Install instructions for Gentoo

(Source: Here, but with changes.)


Link Info

Gentoo Install CD (minimal) Burn on CD at slow speed.

Gentoo Stage 4 tarball (optional) Download it in advance if your net speed is slow. You can download it during installation too. For remote installations, download this in advance and keep it handy on a memory stick!

otheros.bld for Gentoo otheros.default extracted from the Minimal ISO. Use this with the otheros installer.

* Prepare your PS3 for otheros using the instructions here

* Now turn on your PS3 with the Gentoo Install CD in the drive.

* Press Enter to boot the Gentoo kernel - It will boot and configure networking and other settings automatically. Make sure you have a DHCP server on your network (Router or another PC which is sharing the internet connection)

Installation starts now, with the livecd ~ # prompt

Partitioning Disks

livecd ~ # fdisk /dev/sda

The number of cylinders for this disk is set to 10239.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs


Command (m for help): n

Command action

e extended

p primary partition (1-4)


Partition number (1-4): 1

First cylinder (1-10239, default 1): Press Enter

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-10239, default 10239): +9000M

Command (m for help): n

Command action

e extended

p primary partition (1-4)


Partition number (1-4): 2

First cylinder (8585-10239, default 8585): Press Enter

Using default value 8585

Last cylinder or +size or +sizeM or +sizeK (8585-10239, default 10239): Press Enter

Using default value 10239

Command (m for help): t

Partition number (1-4): 2

Hex code (type L to list codes): 82

Changed system type of partition 2 to 82 (Linux swap / Solaris)

Command (m for help): p

Disk /dev/sda: 10.7 GB, 10737414144 bytes

64 heads, 32 sectors/track, 10239 cylinders

Units = cylinders of 2048 * 512 = 1048576 bytes

Device Boot Start End Blocks Id System

/dev/sda1 1 8584 8790000 83 Linux

/dev/sda2 8585 10239 1694720 82 Linux swap / Solaris

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

livecd ~ # /sbin/reboot

This will reboot your PS3. What it will do is force the installer to re-read the partition table. After it reboots, you will be back at the kboot prompt and you can continue your installation from the next step.

Formatting root filesystem and swap + Enabling swap and mounting root

livecd ~ # mkfs.ext3 -j /dev/sda1

mke2fs 1.3x (29-May-2006)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

1098880 inodes, 2197500 blocks

109875 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=2252341248

68 block groups

32768 blocks per group, 32768 fragments per group

16160 inodes per group

Superblock backups stored on blocks:

32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632

Writing inode tables: done

Creating journal (32768 blocks): done

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 25 mounts or

180 days, whichever comes first. Use tune2fs -c or -i to override.

livecd ~ # mkswap /dev/sda2

Setting up swapspace version 1, size = 1735389 kB

no label, UUID=56270620-3485-4396-b65b-269517a5451c

livecd ~ # swapon /dev/sda2

livecd ~ #

livecd ~ # mount /dev/sda1 /mnt/gentoo/

Installing base system, mounting procfs and /dev + Readying for chroot

livecd ~ # cd /mnt/gentoo/

livecd gentoo # wget http://gentoo.osuosl.org/experimental/ppc6...s3_32ul.tar.bz2 (If already downloaded in advance, copy the file to /mnt/gentoo now)

livecd gentoo # tar -xjpf stage4-ppc64-ps3_32ul.tar.bz2

livecd gentoo # mount -t proc none /mnt/gentoo/proc

livecd gentoo # mount -o bind /dev /mnt/gentoo/dev

livecd gentoo # cp /etc/resolv.conf /mnt/gentoo/etc

Chrooting into the base system

livecd gentoo # chroot /mnt/gentoo/ /bin/bash

livecd / # export PS1="(chroot) $PS1"

(chroot) / # env-update && source /etc/profile

--- 'profiles/arch.list' is empty or not available. Empty portage tree?

>>> Regenerating /etc/ld.so.cache...

(chroot) / # emerge --sync (Skip this step if your PS3 is not connected to the internet.)

