For 2: Apparently it's broken at the moment, but https://wiki.osdev.org/ is an amazing resource.

It's incredibly satisfying to boot into your own multitasking kernel. Back when I did it back in the late 1900s there were a lot fewer resources like this, and a lot more just working it out from Intel manuals.

It's a lot of fun, and teaches you a lot.

I did the same - booted my own multi-tasking OS in x86 assembly, with osdev.org and alt.os.development being extremely helpful!

... but did you have to call it the 1900s LOL :)

I could have called it the late 1000s. :-)
