==Setup Buildroot==

First thing we need to do is setup our buildroot. Most of this is ripped from how-to's around the nets.

<ol>

<li>Install Dependencies:
{{keyboard|content=$ sudo apt-get install quilt build-essential subversion libncurses5-dev zlib1g-dev gawk flex}}</li>

<li>Clone Gits: 
{{keyboard|content=$ mkdir petitboot
$ cd petitboot
$ git clone git://foxbrew.org/ps3linux/petitboot/openwrt.git
$ git clone git://foxbrew.org/ps3linux/petitboot/openwrt_packages.git}}</li>

<li>Link packages:
{{keyboard|content=packages to link are in the file ps3_petitboot_howto}}</li>

<li>Copy the configuration:
{{keyboard|content=$ cp ps3_petitboot_config .config}}</li>

<li>Build: <br />
The first time you build, a cross-compiling toolchain will be downloaded and built. This takes a very long time. Subsequent builds are much quicker (~10 minutes).
{{keyboard|content=$ make V=99}}</li>

== EXTRAS ==

===WIFI(SLIMS)===

'''you can use / to search in menuconfig (thanks jevin)'''

# cd into package folder
# clone my ps3-jupiter fork on github
# enable base system -> wireless-tools, kernel modules-> wireless drivers -> kmod-ps3-jupiter, and Network -> wpa-supplicant(if needed see WPA below) as builtin (*) in menuconfig
# enable networking support->wireless -> wireless-extensions as builtin (*) in kernel_menuconfig (you should highlight wireless to make all the other options appear)
# modify kexec to unmount the new modules also ('''ps3_jupiter_sta''' '''ps3_jupiter''')  

(If you choose (M) it will be compiled but not included in the dtbImage. Useful for debugging a module that hangs the kernel :D)

{{keyboard|content=$ cd package
$ git clone git://github.com/DirtyJerz/ps3-jupiter.git
$ cd ..
$ make menuconfig
$ make kernel_menuconfig
$ cd target/linux/ps3/petitboot/base-files/etc/init.d
$ nano kexec --modify MODULES="ps3_jupiter_sta ps3_jupiter.."}}
<br /><br /><br /><br /><br /><br /><br /><br /><br />

===WPA===

If you use WPA2 as I do, you can apply these patchs to package/base-files to enable a the generation of a wpa_supplicant.conf file. It will also add 2 lines to rc.local to automatically connect to your router on boot.

   Makefile.patch - http://pastie.org/2624949
   image-config.in.patch - http://pastie.org/2624956

put those files in package/base-files and apply the patches with 

{{keyboard|content=$ patch < Makefile.patch
$ patch < image-config.in.patch}}

you can now enter your SSID and wpa2 PSK in menuconfig and wpa_supplicant.conf will be added to /etc in petitboot.

= Compiling petitboot (graf's method) =

* I use petitboot to install and boot Linux from internal HDD of my PS3.
* With petitboot, you will be able to install/boot a Linux kernel from USB, HDD, BD or network.
* Compiling petitboot takes a very long time ( actually, it take a long time during the very first compilation, because it compile the powerpc64 toolchain too, but after that, is you re-launch another compilation, it's "fast" )
* On my Arch Linux x86 it doesn't build without patches
* I created a new openwrt git repository which contains my patches and PS3 NOR and VFLASH block device drivers

At this moment, the official GIT server is down :

{{keyboard|content=$ git clone git://foxbrew.org/ps3linux/petitboot/openwrt.git
$ git clone git://foxbrew.org/ps3linux/petitboot/openwrt_packages.git}}
