This is a OS study project. It is used to learn how an OS works.
Thanks for the sharing of the followig two projects. https://github.com/cfenollosa/os-tutorial https://web.archive.org/web/20160326062913/http://www.jamesmolloy.co.uk/index.html
All my study is based on the two projects above. cfenollosa/os-tutorial is a very good study material for OS learning. It builds the OS step by step so we can easily learn the OS piece by piece. The reason I want to clone from cfenollosa and change it is to run it in my Ubuntu environement. And I added support for GRUB and run/debug it with bochs.
