Module Name:

    .../ntos/hal/alpha/axlbsup.c

Abstract:


    These routines are used to access the 82C106 on various platforms.
    It is local for both Beta and Jensen, but Beta accesses it through
    the Xbus while Jensen accesses it through the Hbus.
    These routines assume that a port number and data is sufficient.
