Vimja: Added instructions on how to enable a swap partition on an SD card.

{{warning
|Having a swap partition or a swap file on a Flash based storage medium is a highly controversial topic. Swaping can substantially shorten the life-time of the storage-medium.
}}
Modern wear-leveling-algorithms can compensate some of the disadvantages.
{{note
|Note: For swaping, the speed of the flash card is more important than it is in other areas such as storing data or even games! A faster card can drastically improve the speed of swaping and therefore the speed of your OS.
}}
By default, the OpenPandora does not have swaping enabled at all.
{{note
|If you're primarily using the Pandora for gaming, enabling swap won't bring you any advantages. It will, however, make the Pandora more usable as a general computing device, as it makes running more applications simultaneously possible.
}}

== How much swap ==
It's hard to say how much swap your system should provide. As a hint: The Nokia N900, which is also a Linux based Handheld and comes with 256MB RAM, has a 768MB swap partition enabled by default.

== Swap partition ==
In Linux computing, the standard is to have a separate partition for swaping. The (hexadecimal) partition type ID for a swap partition is 0x82.
On your flashcard, create a partition with that partition type. Let's take the example from here http://pandorawiki.org/Running_Linux_from_an_SD_card, where you're having a swap partition as the third partition on the first SD card.
First we have to 'format' the partition to be a swap partition. As a root-user, you can do that with the command line tool mkswap
<source lang="bash">
sudo su
mkswap /dev/mmcblk0p3
</source>
After that, you have to enable the swap partition. You can do that with the swapon tool
<source lang="bash">
swapon /dev/mmcblk0p3
</source>
To enable the swap partition on boot, we have to add an entry to the /etc/fstab file. In our example, the line would look something like that:
<source lang="bash">
/dev/mmcblk0p3 none swap sw 0 0
</source>
After the reboot, use a tool such as swapon or top to determine wether the swap partition is enabled:
<source lang="bash">
swapon -s
</source>
== Swap file ==
TODO

When installing SuperZaxxon Final, its first boot does not have zRam enabled. Reboot to have it automatically enabled.

To determine if you have swap enabled, run <tt>free</tt> or <tt>swapon -s</tt>

Vimja: Added content from this forum post: http://boards.openpandora.org/index.php?/topic/8486-how-to-turn-on-bluetooth/page__gopid__150717#entry150717

== Bluetooth ==
Is a wireless communication standart that consist of protocols for communication and seperate ones for the content.

To turn Wifi on the Pandora on/off use:
menu ==> "System" ==> "Toggle Bluetooth Status"

To access another device, follow this steps:
* turn on Bluetooth on Pandora
* turn on Bluetooth on the other device
* search on Pandora for other devices
* find device and pair it to the Pandora
**if required enter a Pin code

== Bluetooth Capabilities ==
The pandora comes with the following protocols
*[[OBEX]] for exchanging contacts
*[[AD2P]] for audio streams

=== X to Pandora ===

From another computer to the Pandora, you can:

* Send files?
* Using this application: http://repo.openpandora.org/?page=detail&app=btrecv-slaeshjag-bbgfdg

You cannot:

* Browse files on the Pandora?

=== Pandora to X ===

From the pandora to another computer, you can:

* Send files.

You cannot:

* Browse files on the remote system?

== Audio ==

=== Connecting to Bluetooth Headset AD2P ===
As of [[Hotfix 4]], you have to manually configure a bluetooth headset to pandora.

This method will work on applications that uses codec such as [[Exaile]], [[PanPlayer]] and [[MPlayer]]. It also makes MPlayer very buggy. [http://www.gp32x.com/board/index.php?/topic/59460-request-for-hotfix-6/page__view__findpost__p__949225]
