Detailed Description

HAL driver for ps2 keyboards.

While ps2 keyboards are rarely seen ever in the real world, the interface still exists and the bootloader, rather than using the ps2 port directly, connects it directly to your system keyboard This gives us an easy way to interact with the keyboard without implementingUSB drivers.
