Installing Linux Angstrom on the Archos 101 IT (internet tablet)

Archos advertises the Linux Angstrom install as if it comes on the device when you buy it.  However it doesn't.  Fortunately, the install is quick and simple, and is actually what's installed when you install the "Software Developer Edition" or SDE.

Download the current SDE from Archos to your computer.

Don't worry about voiding the warranty, it's only the 'software warranty', all hardware related issues are still covered.  The only way you'll have a problem is if you some how manage to brick your device by interrupting an update (so don't interrupt any updates).

Power down your tablet.  Now start the device in recovery mode by pushing the power button and volume down button at the same time, holding the volume down button until the boot loader screen pops up.

Use the up and down volume buttons to select the "update firmware" option, then push power to select it.

Connect your tablet to your computer via a microUSB cable, your computer should recognize it as a mass storage device.  Transfer the firmware image you downloaded onto (root filesystem) your device.  When the transfer is complete, press the power button.  Follow the instructions on your tablet.

To boot into the Linux Angstrom environment, use the same start-up method you previously used to enter recovery mode, and now a boot loader will appear.  Choose the SDE environment.
