Model 744 Board Computer Overview
Operating System Overview
Operating System Overview
The Model 744 can be used with either of two operating systems, HP-UX or
HP-RT. This manual provides basic information you will need for booting
and running HP-UX. It also provides some overview information for HP-RT.
The Model 744 uses the standard HP-UX 10.20 or later operating system, a
highly versatile system for multitasking, running your application programs,
and performing a variety of development tasks. Refer to HP-UX System
Administration Tasks for detailed installation and operation procedures for
HP-UX.
The Model 744rt uses HP-RT 2.21 or later, a real-time operating system.
HP-RT is HP’s real-time operating system for PA-RISC VME board com-
puters. It is a runtime-oriented product based on industry-standard applica-
tion programming interfaces. HP-RT is designed around the real-time
system principles of determinism (predictable behavior), responsiveness,
user control, and reliability for “mission-critical” applications.
Refer to HP-RT System Administration Tasks for detailed installation and
operation procedures for HP-RT.
The HP-RT development environment consists of the following:
• An HP-UX host system (for example, a Model 748i), running the sup-
ported HP-UX operating system, with CDE, X Window System, or HP
VUE installed.
• DDS-format tape drive or CD ROM for loading HP-RT on the host
system.
• The HP-RT target system (such as a Model 744rt).
