CoolOS, A Cool Operating System.

What is this?

This is a homemade operating system for i386 (aka AI-32 [aka 'Intel Architecture 32-bit'] ) systems.
In other words, a 32-bit operating system for x86 machines, not ARM.

Some places will say i686, but it almost means the same thing. Just a slight super-set of i386.
