RPi Noob Guide to the Pi image
Page in development so far just layout
The intention of this page is to provide the detail of making a working SD card for a RaspberryPi keeping instructions and explanations jargon free as much as posible and explaining any neccessary jargon as it appears.
Getting an image
What is an image.
An image is a file you download that contains the bare minimum to setup a RaspberryPi SD card. The SD card is that bit of plastic you can put in your camera to store pictures and it is more than capable of acting as the primary disk for your RaspberryPi
The absolute minimum to load a Wheezy image is a 2 Gig (Gigabyte) SD card (there are images that will fit on a 1 Gig but not Wheezy) but you will not have much space so I reccomend a 4 Gig and as a noob have two if you can.
You can move to bigger ones later I started with a 2 Gig I extracted from an old camera and a 4 Gig I scrounged from an old MP3 player
If you have a camera that takes SD cards use the cameras format option its quick and usually works.
Ok most of this page will work around the Wheezy images but should work for any image but your going to need to get an image.
The Wheezy image at this time has two versions and each has two download methods
The older version Wheezy 2012-06-18 Beta is available here
The current one Wheezy-Raspbian-2012-07-15 is on the main download page here
Both give the option of a direct browser download or a download using Torrent.
Torrent is better for the community if you know how to use it but if you do not just let your browser do the work and take the Direct Download either way you will end up with a zip file.
The checksum and using it
On the download page you will see a long string with the name SHA-1 this is the checksum if you think any computer file is a sequence of numbers if you were to add all of those together you would get a result an answer.
Get one of the numbers wrong and the answer is wrong well the SHA-1 is a hexadecimal (base16) total for the zip file you downloaded.
This is actually a lie but as a noob it will do you for now.
There is a little program SHA-1.exe that if you feed it your zip file will calculate an SHA-1 number and if that number is the same one on the download page you can be confident the download worked correctly.
