The Apple TV has a modified version of the OS X Tiger, which allows manipulation with a prefix number. For example, to add new codecs and include support for external drives and network "ball". Disadvantages of this approach are obvious: a reduction in stability and performance through the addition of debris. You need it or not - decide for yourself.
Fans extreme (read hacks), and just curious can be recommended as a basic source Awkward TV wiki. This is perhaps the most complete collection of information on the console.
The most painless way to "hack» Apple TV is to install the patch to stick, created with the help of ATV USB Creator. Owning a curve hands is not recommended, and it is, although the probability of "kill" console using the "Left" patches or attempted self-assembly of these or even higher.
An interesting point: patchstick, ie USB flash drive that is used for patching Apple TV is basically a Linux distribution. However, fans of porn can try put "real» Linux on the console, answering himself previously to the question "why". In the presence of desire, however, you can try to install the Apple TV, and a full-fledged "makos", turning it into a cheap mac. Although personally I would suggest for this purpose to take b / a "Minicom".
What gives patchstick? Access to the file system via SSH consoles, plus the ability to download plug-ins. Speaking of SSH. If you are handy with a bad command line (still climbed console patch? Take a ruler and hit on her hands, saying, "do not have to climb to where you should not") is perfect for file manipulation Fugu or ligament MacFUSE / Macfusion.
By and large, having a connection to the web and SSH access to the console is sufficient to establish NitoTVThe remaining manipulations can be performed directly from the Apple TV interface. What gives NitoTV (almost all of it is downloaded and installed from NitoTV menu item): a minimum set of Perian codecs, the MPlayer, support drives that are connected via USB. Theoretically funtsionala much more, but not the fact that everything will work. Plus, some of the functions that require patching the kernel as easy to guess, is unlikely to significantly improve its performance.
About connecting USB devices to be noted that before rebooting all unnecessary devices should be removed. Otherwise, the top box may require a recovery EEPROM.
By the way, recovery firmware image of the first version may require some manipulation (once was "two"? have to tinker). Exactly how and combo updates "Tiger". Indeed the files you take just anything, but will have to download hundreds of megabytes :)
Generally, the recovery procedure, one embodiment of the system to bring in the original form, is described in the documentation. Keep in mind that it may be useful to you.
It is, perhaps, everything.
Immediately say, that I I do not recommend engaged in experiments to "improve» Apple TV (especially for people without proper training level), and therefore to ask questions like, "How do patchstik" or "I ditched the attachment, as her fix" is useless: they will not be answered and will be deleted when moderation.
