Q1) How do customers purchase a Lotus Foundations 1.2 solution?
A1) Customers purchase Lotus Foundations 1.2 (core software stack) through their local IBM Software Reseller.

In some countries, one IBM Reseller will be able to provide both.
Q2) What are the officially supported platforms for Lotus Foundations 1.2?
A2) The IBM 9234-CNx and 9234-DNx are the officially certified hardware platforms for new purchases of Lotus Foundations solutions. Additional certified and supported hardware platforms that have been tested by IBM or withdrawn from marketing and are no longer available for ordering are provided in
