[Don't think I've come across GitBooks before this -- looks like something we could use on a project so, bonus find! Thanks!]
I worked on the osx86 acpi stack wayyyy back in the day when the p4 dev kits(that was almost 15 years ago!!!) we're still going out. The sorta stuff that we were doing back then left me thinking that OSX on commodity hardware would always be a pipe dream. To see that transformed into systems that can recieve updates and still function has been really exciting. Good work!
