup-2nd-pc.md) for instructions.
{% endhint %}

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