==Firmware and microcode==
In cases of [[firmware]] or [[microcode]], it is acceptable for major open-source projects like [[OpenBSD]] to include a binary firmware of a device within the distribution,<ref name="rum"/> as long as said firmware runs only on the external device in question and not on the main CPU where the operating system itself is running. However, for such inclusion to be in place, the binary firmware must be distributed under an adequate license,<ref name="rum"/> like [[ISC license|ISC]] or [[BSD licenses|BSD]], and must not require a discriminatory contract to be in place.<ref name="ipw.awad"/> A lack of such a license is why wireless devices from [[Intel#Open source support|Intel Corporation]] do not work out of the box in almost all open-source distributions, whereas [[Ralink]] wireless cards work just fine.<ref name="ipw.awad">{{cite web|url=http://bxr.su/OpenBSD/share/man/man4/ipw.4#92|title=ipw.4 – Intel PRO/Wireless 2100 IEEE 802.11b wireless network device, Sh FILES|website=BSD Cross Reference, OpenBSD share/man/man4/|quote=These firmware files are not free because Intel refuses to grant distribution rights without contractual obligations.
