Read our Technical Note 'ARCNET Windows/DOS Drivers' for information about these Drivers.

Driver Infomation

IMPORTANT: Using an improper driver can cause problems that are not immediately apparent! If you are not the application provider (OEM), you should consult with your application provider to find out which driver is appropriate for your use. Our drivers should only be used if specifically required for driver support — either as a tool for software engineers or if directed by an application provider. Using our drivers when unnecessary can lead to a driver conflict that could be difficult to resolve!
Please read the information.
