VIA CHIPSET DRIVERS
4-in-1 driver ('Hyperion')
This driver set contains the INF, AGP, IDEFILTER and IRQ drivers.

The latest 4in1 drivers are suitable for ANY VIA chipset, but they are particularly recommended for:
KT4## series, P4X4## series and newer, for example:
K7 chipsets: KT400, KT400A, KT600, KT880, KM400, KN400
K8 chipsets: K8T800, K8T800Pro, K8M800
P4 chipsets: P4X400, P4X400A, PT800, PT880, PM800, PM880

Use the 4.43 drivers for older chipsets:
MVP#, Apollo Pro## series, KT1##, KN1##, KM1##, KT2##, KN2##, KM2##, P4X2##, P4X3##, P4M2##.

IDE Busmaster Driver
The VIA IDE Miniport driver does not install with the VIA 4in1 drivers. It should only be installed on systems with a VIA chipset and:
- IDE Zip drive, under all Microsoft operating systems, with a 686b southbridge chip
- ATA100 hard drives with Windows 2000 prior to Service pack 1
- ATA133 hard drives under Windows 2000 and Windows XP
- IDE Zip drives under Win2K:
  - install the driver and then set the Zip-Drive to DMA disabled and PIO-Mode 1 in BIOS.
  - Open the IDE Tool provided with Bus master Driver and set the Zip-Drive to PIO-Mode 3.

The VIA Bus Master IDE controller is a high performance Bus Master PCI IDE controller. This "VIA Bus Master PCI IDE Driver" distribution floppy is used to utilize the DMA operation of your Hard disk/CD-ROMs drives in order to release the I/O loading from the CPU. You could refer to the related section to install the driver individually.
