No start without bootable SD card

I got myself a RaspBerry Pi and did one mistake: I just started it to see if it works. I did not have an SD card in it and I expected it to show

No bootable medium found

Or something similar. Beware! The Pi will not even start without a bootable SD card in it. Also an SD card that is not bootable does not help. Do not send the Pi back, create a bootable SD card and boot from it.

Create a bootable SD card

http://www.raspberrypi.org/quick-start-guide is incomplete, it does not tell you how to dump your file to SD card, here is how I tried:

dd if=2012-12-16-wheezy-raspbian.img of=/dev/sdc

This worked, the OS came up.

Password

User is pi, password is raspberry

Network

Playing with it in the default config:

tweedleburg:~ # nmap 192.168.178.0/24

Starting Nmap 6.01 ( http://nmap.org ) at 2013-05-23 17:51 CEST
[...]

Nmap scan report for 192.168.178.43
Host is up (0.0036s latency).

PORT   STATE SERVICE

MAC Address: B8:27:EB:06:57:BA (Raspberry Pi Foundation)

NFS Server

Using it as NFS Server I get 8 MB/s when writing on it using the command

dd if=/dev/zero of=datei bs=4096 count=10000

ideas what to do with it

• print server
• NFS server
• surfstation
• firewall
