BeagleBoard RevC5 updates (Formating SD card)

Hi,

i am using the steps mentioned in this website . http://elinux.org/index.php?title=CircuitCo:CircuitCo/BeagleBoard&oldid=156656. to get my SD card up and running. What does it mean to validate/initialise the SD card with a image provided. does it mean its an updated distro where i can install applications onto(sdcard) and run it as a desktop? Or do i need to update kernals and other files after following the steps?

Regards,

Raj
