Koroush "Persian Immortal" Ghazi has updated his original VIA Driver Guide in our forums to come in line with the release of VIA's new Hyperion 4-in-1 drivers which emerged on the Internet yesterday. Word has it PI may be writing up a more in-depth Hyperion guide over the next couple of days, but this should tide you over until that time.
What Are The VIA Hyperion Drivers? - The VIA Hyperions were introduced on 6th December 2002. Before that time, VIA developed a driver package named the "VIA 4in1 drivers" which was essentially the same package of drivers. The VIA Hyperion 4in1 drivers continue that tradition, and have retained the version naming sequence, starting at version 4.45. Eventually the "4in1" part will be dropped and they'll simply be referred to as the "Hyperions".More information in our VIA Discussion Forum
Which Drivers Are In The Hyperion Package? - Just like the 4in1 driver package, the Hyperion includes four system drivers to improve the performance and stability of systems using VIA chipsets - especially the latest P4X400 and KT400 VIA chipsets. More information and benchmark comparisons from VIA about the performance boost for these chipsets can be found here.
