+Ablauf:
+  * Mount ISO Image of Mellanox Driver to /mnt/mellanox
+  * Create directory /tmp/build_driver_mellanox
+  * Copy from src directory from iso image the source code to /tmp/build_driver_ mellanox
+  * Copy Conf File to /tmp/build_driver_ mellanox (from MCNG Source Code!)
+  * Start Kernel driver installation ( ./install.pl –c ofed.conf)
+  * Install Tools from rpm directory of iso cd
+Mount the Infiniband Setup ISO Image via the command
+<code bash>
+# mkdir /mnt/mellanox
+# mount -o loop -t iso9660 /installfiles/06_mellanox/MLNX_OFED_LINUX-1.5.3-3.0.0-rhel5.7-x86_64.iso /mnt/mellanox
