This page briefly documents Debian on Asus Eee Top model ET1602.  It is an all-in-one computer with a 15-inch touchscreen panel.

Please don't use this page to track bugs.  File bugs instead, tagging them with model-specific usertags as described on our [[../../Bugs/About|About Bugs]] page, then link to Debian bug numbers in the [[../|Model]] tables as needed.

== Installation ==

 * Use the [[../../HowTo/InstallUsingStandardInstaller|Standard Installer HowTo]].

No special caveats exist for installation of Debian Wheezy.

== Model-specific issues/status ==

=== General: ===

Rumor indicates that the touchscreen's calibration data is stored in the device. This means that you could theoretically calibrate the touchscreen from a Windows environment, then use it in Linux.

=== Debian Wheezy: ===

802.11 wireless does not work by default. The resistive touchscreen is recognized, and functions correctly during graphical install and in xorg. The hardware volume buttons may not work correctly. The built-in screen's resolution is properly detected by xorg at 1366x768.

=== Debian Jessie (August 2014 pre-testingfreeze): ===

Same as for Wheezy above.

Check the [[../|Model]] tables for any issues that apply to this/these model(s).

== Hardware details ==

Some output from various tools to examine hardware attributes follow.

=== Model ET1602c, Debian kernel vmlinuz-3.14-2-686-pae, version 3.14.2 ===
