Installing a Bootloader Choose a Bootloader Kboot Petitboot Copy to Media /PS3/otheros/otheros.bld Settings -> System Settings ->Install Other OS Settings -> System Settings ->Select Default OS -> Other OS Returning to GameOS Use the ps3-utils: ps3-boot-gameos Force shutdown by holding front power button, Force GameOS when powering on PS3 by holding the button until PS3 beeps twice

Petitboot Features a graphical interface and a text console Works with keyboard, mouse, and game controller Extends all the capabilities of kboot Dynamically detects new boot devices Allows setting of graphical modes Allows rebooting to the Game Os

Petitboot Discovered storage devices are mounted under /var/tmp/mnt, named by their device. For example, /dev/ps3da1 is mounted at /var/tmp/mnt/ps3da1. To boot a kernel, use kexec: kexec -f --append="root=/dev/ps3da1" -l /tmp/tmp/mnt/ps3da1/boot/vmlinux –initrd=/tmp/tmp/mnt/ps3da1/boot/initrd.img petitboot is a work-in-progress: if you have any problems, send email to jk@ozlabs.org.

Using Kboot Not just access to local files, but also NFS, HTTP, FTP, and TFTP. Kboot is based on kexec Using kexec-tools Kexec calls allow a new kernel to be loaded without going through firmware or yaboot again Can be used for speeding up kernel test builds kexec -l <kernel> --append="<options>" --initrd=<initrd> reboot Installing package provides man page Sources http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-kboot/ http://kboot.sourceforge.net/

Kexec Using Fedora 10 kexec-tools # kexec -l /boot/vmlinuz-$kver --initrd=/boot/initrd-$kver.img \ --command-line="`cat /proc/cmdline`" Tab key auto-completion

BusyBox Kboot and Petitboot use Busybox Busybox is a project to go from booting a linux kernel to a shell Minimizes the size of the kernel Provides a minimal set of command such as fdisk, lvm, mount, umount, and vi Start the shell by typing ash at the kboot: prompt

yaboot.conf boot=/dev/ps3da init-message=Welcome to Fedora!\nHit <TAB> for boot options partition=1 install=/usr/lib/yaboot/yaboot delay=5 enablecdboot enableofboot enablenetboot nonvram mntpoint=/boot/yaboot usemount root=LABEL=/" image=/vmlinux-2.6.23-9.ydl6.1 label=ydl6_1080p read-only initrd=/initrd-2.6.23-9.ydl6.1.img append="video=ps3fb:mode:133 rhgb quiet”

Choose Linux Distro Needs to be PowerPC Yellowdog CellSDK part of install Kernel modules are built for ps3 Fedora CellSDK Available Free, easy and current Optimal to build kernel Other Redhat, Ubuntu, OpenSuse, Gentoo

Installing Fedora Successfully did GUI normal install of Fedora 10 PPC DVD (Versions as early as 5 reported) Disable Unnecessary Services Optimize /etc/fstab Configure Wireless or Wired Update Packages

Installing Yellowdog Successfully installed YDL 6.1 RHEL/Centos Based Not as updated as Fedora Cell SDK pre-installed PS3-utils pre-installed Sold pre-installed!

Installing Ubuntu Ubuntu 6.1 last version commercially supported Luckily, the Intrepid Ibex has a PS3 install iso: http://cdimage.ubuntu.com/ports/releases/8.10/release/ Select and install software is longest part Be patient... it stayed at 6% for a long time! sudo apt-get install ubuntu-restricted-extras

Optimizing fstab /dev/ps3da1 / ext3 defaults,noatime,nodiratime 1 1 spufs /spu spufs defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/ps3da2 swap swap defaults 0 0 # nodiratime and noatime save writing to disk access times # Memory from ps3vram module managed in rc.local

Configuring Sound Download Configuration File http://kernel.org/pub/linux/kernel/people/geoff/cell/PS3.conf.alsa Install it as PS3.conf /etc/alsa/cards/PS3.conf /usr/share/alsa/cards/PS3.conf Using a custom kernel build, I had to chmod o+rw /dev/snd/* for it to work

PS3-utils for Linux If not pre-installed, then build them from: http://kernel.org/pub/linux/kernel/people/geoff/cell/ps3-utils/ ps3-boot-game-os ps3-dump-bootloader ps3-flash-util ps3-video-mode?

Preparing the Kernel Source git clone git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-linux.git ps3-linux Create/Backup .config file in ps3-linux directory make help make ps3_defconfig make menuconfig USB HID Boot Protocol drivers

Configure Kernel General Setup Auto append version Advanced Platform Ps3 Cell (SPU) Device Drivers USB Support EHCI UHCI Special HID drivers Logitech Sony

Using ps3vram If you use ps3vram, then you can add over 240Mb of GPU RAM to use as swap Need kernel support Yellowdog has it pre-built Fedora/Ubuntu don't have the module Configure a custom kernel from git Device Drivers -> MTD Block Support Memory Technology Device (MTD) support Self-contained MTD device drivers PS3 video ram

Building the Kernel Edit Makefile version make help make && make modules_install && make install Update the /etc/yaboot.conf with the new kernel information Reboot Test

Booting the Kernel Kboot Use the TAB key to cycle through what is available Type the label that was configured in the /etc/yaboot.conf file http://kernel.org/pub/linux/kernel/people/geoff/cell/ps3-howto/ps3-boot-recovery-howto.txt Petitboot Selecting the kernel with mouse and keyboard Use Alt+F1 to access text console of system Use Alt+F2 to return to the GUI ?Use ssh, http, and other features

Pulseaudio Distribution kernels work fine Custom rolled kernel Have /etc/rc.local chmod o+rw /dev/snd/*

Sharing Files USB NFS Samba FTP HTTP

Flash Adobe flash-plugin? Nope, not for PPC! Gnash? gnash-plugin. Audio only.... Xine? xine-plugin. Not at all... Mplayer? gecko-mediaplayer(Fedora) or mplayer-plugin(Ubuntu) Yes!
