Patchstick

This is the page about Project Patchstick, a 100% legal way to open up the ATV for hacking without having to open the case.

Primary Goals

• Build our own Darwin kernel that boots on the ATV
• Build our own sshd (probably dropbear)
• Install sshd on the ATV, enable it

Secondary goals

• add more hacks (ericIII's ATVFiles comes to mind)
• make it work from a (small) USB stick
• create an image that can be put on a USB-stick even under Windoze (the no-brain-needed part)
• install wget (or similar) to simplify installation of further features
• ...

Steps to be taken

• get a homebrew Darwin kernel to boot up
• build boot scripts that upload the sshd binary to the ATV, and enable it
