42w ago - Following up on his previous work, today PlayStation 3 developer glevand has made available a Linux Cold Boot 3.55 Custom Firmware (CFW) OtherOS++ for PS3 Slim users via Gitbrew that loads into Petitboot with a single button press.

Download: PS3 Linux OtherOS++ Cold Boot Custom Firmware (CFW) / PS3 MFW Patch LV1 OtherOS++ Cold Boot Fix to Patch_LV1.tcl

To quote: Hmm, it would be really nice to cold boot Linux on SLIM. The problem is this. On SLIM we patch GameOS loader and add the OtherOS++ support.

The OtherOS++ loader reads Petitboot from VFLASH and loads it in case the OtherOS flag is set. But at cold boot we cannot access VFLASH immediately, that doesn't work, i tried even to implement retries with sleep calls, no chance.

And today i took a look at GuestOS loader in LPAR1 process 9 (LV1 3.15) and noticed the following interesting thing. It doesn't matter on old OtherOS if we want to cold boot OtherOS...

105w ago - Today PlayStation 3 hacker Cyberskunk has released a Rebug PS3 CFW Boot OtherOS++ and OtherOS Prep Tool for Linux fans alongside a Rebug 3.41.2 & 3.55.1 Custom Firmware (which allows PSN access using this guide via SP-INT) and details on how to add OtherOS++ support.

From their page: Boot OtherOS++ does what it says. One click easy. OtherOS Prep Tool is used to prepare your system vflash and install petitboot ready to install Linux. IT DOES NOT INSTALL LINUX. For tutorials and videos on how to install Linux head over to gitbrew.org.

OtherOS Prep Tool is based off of graf_chokolo’s and glevand’s source and is a one or two step solution to getting petitboot up and running and on your way to installing Linux on to USB or PS3 Hard Disk. At the moment it only supports 3.55 but we will add support for lower firmware soon.

REQUIREMENTS

• 16MB NOR PS3 (Model CECHH or Higher)
  
• 3.55 OtherOS++ enabled firmware installed
  

(If you want to use REBUG 3.55.1 grab PS3MFW Builder 0.2 Portable from here with the tasks pre-selected to add OtherOS++ support)

FEATURES
