30Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
31
32Intel wireless LAN adapters are engineered, manufactured, tested, and
33quality checked to ensure that they meet all necessary local and
34governmental regulatory agency requirements for the regions that they
35are designated and/or marked to ship into. Since wireless LANs are
36generally unlicensed devices that share spectrum with radars,
37satellites, and other licensed and unlicensed devices, it is sometimes
38necessary to dynamically detect, avoid, and limit usage to avoid
39interference with these devices. In many instances Intel is required to
40provide test data to prove regional and local compliance to regional and
41governmental regulations before certification or approval to use the
42product is granted. Intel's wireless LAN's EEPROM, firmware, and
43software driver are designed to carefully control parameters that affect
44radio operation and to ensure electromagnetic compliance (EMC). These
45parameters include, without limitation, RF power, spectrum usage,
46channel scanning, and human exposure.
47
48For these reasons Intel cannot permit any manipulation by third parties
49of the software provided in binary format with the wireless WLAN
50adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
51patches, utilities, or code with the Intel wireless LAN adapters that
52have been manipulated by an unauthorized party (i.e., patches,
53utilities, or code (including open source code modifications) which have
54not been validated by Intel), (i) you will be solely responsible for
55ensuring the regulatory compliance of the products, (ii) Intel will bear
56no liability, under any theory of liability for any issues associated
57with the modified products, including without limitation, claims under
58the warranty and/or issues arising from regulatory non-compliance, and
59(iii) Intel will not provide or be required to assist in providing
60support to any third parties for such modified products.
61
62Note: Many regulatory agencies consider Wireless LAN adapters to be
63modules, and accordingly, condition system-level regulatory approval
64upon receipt and review of test data documenting that the antennas and
65system configuration do not cause the EMC and radio operation to be
66non-compliant.
67
68The drivers available for download from SourceForge are provided as a
69part of a development project. Conformance to local regulatory
70requirements is the responsibility of the individual developer. As
71such, if you are interested in deploying or shipping a driver as part of
