Use
This is an internal call for OS use only and should not be used by user software.
Called when the Kernel is ready for the HAL to start scanning the keyboard for boot-time keys. The scan must happen under interrupts – the HAL should arrange for its keyboard controller to be set up to generate interrupts, and for the appropriate interrupt to be unmasked in the IRQ controller.
