Module Name:

    ntalpha.h

Abstract:

    User-mode visible Alpha specific structures and constants

Author:

    Joe Notarangelo  27-March-1992  (based on ntmips.h by Dave Cutler)

Revision History:

    Kim Peterson     21-May-1997    Add DNZ bit to FPCR and SoftFPCR

    Miche Baker-Harvey 28-Jan-1993  Add 32-bit API for context structure

    Jeff McLeman     22-Jul-1992    Add SystemTime struct

    Jeff McLeman     10-July-1992   Add Stall entries in the PCR

    Steve Jenness    08-July-1992   Add NtCurrentTeb definition.

    John DeRosa      30-June-1992

            Added volatile qualifier to the address arguments of the I/O
            space function prototypes.

            Put back in sections of the PCR, and a typedef, that were deleted.

    Rod Gamache      15-May-1992    Add EISA access routines prototypes

    Thomas Van Baak (tvb) 9-Jul-1992

        Created proper Alpha CONTEXT structure definitions.
