Module Name:
alpharef.h
Abstract:
This module defines the reference hardware definitions for Alpha AXP
platforms. Any platform that adheres to these interfaces will be
capable of running all of the common drivers.
Author:
Joe Notarangelo 15-Feb-1993
Revision History:
John DeRosa [DEC] 2-July-1993
Added firmware vendor call definitions that are generic to all Alpha
platforms.
