Hi, I know Intel don't expect to carry further enhancements on IXP 1200 family, maybe that's why you don´t find the SDK. However you can get from the companion CD of this book: JOHNSON, Eric. Et. Al. IXP 1200 Programming. Intel Press. About the installation of the environment I think you will have a little headache, but don't give up. I have collected some files that can be useful for you, Please look at: http://webdiee.cem.itesm.mx/web2/comunicaciones/proyectos/intel.htm#instalac... The page is in spanish bout the majority of documents are in english. I also prepared a log when performed the installation, can be found at: http://webdiee.cem.itesm.mx/web2/comunicaciones/proyectos/IXP1200/LNX 2004-09 Installation log for Brivadeli card IXP1200 V3.txt Hope this helps.