This will take some time. Go and make yourself a cup of coffee :)

livecd / # export PS1="(chroot) $PS1"

Final configuration steps

Setting timezone:

(chroot) ls /usr/share/zoneinfo

(Suppose you want to use GMT)

(chroot) cp /usr/share/zoneinfo/GMT /etc/localtime

Configuring kboot:

(chroot) e2label /dev/sda1 /

(chroot) / # cd /etc

(chroot) / # cp kboot.conf.example kboot.conf

(chroot) / # nano -w kboot.conf


# The following is an example kboot configuration file. Edit it

# to suit your needs before attempting to reboot your system or

# you may be unable to boot the new install.

# default: the default kernel label to boot should the user not make

# a selection. Uncomment the following line and set a default kernel label.


# timeout: number of seconds to wait for user input before the default

# kernel label is booted. Uncomment the following line and set timeout.


# The format from this point on is within a kernel label. At a minimum,

# you must pass the kernel and root device. The syntax is as follows:


# label='device:<path_to_kernel> initrd=device:<path_to_initrd> kernel_options'


# You should also pass the video options as well. An example of video

# options are as follows:


# 480i = ps3fb:mode:1

# 576i = ps3fb:mode:6

# 720p = ps3fb:mode:3

# 1080i = ps3fb:mode:4

# 1080p = ps3fb:mode:5


# You can review all possible video modes using the ps3videomode application

# provided by the ps3pfutils package. i.e. ps3videomode -v will display

# possibilities.

# The following is an example kernel label. Uncomment and edit as needed.

Gentoo='sda1:/boot/kernel-genkernel-ppc-2.6.16-ps3 initrd=sda1:/boot/initramfs-genkernel-ppc-2.6.16-ps3 root=/dev/ram0 real_root=/dev/sda1 init=/linuxrc video=ps3fb:mode:8 rhgb' (replace video=ps3fb:mode:<required mode id>

Now press Ctrl + X. Then Y to save and exit editor.

Creating mount points for Memory Stick and SD Card (60GB version only):

(chroot) / # mkdir /mnt/memstick

(chroot) / # mkdir /mnt/sd


(chroot) / # nano -w /etc/fstab

# .......

# The root filesystem should have a pass number of either 0 or 1.

# All other filesystems should have a pass number of 0 or greater than 1.


# See the manpage fstab(5) for more information.


# <fs> <mountpoint> <type> <opts> <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

/dev/sda1 / ext3 noatime 0 1

/dev/sda2 none swap sw 0 0

/dev/sr0 /mnt/cdrom iso9660 noauto,ro 0 0

/dev/sdc1 /mnt/memstick auto noauto 0 0 (60GB version only!)

/dev/sdd1 /mnt/sd auto noauto 0 0 (60GB version only!)

#/dev/fd0 /mnt/floppy auto noauto 0 0

# NOTE: The next line is critical for boot!

proc /proc proc defaults 0 0

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for

# POSIX shared memory (shm_open, shm_unlink).

# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will

# use almost no memory if not populated with files)

shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

none /spu spufs default 0 0

Again, Ctrl + X, then Y to save and exit.

Setting root password:

(chroot) / # passwd


(chroot) / # nano -w /etc/rc.conf

# /etc/rc.conf: Global startup script configuration settings

# .....

# XSESSION is a new variable to control what window manager to start

# default with X if run with xdm, startx or xinit. The default behavior

# is to look in /etc/X11/Sessions/ and run the script in matching the

# value that XSESSION is set to. The support scripts are smart enough to

# look in all bin directories if it cant find a match in /etc/X11/Sessions/,

# so setting it to "enlightenment" can also work. This is basically used

# as a way for the system admin to configure a default system wide WM,

# allthough it will work if the user export XSESSION in his .bash_profile, etc.


# NOTE: 1) this behaviour is overridden when a ~/.xinitrc exists, and startx

# is called.

# 2) even if ~/.xsession exists, if XSESSION can be resolved, it will

# be executed rather than ~/.xsession, else KDM breaks ...


# Defaults depending on what you install currently include:


# Gnome - will start gnome-session

# kde-<version> - will start startkde (look in /etc/X11/Sessions/)

# Xsession - will start a terminal and a few other nice apps


Adding xdm to default run-level:

(chroot) / # rc-update add xdm default

Unmount filesystems and rebooting PS3!

(chroot) etc # exit


livecd mnt # cd /mnt/

livecd mnt # umount gentoo/proc/ gentoo/dev/ gentoo/

livecd mnt # umount /mnt/usb/ (optional)

livecd mnt # reboot

Where to go from here
