Internet questions raised

Developing PatienceOS is leaving a breadcrumb trail around the internet, namely:

• How to install the .Net AOT compiler so it can be called from the command line without using the dotnet command
• Including an unused variable corrupts the multiboot kernel
• ilc.exe is emitting the sse instruction, xorps, with --instruction-set base
• io port 0x80 - usage for debugging during OS development
