Introduction

This book is an informational guide to Hewlett-Packard PA-RISC and IA64 computer systems, archi-

tecture and operating systems. PA-RISC is a computer architecture developed by Hewlett-Packard in

the early to mid-1980s and used in a long range of HP technical workstations and servers (the vari-

ous “HP 9000s” ). Some systems based on HP/Intel Itanium IA64 are also covered as descendants of

the HP 9000/PA-RISC systems.

This book, now in its second edition, is the offspring of the online project OpenPA.net, a non-commer-

cial, central information resource on PA-RISC computers and technical details. It is independent of

The Hewlett Packard Company. The online OpenPA.net is a registered serial publication with the ISSN

1866-2757.

Plans for an ofﬂine-viewable edition of OpenPA.net for printing-out were ﬁrst discussed in 2002 but

quickly abandoned for lack of technical feasibility and knowledge. A second attempt in 2006 led to

the First Edition, published in Summer 2006 and completely updated in November 2007 with Release

1.1 of the First Edition. A limited numbered edition was printed and bound in December of that year,

the Release 1.2. Much polishing, content additions (about 90 pages) and updates led to the greatly

improved Second Edition in May 2008, quickly followed by 2.1 in October 2008 with more content.

Updates included an improved typeset, much polished T

X usage and much work devoted to tweaking

details. More reformatting, several page removals and text overhaul resulted in the Second Edition

2.2 in Winter 2008/2009. The process from the online HTML sources to this PDF is rather long and

complicated, with the bulk of the work automated by helper scripts and programs. The only handrolled

parts are this introductory chapter, the title/preface pages, the main T

X ﬁle and several manually for-

matted tables.

The online cousin of this book, OpenPA.net, was founded in 1999 after the author got his ﬁrst PA-

RISC workstation and found almost no coherent information on it and HP PA-RISC on the internet.

This bothered him a lot, since other popular Unix/RISC workstation families were thouroughly and

well documented (as for example Sun SPARC, DEC MIPS and Alpha). Moreover, at that time many

old HP 9000 systems were phased out in favor of new Unix or Windows NT servers resulting in the

availability of a lot of used and quite fast PA-RISC computers on the market. The author then spent

a lot of time digging through various webpages and the USENET looking for documentation on these

systems. After having gathered a considerable amount of information, documentation and references

he ﬁnally decided to compile this to a webpage and make it publically available, with the ﬁrst version

of the online pages hosted by Bill Bradford of SunHELP. Over the years more PA-RISC computers

fell into his hands and he explored other available operating systems, resulting in more details on the

site. The support from HP for the PA-RISC Linux project made more interesting documents about PA-

RISC internals available. Furthermore, other open-source operating systems for PA-RISC computers

made signiﬁcant progress (primarily OpenBSD/hppa from Michael Shalayeff) so these computers were
