11. Source copyrights

The boot code from FreeBSD is under the BSD license. The code taken from the Linux PCI subsystem

and Linux NIC drivers are under GPL. Some source ﬁles have been put under GPL by their authors.

Hence the Etherboot distribution is in general under the GPL, but you may use parts of it derived from

FreeBSD under FreeBSD rules. Simply speaking, the GPL says that if you distribute a binary derived

from Etherboot code (this includes boot ROMs) you have to provide, or promise to provide on demand,

the source code. The full conditions of the GPL are speciﬁed in the ﬁle COPYING.

Here are the copyright details of the source, ﬁle by ﬁle:

Unless specifically noted, a file is under the GPL. GPLed files are in

general either from Linux or have been explicitly put under GPL by the

authors. A few files are inherited from FreeBSD netboot and therefore

can be used under BSD or GPL.
