			==DT360==
			There are some differences between the DT336 and DT360, though they are very similar.
			===VIA 6656 WiFi Card===
			There is a Mini PCI Express Wifi card in the DT360. It's a VIA 6656 based card. The most recent drivers can be found at [http://www.viaarena.com/default.aspx?PageID=420&OSID=25&CatID=2590&SubCatID=176 the VIA arena]. There are several issues with this driver:
			* There are no packaged versions of the kernel module (''vntwusb'') because the license is ambiguous
			* The license in the code is "Proprietary", even though it uses GPL-only features, so it won't compile on newer kernels
			* To use WPA, it is necessary to compile a custom version of WPA Supplicant with the ''viawget'' wpa driver, which is not the most up to date version.
			** This custom wpa driver is NOT ''wext'' - this means TabletCFG needs to change the way it generates things
			As of this writing, the most recent version was 1.18. This version does not compile due to the license setting in the code. (If this setting is changed, the code compiles and runs, but does not function.) It does work on the Debian Stale kernel.

			Replacing the PCI-Ex card or using a USB WiFi adapter is the current workaround.
			===Touchscreen===
			The touchscreen is the same as the DT336, but the Y coordinates are inverted. Running penmount's ''gCalib'' fixes this. (Use the SUSE 11 package for the 9000 series touchscreen)
			===Geode Graphics===
			Graphics are provided by the geode xorg driver.
			===Drive Size===
			The flash drive in the DT360 is slightly smaller than the DT366 - by about 26MB. This makes DD images not directly compatible between the two versions.

Contained on this page are my notes for the PadOrbiter. Particularly in regards to the various bits of glue software that make the user experience more convenient.

== TabletCFG ==

[[TabletCFG]] is the Configuration program for setting network parameters on the [[PadOrbiter]]. It modifies various configuration files to configure network parameters for the [[PadOrbiter]] to function properly.

=== Network Configuration Snippets ===

TabletCfg needs to modify various files to configure network parameters for the wireless card. These files are overwritten completely each time the configuration changes.

==== WPA-PSK ====

WPA-PSK requires that a configuration file for /etc/wpa_supplicant.conf and /etc/network/interfaces be modified.

===== /etc/wpa_supplicant.conf =====

ctrl_interface=/var/run/wpa_supplicant
#ap_scan=2

network={
ssid="your_ssid"
scan_ssid=1
proto=WPA RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk=your_psk
}

'''Note:''' Add needed changes for using AES256 WPA encryption.

===== /etc/network/interfaces =====

auto eth0
iface eth0 inet dhcp
pre-up wpa_supplicant -Bw -Dwext -ieth0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant
