==== iBook G4 Hardware info: ====
 
iBook G4/1.33GHz 12-Inch (Mid-2005)
 
:*1.33 GHz PowerPC 7447a (G4) processor with 64k L1 cache
:*512k "on chip" level 2 cache.
:*512 MB of onboard RAM (PC2700 DDR SDRAM).
:*40 GB (4200 RPM) Ultra ATA/100 hard drive.
:*Slot-loading DVD-ROM/CD-RW "Combo" drive.
:*4X AGP ATI Mobility Radeon 9550 graphics with 32 MB of DDR SDRAM.
:*A standard AirPort Extreme (802.11g) - Broadcom BCM4318 chipset.
:*Bluetooth 2.0+EDR.
:*56k v.92 standard modem
:*50 W/Hr LiIon battery (Stated 6 hour lifetime)
:*12.1" TFT XGA active matrix display (1024x768 native resolution).
:*"Sudden Motion Sensor" technology that stops the hard drive heads from moving if the notebook is dropped.
:*"Scrolling Trackpad" that allows one to scroll or pan by touching the trackpad with two fingers instead of one.
 
==== Dual booting with OS X ====
 
*Install OS X first:
 
:#Boot from your OS X install CD but before the installation starts, load the disk utility from the top menu.
:#Here you can partion your drive. Partition the drive in two, one as MAC filesystem (for OS X) and one as free space, leave the MBR as the default MAC option.
:#Once OS X is installed grab any updates and set the date/time.
:#You are now ready to go ahead with installing Fedora
 
{{Admon/tip | Setting the date and time in OS X will mean the date is right in Fedora from the point of install.}}
 
==== Installing Fedora ====
 
*Turn on your Apple, insert the Fedora install media and boot from the CD/DVD by holding down the 'c' key as soon as you hear the Apple chime.
 
{{Admon/warning | Note | There seems to be a bug in the Fedora 9 installer. Caps lock may be on when the light is not. Check at the screen where you can enter your host name.}}
 
:# If you are dual booting, when you get to the partitioning page, select the option which will set up the free space on your hard drive for Fedora, leaving your MAC partition alone.
 
==== Wireless networking ====
 
To get a list of current hardware, in which you should be able to spot your wireless card and see what chipset it uses, open up a terminal and as 'root' type:
 
<pre>
# lspci
</pre>
 
===== Broadcom BC43xx chipset=====
 
This chipset uses the 'b43' drivers contained in the kernel. For a comprehensive list of supported chipset versions and more info, check the link at the bottom of the page to linuxwireless.org. Although the 'b43' driver is open source, a proprietary piece of firmware is required in order get this wireless chipset to function.
 
To find out what version you have use a terminal to enter this command as 'root':
 
<pre>
# lspci | grep Broadcom\ Corporation
</pre>
 
The b43 driver with the proprietary firmware currently supports these versions:
 
* bcm4303 (802.11b-only chips)
* bcm4306
* bcm4309 (only the 2.4GHz part)
* bcm4311 rev 1 / bcm4312
* bcm4311 rev 2 / bcm4312 (needs patches for 2.6.24)
* bcm4318 
 
{{Admon/warning | Note | This guide assumes you are using kernel version 2.6.25 or newer (Fedora 9 and above).}} 
 
:*Getting a wireless card running the Broadcom chipset working with Fedora
 
The first thing to do is to grab the firmware and make sure you have the 'b43-fwcutter' tool installed. The firmware cutting tool is used to extract the bit of firmware needed from the proprietary driver.
 
:*Download the firmware:
 
You can get the firmware from the openwrt.org project. Use the 'wget' command below to download it.
 
<pre>
$ wget http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
</pre>
 
Now extract the archive:


<pre>
== Meetings ==
$ tar xjf broadcom-wl-4.150.10.5.tar.bz2
* We don't schedule any IRC meetings, although starting at the Alpha phase of any release we'll try to find some time each day to discuss open issues on our {{fpchat|#fedora-ppc}} channel on IRC .
</pre>
* The last 'real' [https://fedoraproject.org/wiki/Architectures/PowerPC/Meetings/FUDCon_Lawrence_2013 meeting] of the Fedora-PPC team took place at the FUDcon 2013 in Lawrence, Kansas.


You should end up with a 'broadcom-wl-4.150.10.5' directory and inside that a 'driver' directory containing 'wl_apsta_mimo.o'.
== Current Development ==


:*Next, use the 'b43-fwcutter' tool to extract the firmware to your Fedora system:
[[Architectures/PowerPC/CurrentDevelopment]] tracks our current development efforts.


