Okay. This took me forever to figure out but the answer is reall simple. I am putting this quick tutorial together because I couldn't find one before. If you have a MacBook Pro, XP and an external monitor and you want to run the MBP with the cover closed and the external monitor on... 1. http://support.amd.com/us/gpudownload/Pages/index.aspx 2. Go to the bottom (see attached) and find Apple Bootcamp. Select your options. 3. It asks if you want to download the drivers as well as the Control Panel. You just need the control panel. 4. Install the Control Panel. Reboot if necessary. NOTE: ecpect an error message upon reboot that says this panel isn't compatible with the provided ATI drivers (the ones on Apple's Bootcamp DVD). Ignore the warning. 5. Click on the desktop and select properties, then screen saver tab, then power (at the bottom). Go to the advanced tab and about halfway down change "When I close the lid of my portable computer" to "do nothing". Save. 6. Click on the ATI logo in your toolbar (next to the clock). Select basic setup (the wizard). Keep clicking until you see a bunch of monitors. Select your external one and it will come on and your MBP will go off. Save and reboot. Close cover. It should boot up on your external monitor and the Apple light on the back of your MBP will be off. 7. When it boots up you will get that ATI error message again. Go to Start then Run. Type and open "msconfig". Go across to the Startup tab and uncheck CLIStart and save. THAT'S IT!
