comp.sys.hp.hpux FAQ (Frequently Asked Questions)
Subject: 1. INTRODUCTION
This article contains the answers to Frequently Asked Questions (FAQ) seen
in the Usenet newsgroup comp.sys.hp.hpux. Issues may also be discussed in
comp.sys.hp.apps, comp.sys.hp.misc, and comp.sys.hp.hardware. Discussion
in this document centers around Hewlett-Packard computer systems running
the HP-UX[R] operating system; the focus is on HP-UX 10.20, and later,
running on HP9000 Series 700 workstations and HP9000 Series 800 servers,
though some of the information presented may also apply to earlier
versions of HP-UX, including HP-UX for Series 300, 400, 500, and 600
HP9000 machines. Previous versions of this FAQ contained some information
specific to HP-UX 9.x and earlier; such information has been removed, as
of version 11.11.0105 of the FAQ. This decision was made because HP-UX
versions 10.00 and earlier have been officially classified as obsolete by
HP, as well as to permit greater focus on the more current versions of
HP-UX. The FAQ will be updated every other month or as the maintainer
sees fit, and it will be posted on Usenet once a month.
