How to Install Ubuntu Linux on your PS3

To install Ubuntu Linux on your PlayStation 3, you should have the following:
- A PS3 (duh)
- An Ubuntu Linux LiveCD image
- A blank CD-R or DVD-R
- ISO burning software (Nero, etc.)
- USB Flash Drive
- Kboot Loader (aka otheros.bld, Link Provided Below)
- USB Keyboard
- USB Mouse
Burn the iso-file to a CD.
Download this otheros.bld file and put it on a USB stick or burned media using the path:
/PS3/OTHEROS/otheros.bld
(make a folder on your USB drive or burned media called PS3, then create a folder inside it called OTHEROS. Place the downloaded otheros.bld file inside the OTHEROS folder)
2. Prepare the PS3
We need to format the hard disk to make room for the Other OS on the PS3. Before formatting you might want to backup your saved data.
* Go to [Settings] > [System Settings] > [Format Utility].
* Choose [Custom] and [Allot 10GB to the Other OS].
* Choose [Quick Format] and confirm.When the format is completed, press X to restart the system.
Now insert your USB stick (containing the otheros.bld file) into the PS3 and go to [Settings] > [System Settings] > [Install Other OS]. When you see the screen with Title and Location of the otheros.bld file, press [Start] (X) to install the kboot loader.When the installation completes there will be an info screen telling you to go to [Settings] > [System Settings] > [Default System] and set it to [Other OS].
Insert the Ubuntu installation disc and boot it up by restarting the PS3 (by pressing [Yes] at the [Default System] > [Other OS] prompt).
3. Loading the installer
After a few lines of text, the terminal will stop and display:
This is an Ubuntu Live CDROM
…
If in doubt, just press Enter.
kboot: _
Pressing Enter will start the installation with the kernel loading the system.
After detecting your hardware, you need to partition a disk. Select Guided - use entire disk, select /dev/ps3da 10.7 GB, and format #1 as ext3 and #5 as swap. All options should be the defaults if you have followed this guide, so you should be able to just hit Enter through most screens.
