Alpha PCI 164-266/300 P2.2 Motherboard Terms of Usage

This document outlines the restricted terms of use for the Alpha PCI 164-266/300 P2.2 motherboard. It is strictly for "bounded use applications only," such as embedded printer or disk drive controllers, and requires approval from OEM Business Segment Marketing and a successful qualification test. Unauthorized use of the motherboard will void the warranty.

The restriction stems from a "behavior anomaly" in the Pass P2.2 Alpha 21164 processor chip integrated into the motherboard. However, applications operating within the design limits of this processor chip are not expected to encounter problems. The document further details how to identify these restricted chips through their part branding, specifically listing Alpha 21164 P2.2 chips with identification codes AA 266 (266 MHz) and BA 300 (300 MHz) as subject to these restrictions. It also mentions that the chip's identity can be determined via software by checking the EI_STAT register field, which will be '2' for P2.2 parts.
