Via has updated their Hyperion all in one package for all Via chipsets. Version 5.06A is available for download, and works with all Via chipset hardware. Ideally, those of you using 7th and 8th gen chipsets such as found on the K8N will get the most out of this update. The driver package includes updates for the AGP driver, integrated RAID if your motherboard supports it and the IDE driver which affects hard drive and optical drive performance.
Those on chipsets older than the KT400 (such as on the A7V333) may find that older drivers are more compatible or more responsive than newer drivers, and upgrading on those systems is not advised. You can download the package from Viaarena.
