#### 🔌 1. Power Down Your Game PC <a href="#id-1.-power-down-your-game-pc" id="id-1.-power-down-your-game-pc"></a>

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

***

#### 🧩 2. Insert the DMA Card <a href="#id-2.-insert-the-dma-card" id="id-2.-insert-the-dma-card"></a>

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

***

#### 🔗 3. Connect to 2nd PC <a href="#id-3.-connect-to-2nd-pc" id="id-3.-connect-to-2nd-pc"></a>

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

#### ⚙️ 4. Enter BIOS on Game PC <a href="#id-4.-enter-bios-on-game-pc" id="id-4.-enter-bios-on-game-pc"></a>

* Power on your Game PC and **enter BIOS/UEFI setup**:
  * Usually done by pressing `DEL`, `F2`, or `ESC` during boot (varies by motherboard).

***

#### 🚫 5. Disable Virtualization (Required) <a href="#id-5.-disable-virtualization-required" id="id-5.-disable-virtualization-required"></a>

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`

***

#### ⚠️ 6. Optional (If Available) <a href="#id-6.-optional-if-available" id="id-6.-optional-if-available"></a>

* **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.)*

***

#### 🧱 7. Disable Memory Integrity in Windows <a href="#id-7.-disable-memory-integrity-in-windows" id="id-7.-disable-memory-integrity-in-windows"></a>

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.

📖 [Reference – Microsoft Guide](https://support.microsoft.com/en-us/windows/options-to-optimize-gaming-performance-in-windows-11-a255f612-2949-4373-a566-ff6f3f474613)

***

#### ✅ You're Done <a href="#youre-done" id="youre-done"></a>

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

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

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://linked-services-dma.gitbook.io/linked-services-dma-docs/dma-guide/hardware-setup-main-pc.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
