Triple Booting Your MSI Wind

Basic Questions

Why the MSI WInd?  Because it's hardware is the most compatible with OS X.  Just about everything works right out of the box.  I have not verified this, but I think the only thing that does not work with OS X are the external audio ports for headphons and mic.

Why the U100 model? It more upgradeable that the newer models like the U120.  It was easy to add an extra 1GB of RAM.

Dual or Trippe booting?  Multiple OSes is a desirable thing for a geek.  It is not hard.  Check out my guide here.  In summary, I am booting Windows 7 RC, OS X, and Ubuntu Linux using GRUB.

Upgrading Hardware

Like I mentioned above, I decided to get the U100 model because it is upgradable.  Upgrading the wireless, hard drive, and memory is simple.  Simply unscrew the 9 screws on the bottom and pop off the bottom cover, and then all of the upgradeable components are accessible.  Note: one of the screws is covered by a warranty voiding sticker.

Installing OS X

1. Download MSIWindosx86.iso: Just Google the file name MSIWindosx86.iso and it should be the first link.  Download the iso with your torrent client, then burn the ISO to a DVD-R.  This will create a MSI Wind optimized OS X 10.5.4 install DVD

2. Install OS X:  Installing OS X with the MSI Wind specific ISO is a trivial affair.  There is no customization needed.  You will probably have to repartition the drive which you can do with the "Disk Utility."  I am not sure if it matters, but I set my boot partition to use MBR instead of the GUID type.  After the install is complete, you will be running a working OS X 10.5.4 install.  This processes takes over an hour.  All of the hardware is working at this point except the wireless card

3. Install the wireless driver: Note the U100-432US model comes with a Ralink RT2700E b/g/n wireless card.  Lucky for us Ralink provides Mac drivers for us.  The card won't work like the fancy built in OS X wireless utilities, but it does work and that is what matters most.  Go to the Ralink Macintosh Page and download PCI/mPCI/CB(RT2860/RT2790).  Once it is downloaded, install it.  It will put an app in your dock.  You will have to use this app to get on to wireless networks.  Connecting to a wireless network is a two part opperation: first connect to your access point (AP) from the site survey tab, second create a profile on the profile tab for you AP.  After that, you should automatically connect to that AP.  I think this is all that is really needed, but in reading other guides, there were some other steps: go to "System Prefrences" -> "Network" -> "Ethernet 2", click the gear icon and remane it to "Wireless", click the "Advanced..." button and create an 802.1X profile.

4. Upgrading to OS X 10.5.6:  Download this zip file referenced in the msiwind.net wiki.  Make sure you have a USB keyboard and mouse handy.  Next install all of the updates uncluding the 10.5.6 update.  After it is done installing the 10.5.6 update and reboots, your screen will be at 800x600 and your keyboard and mouse will not work.  This is where you plug in the usb keyboard and mouse.  Open the zip folder "Everything You Need" that you just downloaded.  Execute the installer MSIWindDrivers.mpkg to put the dirvers back on.  Next go to the "Item 4" folder, run "Kext Helper", and drag the three kext files into the program.  Reboot, and everything should be good.

 Pitfalls 

Selecting "Mirroring" for your secondary display:  this will make it so both of your screens don't work.  I found this fourm post that fixed it for me.  This is the important bits:

rm /Library/Preferences/com.apple.windowserver.plist
rm /Users/(your-user-name)/Library/Preferences/ByHost/com.apple.windowserver.(bunch-of-characters).plist
