If you are looking for what the default values of the GPIO pins on your Raspberry Pi B and the first 26 pins of your Raspberry Pi B+ are, then read along.

Lines of GPIO0 to GPIO8 are connected to weak transistor pull-ups to 3.3V while the GPIO lines in the range of GPIO9 to GPIO27 are connected to ground, thus pulled-down to 0V by default on the Raspberry Pi hardware end.

So what this means to you in terms of Raspberry Pi GPIO lines is that GPIO lines between GPIO0 to GPIO8 will be pulled up and having a logic value 1 (3.3V) during startup while the GPIO lines GPIO9 to GPIO27 are pulled down to have a logic value of 0 (0V) by default during start up of your Raspberry Pi.

Hope this helps to someone looking for an explanation for their Raspberry Pi default GPIO values!
