(I have the one with the Intel graphics and i5 520M processor)
I had success using ModCD - which is probably the easiest OS X install I have done to date as there was no need to install any kexts manually).
Some initials checks...
- know your busratio for your processor at http://en.wikipedia.....22_.2832_nm.29 (for me, the i5 520M is 18 under the Mult column) **this is important**
- be sure in your BIOS under Config > SATA > Mode Option is set to AHCI
1. Download nawcom's ModCD (as of this writing, it's v0.3) and burn to a CD
2. Boot up laptop using the ModCD (btw, it supports installing to a MBR partition, so if you installed Windows already to one partition, you're good to install OS X to another partition and use boot manager to choose which to boot)
3. At the menu screen, eject the ModCD, place the retail version of OS X (i've used 10.6.3) and press F5 to refresh the screen.
4. IMPORTANT: before selecting to boot up the OS X disc, type busratio=18 (where 18 is your busratio)
5. For me, any supported hardward was auto-recognized and installed kexts for LAN and Audio.
Screen resolution: 1280x800 (set in the com.apple.Boot.plist file under \Extra )
Audio (mute, +/- buttons works)
Update: Display Port (works when booting up to external screen, but not when within osx)
What does not work
SD Memory Card Reader
Intel 5700MHD - AMT Graphics no - full acceleration with QE/CI
5. Be sure to edit your com.apple.Boot.plist file under \Extra and set the Kernel Flag to busratio=18 (otherwise you will need to type this every time you boot into OS X).
Assigning screen shots to the Prnt Scrn (Print Screen) keyboard key
Preference pane that dynamically sets the sleep state of your machine (or even to disable)
I've attached my entire Extra folder for anyone's convenience - which also includes my own slightly modified Theme for those also with more than one OS installed - see attached for a preview.
ModCD v0.3.1 is available with some improvements. (also a usb solution is available too now)
