The article describes the process of installing NetBSD 11 on a Raspberry Pi 4, a unique endeavor as NetBSD is one of the few open-source operating systems not incorporating AI components. To achieve this, one must first download the latest NetBSD arm64 image and Raspberry Pi UEFI firmware, then use Balena's Etcher to flash the NetBSD image onto an SD card. After flashing, the SD card's boot partition must be mounted and files from the UEFI firmware directory copied to the mount point, allowing the UEFI BIOS to boot NetBSD. The author provides a step-by-step guide, assuming the user is working on a Linux system, to help others replicate the process and successfully run NetBSD 11 on their Raspberry Pi 4.
