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 5.06A includes the following components:
INF V2.60A AGP V4.50C RAID V4.30H IDE Filter V1.20D Raid Tools V5.20
