To quote: 05/23/2011 For Immediate Release: The beginning of dual-firmware PS3: PS3_Ed2.pdf The technique outlined in the .PDF will help people learn more about 3.6x firmwares.
The solution relies on the implementation of a second NOR/NAND Flash. Some technical limitations have been identified. But time will help us to remove them.
The information in the document is still theoretical for the moment, however please post results from your testing.
We believe knowledge and information wants to be free. Learn what you can and help contribute to making the PS3 scene a better place. Released by No_One.

As a follow-up to the previous Project PNM news, here is another update from PlayStation 3 hacker No_One below.
To quote: Hi mates, I wanted to give you news concerning the PNM project. I really missed time. But I just finished what I call the "stand-alone mode". In this mode, we can do everything concerning the NOR FLASH mangement.
PNM is now working with 2 NOR sockets and 1 "virtual" one which is the PS3 embedded memory. It means for example that now we can dump/update the PS3 NOR like any flasher, but also copy its content to another FLASH and so on...
Next step now consists in wiring the PNM board to the PS3. This is what I call the "PS3 mode". I will do it next week
I will of course give you details, some nice pictures and maybe a video. We are not so far to be capable to dual firmware the PS3 and do some nice progress in FLASH decrypting.
Have fun !
PS: For people asking why I simply didn't use a twice capacity NOR FLASH (32MBytes) instead of 2 NOR FLASH (16MBytes). This is simply because it is easy for SONY to disable the dual firmware feature using what we call the "Product ID". Original NOR has a unique product ID (16Mbytes). A simple check and you cannot anymore use PNM.
