ABOUT VIA Hyperion 4 in 1:
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. For Windows NT users, VIA IDE Bus Mastering
driver is the only driver to be installed to your system

VIA Registry (INF) Driver is to be installed under Windows. The driver will 
enable VIA Power Management Controller.

VIA AGP VxD Driver is to be installed if you are using an AGP VGA card.
VIAGART.VXD will provide service routines to your VGA driver and interface
directly to hardware, providing fast graphical access.

VIA ATAPI Vendor Support Driver enhances compatibility with IDE devices.

VIA PCI IRQ Miniport Driver installs under Windows 98 only. It will
improve the PCI IRQ routing sequence.

Please note: The name VIA Hyperion 4in1 drivers was introduced on 6th December 2002. 
Before that time, VIA developed a driver package named VIA 4in1 drivers or VIA 4in1 
service pack, which was essentially the same package of drivers. The VIA Hyperion 
4in1 drivers continue that tradition, and have retained the version naming sequence.

        You may Install and Uninstall VIA drivers by selecting the proper

        Step 1: To setup the driver, double click the "SETUP.EXE" icon.
        Step 2: Bypass the "Welcome" dialog by clicking "Next"
        Step 3: Choose either Normal install (ticked by default) or Quick Install.

The driver package will automatically detect your operating system and provide the
necessary options by default. If you choose Normal install, the installation program
will display those options and you may untick any options to either not install them
or uninstall them. If you choose Quick install the driver options will not be
displayed they will just be installed. Therefore if you are running the program to
uninstall any drivers, just must chose the Normal install option.

        Step 4: Reboot for drivers to take effect.
