1. How to downgrade ps3 firmware and jailbreak the console
Way back now, immediately after the turn for the fresh century in fact, Sony Computer
Entertainment was extremely aware of the popularity of Linux when it comes to the durability
associated with a consoles life. So much so which they actually
marketed|promoted|advertised|publicized|commercialized} the capabilities of they're most
recent offering, the PlayStation 2 with what they referred to as PS2 Linux Kit.
The particular kit which included a Linux operating system, Usb key-board and mouse, VGA
adapter|adaptor} for connecting with a standard monitor along with a (ample at the time) 40
GB hard disk drive and Ethernet network adaptor turned its system right into a fully working
internet enabled personal computer. The Playstation 2 hardware at that time was far greater
than an equivalent in price Personal computer and several enthusiasts rapidly found
themselves hoping to get to grips with Linux for the first time. Performance was really really
good with every one of the emulators and many home brew demos able to utilize the
Playstation 2 equipment to achieve some outstanding end results. This kind of led to a
dynamic scene which actually produced games as well as graphical demonstrations
reminiscent of the early C64/Amiga demo scene. Even today a full 12 years down the road
the Playstation 2 popularity continues to be propped up by the activity of this scene.
Fast forward to 2006 along with the Ps2 having arrived at its level of mainstream recognition
Sony announce the Ps3 to a excited market. Just as before the actual specs were
breathtaking together with the inclusion of the RSX graphics controller and the new Cell
processor from IBM very effective at some serious number crunching.
In fact at this point there was a well established group of Playstation 2 Linux people so Sony
were definitely rapid once more to market the Linux capabilities of the Playstation 3 aided by

2. the inclusion of the OtherOS feature. It was quickly followed following the consoles release
with YellowDog Linux targeted at the Ps3.. At this stage Sony wasn't simply promoting the
Playstation 3 as a games console. Under the "It only does everything!" banner the console
had been publicized being a family computer capable of running 'other operating systems', a
media center PC with in-built BluRay player which also enjoyed games.
This really is quite a big difference and it also allowed Sony to pay a smaller duty rate with
imports by having it classified as a pc rather than a video game system.
To your common home Linux user excited about homebrew there was clearly a challenge
however. The moment Sony included the otherOS function in their console they'd limited it!.
That they had constrained access to the RSX graphics driver therefore anything that utilized
graphics needed to rely completely within the cell processor which was also limited in the
amount of cores accessible. Precisely what this essentially meant in tangible terms is the fact
that whatever ran perfectly good using a Playstation 2 in 60 frames a second would certainly
crawl and stutter along at 10 FPS if you were seriously fortunate. You all of a sudden had the
unlikely upshot of a higher specification system like the Ps3 unable to perform even a
straightforward SNES emulator at full speed!
Among the first surprise buyers of the Playstation 3 for its Linux features was the US Military.
These people realized extremely quickly the fact that by connecting multiple Linux running
Ps3's together they could put together a super computer of cell processors for a budget
price. Just how many they did buy is certainly anyone's guess but they have a lot of money
backing them therefore it may be an extremely very scary number! Its worth keeping in mind
at this point the fact that as with many new generation game consoles that are launched, the
initial models are likely to be sold at a loss for the hardware with the followup Software
acquisitions actually making the income. So this was no doubt a distressing thorn in Sony's
side. One which would get much worse with the launch of the PS3 Jailbreak 4.11

3. With it now obvious that native Linux on the Playstation 3 must have been a dead end until
just like the Military and Scientific Institutions you're just inquisitive about straight number
crunching step forward the iPhone hacker and general media flirt George Hotz aka GeoHot.
He soon started poking around inside the Playstation 3 searching for a approach to include
unrestricted accessibility of hardware via Linux. This meant looking to bypass the Hypervisor,
the actual chip in charge of locking usage of specific parts of the machine memory. In the
"Hello Hypervisor, I'm Geohot" article Mr Hotz announced to the world that he had access to
the Hypervisor and full control would shortly be available to Linux. Even though these
preliminary claims appeared to be a little premature and he vanished off the Scene for a
couple months following this claiming to have ceased working on the Ps3 to enjoy time with
other projects others ended up looking at the varied security levels on the Ps3 hardware.
This of course left many shouting How to Jailbreak PS3?
The answer soon appeared.
