How to Find Out PCI Device by Location Path

PCI devices are an essential component of your computer system, allowing it to communicate with various hardware devices such as graphics cards, network adapters, and sound cards. Sometimes, you may need to find out the PCI device by its location path, especially when troubleshooting or updating drivers. In this article, we will guide you through the process of finding the PCI device by its location path.

What is a Location Path?

A location path is a unique identifier assigned to each PCI device in your computer system. It helps the operating system to identify and communicate with the specific device. The location path consists of a series of numbers and letters, typically in the format of "bus:device:function". Each component in the location path represents a different aspect of the device's location and function within the PCI bus.

Method 1: Using Device Manager

The Device Manager is a built-in Windows tool that allows you to manage and view all the devices connected to your computer. Follow the steps below to find the PCI device by its location path using the Device Manager:

1. Press the Windows + X keys on your keyboard and select "Device Manager" from the menu that appears.
2. In the Device Manager window, expand the "System devices" category by clicking on the arrow next to it.
3. Locate and right-click on the "PCI bus" or "PCI Express Root Port" device and select "Properties" from the context menu.
4. In the Properties window, navigate to the "Details" tab.
5. From the "Property" drop-down menu, select "Location Path".
6. The value in the "Value" field represents the location path of the PCI device.

By following these steps, you can easily find the location path of a PCI device using the Device Manager in Windows.

Method 2: Using Command Prompt

If you prefer using the Command Prompt, you can also find the location path of a PCI device using the devcon command-line tool. Here's how:

1. Open the Command Prompt by pressing the Windows + R keys, typing "cmd", and hitting Enter.
2. Type the following command and press Enter: devcon find * | find "PCI"
3. A list of PCI devices along with their location paths will be displayed in the Command Prompt window.

Using the Command Prompt and the devcon tool, you can quickly find the location path of a PCI device without going through the Device Manager.

Method 3: Using Third-Party Software

If you prefer a more user-friendly approach, there are several third-party software programs available that can help you find the location path of PCI devices. These programs provide a graphical interface and additional features for managing and identifying hardware devices. Some popular options include Speccy, HWiNFO, and CPU-Z. Simply download and install one of these programs, and it will automatically detect and display the location path of your PCI devices.

Now that you know how to find the PCI device by its location path, you can easily troubleshoot and manage your computer's hardware devices. Whether you prefer using the Device Manager, Command Prompt, or third-party software, these methods will help you identify the location path of your PCI devices.
