    The installer will warn you if you attempt to compile any of the
    above packages and do not have the prerequisites installed.
 
-*** Important Note for open-iscsi users:
-    Installing iSER as part of OFED installation will also install open-iscsi.
-    Before installing OFED, please uninstall any open-iscsi version that may

-    another open-iscsi version is already installed will cause the installation
-    process to fail.

+a. It is possible to rename and/or edit the ofed.conf and ofed_net.conf files. 
+   Thus it is possible to change user choices (observing the original format). 
+   See examples of ofed.conf and ofed_net.conf under OFED-X.X.X/docs.
+
+b. To make debugging kernel issues easier, we recommend setting the following
+   environment variable before building OFED: 
+   export OPENIB_KERNEL_EXTRA_CFLAGS=-g
+   This will attach debug info to generated kernel binaries without affecting
+   their speed.
+
+c. Important note for open-iscsi users:
+   Installing iSER as part of OFED installation will also install open-iscsi.
+   Before installing OFED, please uninstall any open-iscsi version that may
+   be installed on your machine. Installing OFED with iSER support while