First, as 'root' set an environment variable pointing to where the firmware should be installed on your system:
Also see the [http://ppc.koji.fedoraproject.org/koji/serverstatus dashboard] for constantly updated stats on when the most recent pushes were, number of unsigned packages, most important build failures, etc.


<pre>
== Stable Release, GPG keys ==
# export FIRMWARE_INSTALL_DIR="/lib/firmware"
</pre>


Enter the 'broadcom-wl-4.150.10.5'/driver' directory
Fedora 22 is the latest stable release of Fedora for Power. It was announced on June 2, 2015. Please see [https://fedoraproject.org/wiki/PowerPC/F22/Installation the release announcement] for additional details or download it from your closest [https://admin.fedoraproject.org/mirrormanager/mirrors/Fedora/22/ppc64 mirror].


<pre>
Fedora for Power uses different GPG keys than the primary architectures. Check [https://fedoraproject.org/keys The official Fedora GPG key list] for a list of secondary arch keys.
# cd broadcom-wl-4.150.10.5'/driver
</pre>


and finally run the firmware cutting tool to extract the firmware to your system:
== Supported Architectures ==


<pre>
Only 64bit machines (big endian Power5 or newer and little endian Power8 or newer) are supported, 32bit packages are not available anymore in F22 or newer. The last Fedora release with 32bit boot images was Fedora 17. Although it might be possible to install a 32bit F17 release and then update with the latest F21 packages, this is not supported by the Fedora PPC developers anymore.  
# b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta_mimo.o
</pre>


That's it, upon reboot you should have a working wireless card! I would, however, just load the 'b43' module before the reboot to make sure there are no errors:
Fedora 18 and newer also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected.


<pre>
== Previous Releases ==
# modprobe b43
</pre>


I expect a reboot is not actually necessary, you can probably get away with just restarting the network manager.

Getting Started with Fedora for Power::
Check out our current development efforts and join the Fedora for Power team on IRC in #fedora-ppc[?] on http://freenode.net

PowerPC/POWER Special Interest Group

Members

Meetings

  • We don't schedule any IRC meetings, although starting at the Alpha phase of any release we'll try to find some time each day to discuss open issues on our #fedora-ppc[?] channel on IRC .
  • The last 'real' meeting of the Fedora-PPC team took place at the FUDcon 2013 in Lawrence, Kansas.

Current Development

Architectures/PowerPC/CurrentDevelopment tracks our current development efforts.

Also see the dashboard for constantly updated stats on when the most recent pushes were, number of unsigned packages, most important build failures, etc.

Stable Release, GPG keys

Fedora 22 is the latest stable release of Fedora for Power. It was announced on June 2, 2015. Please see the release announcement for additional details or download it from your closest mirror.

Fedora for Power uses different GPG keys than the primary architectures. Check The official Fedora GPG key list for a list of secondary arch keys.

Supported Architectures

Only 64bit machines (big endian Power5 or newer and little endian Power8 or newer) are supported, 32bit packages are not available anymore in F22 or newer. The last Fedora release with 32bit boot images was Fedora 17. Although it might be possible to install a 32bit F17 release and then update with the latest F21 packages, this is not supported by the Fedora PPC developers anymore.

Fedora 18 and newer also includes several optimized packages for Power7 machines. These will be installed automatically if a Power7 processor is detected.

Previous Releases

You can find information about previous Fedora for Power releases at Architectures/PowerPC/PreviousReleases.

Build System & Resources

Koji

All official Fedora PowerPC packages are built by the koji build system at the PowerPC koji hub

Everyone with a Fedora account can do scratch builds of packages on the PowerPC koji build system. After running fedora-packager-setup from the fedora-packager rpm 

ppc-koji build --scratch f20 yourpkg.src.rpm

Scratch builds can be found here, and will be removed from koji automatically after a while.

For a build to end up in the final Fedora for Power distribution, that NVR must have been built on the primary Fedora koji and then pushed as an update for that release. koji-shadow is used by Fedora for Power to track both the stable (e.g. 'f20' during f20 branched development and 'f20-updates' after GA) and updates-testing tags of each release, as well as the current rawhide tag. Please feel free to find dwa or Kick_ on the #fedora-ppc IRC channel if you have questions about the koji-shadow process.

PPC Shell access for debugging

Brent Baude (rangerpb) or Karsten Hopp (Kick_) may provide you access to a PPC box for build debugging purposes. Just send them an e-mail with an request and a public SSH key.
