Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18 Windows Driver

The Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18 is a device driver associated with Intel's mobile processors. It acts as a communication bridge between the processor and the PCI Express (PCIe) bus on the motherboard, which is used to connect various hardware components, such as graphics cards, network cards, and storage controllers, to the processor. This root port driver ensures that the operating system and hardware components connected through PCIe can communicate properly.

The "9 - 9D18" refers to a specific instance of the PCI Express Root Port on Intel's mobile chipsets, which often appear in laptops or portable devices. Installing this driver ensures stable operation of PCIe devices, providing proper connectivity and performance for things like GPU (Graphics Processing Unit) cards, Wi-Fi cards, and SSDs that rely on PCIe interfaces.

How to Install the Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18 Driver on Windows

1. Check if the Driver is Already Installed

Before installing the driver manually, check if it's already installed and functioning properly:

Open Device Manager: Press Win + X and select Device Manager.
Locate the Device: Expand the System Devices section. Look for an entry named something like Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18.
Check for Issues: If there’s no yellow triangle or error symbol, the driver is likely installed and functioning correctly.

2. Download the Latest Driver

If the driver isn't installed or if you're looking to update it, follow these steps to download the driver:

Visit Intel’s Official Website:
- Go to Intel’s Download Center.
- In the search box, type "Intel Chipset Driver" or "Mobile Intel(R) Processor Family IO PCI Express Root Port."
Select the Correct Driver: Make sure to choose the driver that's compatible with your specific version of Windows (e.g., Windows 10, 64-bit). Intel typically packages chipset drivers that include the PCIe Root Port drivers along with other essential drivers for the chipset.
Download the Driver: Once you’ve located the correct driver, download it to your system.

Alternatively, you can also download the Intel Driver & Support Assistant tool, which automatically detects the hardware and recommends the appropriate drivers.

3. Install the Driver

After downloading the driver, proceed with the installation:

Run the Setup File: Locate the downloaded file (typically in your Downloads folder) and double-click it to begin the installation.
Follow On-Screen Instructions: The installation wizard will guide you through the process. Choose Express Installation to install all necessary components or select Custom Installation if you want more control over which components to install.
Restart Your Computer: After installation is complete, restart your system to ensure that the driver is fully integrated.

4. Update the Driver Using Device Manager (Optional)

You can also update the driver directly through Device Manager:

Open Device Manager.
Right-click on Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18 under System Devices.
Select Update driver.
Choose Search automatically for updated driver software. Windows will search for the latest driver online and install it if found.

5. Verify the Installation

After installing the driver, check that it is properly installed in Device Manager under the System Devices section.
Look for Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18 without any warning icons (yellow triangles). This confirms that the driver is working correctly.

You can also run diagnostic tests or check for the proper functionality of hardware components connected via PCIe, such as graphics cards or Wi-Fi adapters, to ensure everything is working as expected.

6. Intel Driver & Support Assistant (Optional)

If you prefer an automated way to ensure your system's drivers are up-to-date:

Download and Install the Intel Driver & Support Assistant from Intel’s website: Intel Driver & Support Assistant.
This tool will automatically detect your hardware and provide updates for all Intel drivers, including the PCIe root port driver.

Conclusion

The Mobile Intel(R) Processor Family IO PCI Express Root Port 9 - 9D18 driver is important for ensuring the proper communication between your Intel mobile processor and PCIe devices in your laptop or portable device. By downloading, installing, or updating the driver, you can ensure that your system runs smoothly, with devices connected through PCIe ports functioning correctly.
