IP, and UDP, as well as a home brewn UDP based protocol, "remote disk", which provides random access to a single remote file/device. The Open Firmware flavored boot loader automatically initializes the net stack, searches for a remote disk, and tries to boot from it, if the boot device is a network device (e.g. when loading the boot loader via TFTP). This is quite nice for developing with a two-machine setup, since one doesn't even need to install Haiku on the test machine anymore, but can serve it directly from the development machine. When the networking support in the kernel is working, this method could even be used to fully boot, not just for loading kernel and initial modules. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15689 a95241bf-73f2-0310-859d-f6bbb57e9c96
