#### 🚫 5. 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`

#### ⚠️ 6. 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.)*

#### 🧱 7. Disable Memory Integrity in Windows

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.

***

#### ✅ You're Done

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

> 🖥️ **Next Step:**\
> It is now **recommended to proceed with the second PC (2ndPC) setup** to complete the process. Refer to the [35t Driver Setup (2nd PC)](/skydrift-dma/dma-firmware/35t-firmware-flashing.md) or [75t Driver Setup (2nd PC)](/skydrift-dma/dma-firmware/75t-100t-firmware-flashing.md) for instructions.

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