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. Version 3.20b has fixed reinstall issue.
