 The configuration happens by writing special values to the command and data ports of the PICs. Fortunately there is already a crate called [`pic8259_simple`], so we don't need to write the initialization sequence ourselves. In case you are interested how it works, check out [its source code][pic crate source], it's fairly small and well documented.

 The main abstraction provided by the crate is the [`ChainedPics`] struct that represents the primary/secondary PIC layout we saw above. It is designed to be used in the following way:

 We use the [`initialize`] function to perform the PIC initialization. Like the `ChainedPics::new` function, this function is also unsafe because it can cause undefined behavior if the PIC is misconfigured.

 If all goes well we should continue to see the "It did not crash" message when executing `cargo xrun`.
