Example source code folder path

Respected Sir/Madam,

                   I have recently bought a FriendlyARM mini6410 kit and
after going through the linux user manuel i am trying to locate the
FriendlyARM folder in the OPT directory as mentioned in the manuel but i am
not able to find any,the only folder present in the OPT directory are
Qtopia and Qtopia 4.4.3.
                   Kindly let me know where can i locate the various
examples source codes that are mentioned in the LINUX USER manuel.

                   Your response will be be very helpful,i am locating the
FriendlyARM folder in the linux kernel that has came in the DVD alongwith
the kit.
