All tools beep twice if they succeed !!!

Source code for all tools and patches is freely available. Create your own dual boot.


  • Into HV integrated OtherOS bootloader loader (compatible with OtherOS bootloader on 3.15)
  • OtherOS bootloader is booted directly from HV, no GameOS is involved.
  • Process of booting OtherOS bootloader loader is very similar to 3.15 method
  • Booting Linux from HDD/USB/BD/Network
  • Linux with GameOS rights
  • Full access to all HV SS services (Dispatcher Manager) from GameOS or Linux
  • Full access to all System Manager services
  • Ability to create/modify/remove repository nodes in LPAR 1 (e.g. with ps3dm-utils or ps3hvc-utils).

    This ability gives you much power over the whole system because many layers of PS3 use repository nodes to exchange information.
  • Enabled QA mode in Update Manager
  • Downgrading without USB dongle or Service Mode
  • Ability to deactivate/activate HDD/VFLASH encryption (e.g. with ps3stor-utils)
  • Suuport for ps3-utils. You can flash new OtherOS bootloader from Linux e.g.
  • Tested 3.41 and 3.55 on PS3 Slim with Gentoo and Debian Squeeze but should work on PS3 Fat without problems
  • Bug reports are welcome, send it please to
Work in progress:
  • Creating OtherOS partitions directly on HDD (not VFLASH)
  • Permanently disabling HDD/VFLASH encryption
  • Mapping of HTAB with R/W permission
  • SYSCON access from LPAR 2
  • FreeBSD support

Installing OtherOS bootloader

  • Tested ONLY on PS3 models with VFLASH
  • During deleting of VFLASH regions GameOS will ask you to reinstall firmware, don't do it, just press PS3 button and continue
  • I use petitboot as OtherOS bootloader. You could use a different one.
  • The following order of steps is important
  • Delete VFLASH region 6
  • Delete VFLASH region 5
  • Create VFLASH region 5
  • Create VFLASH region 6
  • Install OtherOS bootloader on VFLASH with "Install OtherOS"

Booting OtherOS bootloader

  • Run "Boot OtherOS"
  • Reboot GameOS with "Reboot"

Creating a VFLASH partition for Linux

  • Works ONLY on PS3 models with VFLASH
  • Warning: All your HDD data will be lost, so make a backup
  • I'm currently working on a solution for PS3 models with NAND flash
  • Resize VFLASH (creates a 40GB free space on VFLASH, if you need more then feel free to recompile it)
  • Reboot GameOS
  • Create VFLASH region 7

Installing Linux with petitboot

Installing Gentoo GNU/Linux from a Unix/Linux System

Partitioning with fdisk

  • I used petitboot to install Debian and Gentoo on VFLASH
  • I used fdisk to partition ps3vflashh
  • Make sure you create a swap partition
  • Creating a ready to use Linux distribution images is a work in progress

Booting Linux with petitboot

  • USB driver in petitboot has problems on PS3 Slim. The problem lies in Linux USB driver.
  • Currently i'm trying to fix this problem in Linux kernel
  • I temporarily use my script to boot a Linux installed on VFLASH from petitboot
