Open Firmware

Open Firmware is a type of software that starts up a computer before its main operating system loads. It acts as a bridge, initializing hardware components like the CPU, memory, and storage, and providing a standardized way to configure and test hardware. Open Firmware is platform-independent and uses a command-line interface, allowing users and developers to troubleshoot and manage hardware settings directly. It’s used in various systems, including some Apple computers and servers, promoting flexibility and compatibility during the boot process. Essentially, it prepares the hardware environment for the operating system to run smoothly.
