A. A. There are different types of ZIP drivers, internal, external, ZIP-PLUS and all of this will work under Windows NT 4.0.

If you have an internal ZIP drive just ensure you have Service Pack 3 or later installed which provide built in support for internal ZIP drives and will display the drives in Explorer as "Removable drive".

If it is an external ZIP drive you will need to download and install the correct drivers from http://www.iomega.com. All downloaded drivers/tools are self extracting and contain good install instructions.
