Another question unrelated to this series: Does 82540EM still supported by Win2k12? The following link shows that 82540EM were not supported in Win2k12. https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=983 The oldest 825x card supported by 2k12 seems 82574. https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=21694&lang=eng&ProdId=3189 If yes, workaround a buggy driver may be endless work in the future.
