VIA Hyperion Pro drivers are suitable for ANY VIA chipset - but they are particularly recommended for KT4## series, P4X4## series and newer, for example:

Version 5.06A includes the following components:

Since the Hyperion Pro package includes SATA/RAID drivers whilst the Hyperion 4in1 package does not, the extra contents makes the Hyperion Pro package over 5MB larger than the Hyperion 4in1 package. Therefore if you are not utilizing a VIA SATA or RAID controller in your system, the Hyperion 4in1 package may be a better download choice.

Supported Operating Systems:

Windows 2000, Windows XP, Windows 98, Windows XP 64-Bit, Windows ME, Windows 98SE, Windows NT, and Windows Server 2003 x64.

To install the driver, save any unsaved work and close all applications then click on the driver download link (above). Choose the "Save File" option and save it to your folder under Windows where you file your drivers. Unzip the file. (To unzip the file right click and highlight "Extract All") Then double click on the Setup.exe file to run the installation program. Follow the prompts and restart at the end of the installation.
