Here’s a little trick I found in Boot Camp – you can save the Windows drivers to disk without the need to burn a CD for them.
Run the Boot Camp Assistant in OS X (it’s in Applications/Utilities) and then click on the Utility menu. Select ‘Save Mac Windows Drivers to a folder…’ and put them somewhere which you can access from Windows – I chose my iPod, for example – and then click OK. Wait a minute or so, then reboot into Windows and install away 🙂 .
Note that you’ll want to grab the latest Boot Camp 1.2 beta before doing this, especially if you’re running Windows Vista like I am (albeit still the beta version). But by doing this you won’t have to waste a blank CD.
