Need help. Hello, Thanks for your interest on the project. Your first steps should be setting up a FreeBSD development environment. Initial development can be done in QEMU, but you will also likely need a physical box with EFI firmware and a serial port in order to test and debug if necessary. I think your starting points should be to setup a system running CURRENT from svn or git if you prefer, we have an official mirror at: https://github.com/freebsd/freebsd You should get familiar with building FreeBSD from source [0], and then I would also recommend that you look into how to build and install the loader without having to rebuild everything else. The loader is stand alone and small, so just building the loader should be quite fast, and that will be very helpful in order to test your code faster. Regards, Roger.
