Customer Benefits of ServerProven® Program

This program allows Ringdale to submit its line of Madge network server adapter products to IBM for forward and backward compatibility testing on new and pre-released IBM Servers. This helps to ensure the robustness and compatibility of combined Ringdale / IBM server configurations. Customers will welcome the announcement of the ServerProven program as it provides them with additional assurance and confidence that the Madge products have been thoroughly tested in a representative set of environments and provide the ideal building block for their server connectivity needs.

Customers who use Madge server adapters will benefit from an added level of interoperability testing for new products from IBM, thereby decreasing possible downtime and increasing efficiency. To achieve these ends, both IBM and Ringdale have aligned their R&D teams, and have dedicated marketing and service staff to identify and address interoperability issues. In conjunction with its new line of PC Server solutions, IBM has selected the full range of Madge server adapter cards from Ringdale to undergo extensive pre-market testing for compliance with IBM's new PC Server line. The program includes the family of Madge Token Ring server adapters for EISA, PCI, MC and AT architectures. The partnership provides forward and backward compatibility for future adapter products, and is expected to support ATM (Asynchronous Transfer Mode) in the future. For additional information visit
