213w ago - Recently Graf_Chokolo revealed that he is working on a PS3 3.55 HV CFW, which will have dual boot Linux built in.

To quote from Dukio: I plan to implement dual boot feature in HV, just like i did on my PS3 3.41, and you can boot with it either gameos or linux or some other system like freebsd. You won’t need any bootos on gameos for that. I will also patch HV and enable more features

I will do it on PS3 slim, first i will resize HDD and add a partition for Linux there

Expect more features coming in as the HV patching continues. Oh, and he is working on a 3.55 FW only at the moment, although on the newer firmware versions is possible according to graf.

Now for 3.55, on other version offsets are different so the code is the same but offsets to patch are different.

When ask about the progress of his lawsuit and if he requires more legal funds, graf_chokolo had to say this:

It's very slow, for now it’s enough i think, thanks.

I have no huge news yet regarding lawsuit but soon I think I will have.

Dual-boot would be one heck of a achievement if somebody could pull that one off. Very interesting.

This weekend PlayStation 3 hacker Graf Chokolo has disabled the PS3 internal HDD encryption, opening the door to possibilities such as dual-boot PS3 Firmware and using the decrypted PS3 HDD in another console.

Download: ps3dm-utils GIT repository: git://git.dukio.com/ps3dm-utils.git / linux hv scripts GIT repository: git://git.dukio.com/linux_hv_scripts.git

To quote: Even without having a PS3 to work with, graf_chokolo is really active in distributing updates and fixes to his PS3 Linux gits. The latest one comes with an interesting update as you can see from his post below. Maybe one step further to a dual boot PS3 FW?

Guys, take a look at "ps3dm_sm set_del_def_encdec_key" command. You can disable/enable virtual FLASH/internal HDD encryption with that And by patching HV process 9 (which sets ATA keys before loading GameOS) you can disable it permanently. It means you could swap your internal HDD and use it on another PS3. But you have to restore the content on it after disabling encryption because all data will be encrypted of course.

Soon i will implement ENCDEC device driver for PS3 Linux and you will be able to experiment with ATA encryption. ENCDEC device is responsible for VFLASH/HDD encryption on PS3.

For more details, see my HV page here: ps3devwiki.com/index.php?title=Hypervisor_Reverse_Engineering

And thanks to PS3 Linux fans who help me to test my ps3dm-utils Huge thanks to you guys. I can have fun with PS3 even without having one actually

And thanks to Dukio for his support with this blog and GIT repository.
