Updating to Boot Camp 1.4 beta
If you previously installed Boot Camp beta, you can easily update to Boot Camp 1.4 beta. You don’t need to partition your hard drive again (unless you want to change its size) or reinstall your Macintosh and Windows software or documents, but it’s very important to update the Boot Camp Assistant software, create a new Mac Drivers CD and install the updated software it contains onto Windows. Complete instructions are provided in the Installation and Setup Guide included with the Boot Camp 1.4 beta software.
