What's the difference between Pre-Loaded SD card and Original Raspbian?

Recently bought an empty micro SD card and loaded the latest original Raspbian into it. Ended up getting a ended amount of scrolling text until I took the RF board out. What are the additional files I need to load in if I don't want to use the pre-loaded SD card? 

Found lots of guide online but they are mostly for emonPi and uses the pre-loaded SD card.

The Raspbian operating system uses the Pi's serial port on the GPIO for a serial console. By connecting the RFM2Pi without changing any configurations what is happening is the RFM2Pi board, which only needs power to operate is producing a serial output that is believed to be from the user via a console and therefore being displayed much the same way as when you use a keyboard.

You need to edit /etc/inittab and /boot/cmdline.txt to use the serial port differently. this can be done manually, there are dozens of threads on this site explaining how, thousands on the web or if you have a late Raspbian image it has now been included in raspi-config menu.

From there what you need to install depends on what you want, but since you have a RFM2Pi emonhub is the OEM method of interfacing that to send data remotely or use locally.  There is a guide on installing emonhub Emonhub installation/update and that page also explains how to edit the files above.
