1) The HyperionPro package includes SATA/RAID drivers whilst the Hyperion 4in1 package does not. The extra contents makes the HyperionPro 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.

2) The HyperionPro package supports 64 bit Microsoft Windows XP and 64 bit Windows Server 2003 whilst the Hyperion 4in1 package only supports 32 bit operating systems.

3) Compared with the previous Hyperion Pro driver package, version 5.00A, this version does include the IDE Filter driver, V1.20D. For Win9X/ME/2K the IDE filter driver is needed to support UDMA 6. The IDE Filter driver is not needed for WinXP SP1 and later Microsoft operating systems

Version 5.09A includes the following components:

INF V2.70B
AGP V4.50E
V-RAID V5.30C and RAID Tools v5.30
