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
- 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.
- 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.
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:
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':
# lspci | grep Broadcom\ Corporation
The b43 driver with the proprietary firmware currently supports these versions:
- bcm4303 (802.11b-only chips)
- bcm4309 (only the 2.4GHz part)
- bcm4311 rev 1 / bcm4312
- bcm4311 rev 2 / bcm4312 (needs patches for 2.6.24)
- Getting a wireless card running the Broadcom chipset working with Fedora
The first thing to do is to make sure you have the 'b43-fwcutter' tool installed and grab the firmware.
The firmware cutting tool is used to extract the bit of firmware needed from the proprietary driver. It is a command line tool and should already be installed if you have done a standard Fedora installation.
If you don't have it you can install it using 'yum':
# yum install b43-fwcutter
- Download the firmware:
You can get the firmware from the openwrt.org project. Use the 'wget' command below to download it.
$ wget http://mirror2.openwrt.org/sources/broadcom-wl-126.96.36.199.tar.bz2
Now extract the archive:
$ tar xjf broadcom-wl-188.8.131.52.tar.bz2
You should end up with a 'broadcom-wl-184.108.40.206' directory and inside that a 'driver' directory containing 'wl_apsta_mimo.o'.
- Next, use the 'b43-fwcutter' tool to extract the firmware to your Fedora system:
First, as 'root' set an environment variable pointing to where the firmware should be installed on your system:
# export FIRMWARE_INSTALL_DIR="/lib/firmware"
Enter the 'broadcom-wl-220.127.116.11'/driver' directory
# cd broadcom-wl-18.104.22.168'/driver
and finally run the firmware cutting tool to extract the firmware to your system:
# b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta_mimo.o
That's it, upon reboot you should have a working wireless card! Clicking on the network icon should list all the available networks you can connect to. I would, however, just load the 'b43' module before the reboot to make sure there are no errors:
# modprobe b43
I expect a reboot is not actually necessary, you can probably get away with just restarting the network manager.
The Apple touchpad works with Fedora 'out of the box' but only uses a generic mouse emulation driver. This is quite a big problem with Apple laptops as they only have one mouse button. To gain full functionality (and a very neat 'right button' click) you will need to use the 'Synaptics TouchPad' driver for XOrg/XFree86.
- Using the Synaptics driver
The 'Synaptics' driver should be installed with a standard Fedora install. If you're using gnome, 'System' > 'Administration' > 'Add/Remove Software' can check for you and install if necessary. To install from the command line:
# yum install synaptics
Once installed, it's just a case of editing your '/etc/xorg.conf'. Open up a terminal, log in as root;
$ su -
and load 'gedit';
Your '/etc/xorg.conf' will have a "serverLayout" section, add the input device "Apple TouchPad".
Section "ServerLayout" … InputDevice “Apple TouchPad” "AlwaysCore" … EndSection
Then add the following "InputDevice" section anywhere in the config file:
... Section "InputDevice" Identifier "Apple TouchPad" Driver "synaptics" Option "SendCoreEvents" "True" Option "Device" "/dev/input/mice" Option "Protocol" "auto-dev" Option "SHMConfig" "On" Option "LeftEdge" "0" Option "RightEdge" "850" Option "TopEdge" "0" Option "BottomEdge" "645" Option "VertScrollDelta" "40" Option "HorizScrollDelta" "0" Option "MinSpeed" "0.6" Option "MaxSpeed" "1.5" Option "AccelFactor" "0.1" Option "lockedDrags" "True" Option "TapButton1" "1" Option "TapButton2" "3" Option "TapButton3" "2" EndSection ...
This will give you the ability to scroll with the right hand side of the touchpad, left click by tapping with one finger and right click by tapping with two. If you want to change how the pad works you can find out all the options in the manual here:
- #219540 Game Glest not playable at PPC-arch
- #239713 bootstrap ghc on ppc64
- #453311 pulseaudio does not start
- #457165 Kernel 22.214.171.124-86 and following are not bootable
