IMPORTANT INFORMATION BEFORE USING THIS DRIVER +----------------------------------------------- + +Important Notice FOR ALL USERS OR DISTRIBUTORS!!!! + +Intel wireless LAN adapters are engineered, manufactured, tested, and +quality checked to ensure that they meet all necessary local and +governmental regulatory agency requirements for the regions that they +are designated and/or marked to ship into. Since wireless LANs are +generally unlicensed devices that share spectrum with radars, +satellites, and other licensed and unlicensed devices, it is sometimes +necessary to dynamically detect, avoid, and limit usage to avoid +interference with these devices. In many instances Intel is required to +provide test data to prove regional and local compliance to regional and +governmental regulations before certification or approval to use the +product is granted. Intel's wireless LAN's EEPROM, firmware, and +software driver are designed to carefully control parameters that affect +radio operation and to ensure electromagnetic compliance (EMC). These +parameters include, without limitation, RF power, spectrum usage, +channel scanning, and human exposure. + +For these reasons Intel cannot permit any manipulation by third parties +of the software provided in binary format with the wireless WLAN +adapters (e.g., the EEPROM and firmware). Furthermore, if you use any +patches, utilities, or code with the Intel wireless LAN adapters that +have been manipulated by an unauthorized party (i.e., patches, +utilities, or code (including open source code modifications) which have +not been validated by Intel), (i) you will be solely responsible for +ensuring the regulatory compliance of the products, (ii) Intel will bear +no liability, under any theory of liability for any issues associated +with the modified products, including without limitation, claims under +the warranty and/or issues arising from regulatory non-compliance, and +(iii) Intel will not provide or be required to assist in providing +support to any third parties for such modified products. + +Note: Many regulatory agencies consider Wireless LAN adapters to be +modules, and accordingly, condition system-level regulatory approval +upon receipt and review of test data documenting that the antennas and +system configuration do not cause the EMC and radio operation to be +non-compliant. + +The drivers available for download from SourceForge are provided as a +part of a development project. Conformance to local regulatory +requirements is the responsibility of the individual developer. As +such, if you are interested in deploying or shipping a driver as part of +solution intended to be used for purposes other than development, please +obtain a tested driver from Intel Customer Support at: + +http://support.intel.com/support/notebook/sb/CS-006408.htm 1.
