No DOS and Windows 3.1 drivers are available for CardBus chipsets necessary to support the Adaptec APA-1480, it cannot be used in DOS as a route to a backup device such as a tape drive, CD ROM, or external Hard Drive. Drivers from a 3rd party source are required to support the CardBus chipset under Windows NT 4.
Microsoft provides built in driver support in Windows 95 and 98. The Adaptec APA-1480 CardBus card is only supported in 32-bit operating systems such as Windows 95, 98, and NT 4 because these are the only Operating Systems that have drivers available for the CardBus socket that supports the 1480.
