Yet, we bring you another Graf_Chokolo post, but this time he is reportedly close to finishing it. What seems to be a hard task for the dual boot of GameOS & Linux in the PS3, Graf_Chokolo has making it look easy in the eyes as the adventure of PS3 fails security continues.

If i got the right version then i just booted decrypted lv2 kernel 3.56 from VFLASH icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo

Thanks for the images. Just booted your tftp image from VFLASH icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo And i see UDP packets coming from PS3 icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo

Please be patient guys, i’m working day and night on HV reversing and Linux booting icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo Regarding dual boot GameOS+Linux, yeah, it’s definetely doable, i’m implementing it currently icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo Regarding dual boot GameOS CFW + GameOS OFW, is also doable, but harder. In both cases we need a custom HV. All HVs are nearly the same in all firmwares from SONY, and i know it very good and can add functionality, patch or remove it however i want.

Booting Linux from VFLASH/HDD or decrypted LV2 kernel from VFLASH/HDD is just a small proof to SONY how good i know your HV icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo Or should i say now my HV icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo

@Scarface

Without patching HV you cannot get GameOS rights on 3.15 with Linux. So custom HV is still needed. And that is exactly what i’m doing right now, creating custom HV. And with original HV from 3.15 you won’t be able to communicate with Update Manager or Dispatcher Manager e.g.

Just booted petitboot from VFLASH on my 3.41 PS3 icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo Created a new VFLASH storage region of size 16MB and stored there uncomressed petitboot compiled by me with openwrt icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo I only patched HV, didn’t touch any Linux files icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo Sorry marcan, i will stick with petitboot icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo I intend to install Debian Linux on this weekend on my HDD icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo Greetings to SONY icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo OtherOS is back icon smile Dual Boot GameOS+Linux Is Close   Graf Chokolo But now with GameOS features.
