Find Device ID for OpenCore PCI: A Comprehensive Guide

Introduction

Hey readers! Welcome to our comprehensive guide on finding device IDs for OpenCore PCI. Whether you’re a seasoned tech wizard or just starting to explore the world of PCI, this guide will equip you with all the essential knowledge you need.

OpenCore is a bootloader that allows you to customize your system configuration on macOS-based machines. Understanding device IDs is crucial when using OpenCore, as it helps you identify specific hardware components and configure your system accordingly.

Identifying Device IDs with System Profiler

System Profiler Overview

Open the System Profiler application on your Mac (located under Applications > Utilities). This tool provides detailed information about your system’s hardware and software.

Finding PCI Device IDs

Navigate to the "PCI" category within the System Profiler. Expand the "PCI Cards" section to view a list of all PCI devices installed on your system. Each device will have a unique "Vendor ID" and "Device ID" associated with it.

Extracting Device IDs from Kernel Log

Kernel Log Overview

The kernel log contains a record of events and messages generated by the macOS kernel. It can be accessed through the Terminal application (located under Applications > Utilities).

Extracting PCI Device IDs

Enter the following command in the Terminal:

sudo dmesg | grep -i "PciRoot"

This command will return a list of kernel log messages related to PCI devices. Look for lines that start with "PciRoot(0x0)" and contain "VendorId" and "DeviceId" values.

Using External Tools

PCI Utility

PCI Utility is a free utility designed specifically for handling PCI devices. You can download it from the app store or the developer’s website. Once installed, launch PCI Utility and select the "PCI devices" tab. This will provide you with a list of all PCI devices and their respective IDs.

lspci Command

If you prefer using the command line, you can use the lspci command to list all PCI devices and their IDs. In the Terminal, enter the following command:

sudo lspci -v
