Thanks fariz for this one. VIA's official Microsoft Windows XP 4-in-1 drivers have just been uploaded to the Drivers Page. They are also updated for other operating systems. The installation utility has been updated. As always, if your system is stable there's no need to update your 4-in-1 drivers, however.
