Operating Systems
DEC OSF/1
AXP Operating
System
DEC OSF/1 AXP is Digital Equipment Corporation’s
implementation of the Open Software Foundation (OSF)
operating system components and Motif graphical user interface
and programming environment.
Description
of DEC OSF/1
AXP
DEC OSF/1 AXP is compliant with the OSF Application
Environment Specification (AES), which specifies the interface
to support portable applications designed to run on a variety of
hardware platforms.
In addition, the DEC OSF/1 operating system complies with
these standards and industry specifications:
•
FIPS 151-1
•
POSIX (IEEE Std. 1003.1-1988)
•
XPG3 BASE branding
•
XTI
•
AT&T System V Interface Definition (SVID) Issue 2 (Base
System and Kernel Extensions)
DEC OSF/1 AXP
Architecture
The DEC OSF/1 AXP operating system is an advanced kernel
architecture based on Carnegie Mellon University’s Mach
V2.5 kernel design with components from Berkeley Software
Distribution 4.3 (BSD) and other sources. DEC OSF/1 AXP
provides numerous features to assist application programmers
in developing applications that use shared libraries, multithread
support, and memory mapped files.
To ensure a high level of binary compatibility with the ULTRIX
operating system, the DEC OSF/1 AXP operating system is
compatible with the Berkeley 4.3 programming interfaces.
You May Have
Factory-Installed
Software
If there is a yellow sticker over the system power connector on
your DEC 3000 Model 800/800S/900 AXP system, the operating
system is factory-installed on an internal fixed disk drive, and
you can start it on your system using either the OpenVMS AXP
Factory Installed Software (FIS) procedure, or the DEC OSF/1
AXP Factory-Installed Software (FIS) Startup Procedure.
Chapter 6 describes how to start your system if it has a
factory-installed operating system.
