So far I've been studying Papyrix's code for booting up its hardware & filesystems, as well as text-rendering when it has to report errors. I was very keen to study that text-rendering!

Next it initializes one of 2 UI modes, today I'll study how it chooses which to boot.

1st it checks if the "pending transition" in the saved settings is 1, handling that specially.

1/2?

P.S. The code has evolved since I started my study, so I'm now studying it roughly as it was when I began.
