Additionally, Headless Mode will enable services to read your IP Address through plugged in speakers or headphones. It will also flash the IP Address to you on the Raspberry Pi LEDs.

To enable Headless Mode, create a file named "headless" inside the boot file system on the Raspberry Pi's SD card. Create this "headless" file before you boot your Raspberry Pi.

Insert the SD card into your system, and create a file named "headless" in the filesystem labelled "boot".

Insert the SD card into your system. Only the boot filesystem will be made available, because Windows will not be able to read other partitions on the card. Create a file named "headless" on that partition

There are two possible configurations for Headless Mode "DHCP" configuration and "Static" configuration.

If you would like to configure the Raspberry Pi to use DHCP, ''leave the "headless" file empty'', and the Raspberry Pi should be assigned an IP Address dynamically.

If you would like to set a static, non-changing, IP Address on your Raspberry Pi, you will need to modify the "headless" file, adding an IP Address, Gateway, and Netmask, to the file for the configurations to work properly(see samples configs below).

IPADDR=[IP Address of Raspberry Pi]

GATEWAY=[IP Address of router/gateway]

If "RESIZE" is in the "headless" file, the root filesystem will be expanded to the maximum size of the sd card via the service rootfs-resize. If "SWAP"(requires the value in megabytes) exists in the "headless" file, a swap file will be created of the specified size, and then activated.

SWAP=[Size of swap in megabytes]

Static Configuration(without rootfs resizing or swap creation):

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

RESIZE

SWAP=512
