VIA Hyperion 4 in 1 driver includes four system drivers to improve the performance and maintain the stability of systems using VIA chipsets. These four drivers are: VIA Registry (INF) Driver, VIA AGP VxD driver, VIA ATAPI Vendor Support Driver and VIA PCI IRQ Miniport Driver.

VIA Hyperion drivers are suitable for any VIA chipset and all Microsoft Windows Operating Systems (Win95/98/98SE users, see **Note below). If you are looking for VIA 4in1 drivers, these are the drivers you are looking for. The "Hyperion" name was added to the 4in1 driver set name in December 2002. This is the third release with the Hyperion name. You can find more information here.

**Note: Win95/98/98SE are now relatively old operating systems, and drivers are no longer optimized for those operating systems. Many users of VIA chipsets who run Win95/98/98SE report that using an older version, such as VIA 4in1 version 4.35, they experience a more responsive system.

Note: Before proceeding with your driver installation we suggest you make sure you are installing the latest version available and for the appropriate model/revision and Operating System. We strongly suggest following 'readme' instructions for installing drivers when available. Often restarting your system will be necessary for the new driver to become active and start functioning properly.
