Angstrom is the distribution on which the Always Innovating OS is based.

Creating your own images

Angstrom's online rootfs builder can be used to build custom Angstrom images for the Touch Book.

As with any OS on the Touch Book, you will need to set up your SD card correctly. Also, unless you intend to solder on a serial cable and change the boot parameters, your root partition must be ext3 at /dev/mmcblk0p2. Note that, if your SD card already had the AIOS installed on it, it should already be properly configured.

To allow the included wireless dongle to function, you will need to copy /etc/Wireless and /lib/modules/2.6.29-omap1/kernel/drivers/net/wireless/ from the AIOS image into your new rootfs. Also, you will need to use the kernel included with the AIOS image rather than the kernel included with the Angstrom image. On booting, you will need to load the module (modprobe rt3070sta); if you want it to load automatically on boot, append it to the modules list (echo rt3070sta >> /etc/modules).

This should give you a fairly functional mostly-stock Angstrom image!
