It's a Windows XP or Server 2003 image builder's nightmare: a new chipset that needs to be supported by your images. Why is it such a big deal? Because new chipsets mean new drivers, or at least new versions of existing drivers. And that includes new mass storage drivers. And adding a new mass storage driver typically means rebuilding and recapturing your Windows XP and Server 2003 images. (This isn't nearly as big of a deal for Windows Vista and Windows Server 2008 as you can inject these drivers without much fuss.)
The first signs of Intel's newest desktop 4 Series chipsets, which include the X48, G43, G45, P43, and P45, are showing up on the Intel site. First up is an updated Intel Matrix Storage Manager driver (iastor, one of our "favorites"), posted today and downloadable from http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=2973. Machines that include these chipsets can't be too far behind.
