This page describes the step necessary to get all of the features of the ASUS AT3IONT-I [Deluxe] working correctly. It assumes you already successfully installed Arch Linux and installed the basic software (Alsa for audio, wireless_tools and wpa_supplicant packages for wireless in the Deluxe edition, etc.)
Audio over HDMI
Many ION boards exhibit problems when trying to play sound through HDMI. They usually require a custom ALSA configuration via Template:Filename (or, alternatively, on a per-user basis via Template:Filename).
Also, please note that audio over HDMI currently only works in an X session (graphical environment). If you are trying to get the sound to work when running on a virtual terminal, it won't work. Please see this post on the Arch Forums.
The deluxe edition comes with a few extra goodies, such as DC power on-board, mini-PCI WiFi, RCA stereo output, on-board Blutooth, and an included IR Remote.
Special thanks to pj7 of the Ubuntu forums for putting together a working driver for the receiver.
The included IR receiver requires a kernel module to be built to accommodate it. Apparently, it is a rather tricky little device. It seems to work best with the included remote -- it coverts the included remotes' button presses directly to keyboard keystrokes, but when using another MCE remote it reports to the system the raw code. It seems to understand other signals, but you will need a remote that sends the right signal. This results in limited functionality of the device where it can only use the included ASUS remote, a JP1 Programmable remote (to program the known signals), or a universal remote that has the ability to learn the IR signals of the ASUS remote.
As a result, this section will focus on getting the included remote working with the included receiver, based on pj7's driver.

The Bluetooth chip is an Atheros with a device ID of 0cf3:3002. It uses the ath3k driver which has been included in the kernel since ~2.6.33 and works out of the box with the default Arch kernel.
The wireless chipset is an Atheros AR9285. Template:Command It uses the ath9k driver, which has been included in the default kernel since 2.6.27. In other words, udev should load the driver without problems -- there should be no extra configuration to get wireless working on the ASUS AT3IONT-I.
