# Firmware and drivers Device firmware and drivers are necessary for graphics and also security. Luckily the graphics drivers will be installed through `home-manager` which now only leaves the CPU firmware. For Intel systems install `intel-ucode` and for AMD systems install `amd-ucode`: ``` # apk add intel-ucode # apk add amd-ucode ``` To make sure it is included during boot, regenerate the initramfs with: ``` # apk fix kernel-hooks ```
