Dipmi.rst2 The Linux IPMI Driver
7 The Intelligent Platform Management Interface, or IPMI, is a
12 standardized database for field-replaceable units (FRUs) and a watchdog
15 To use this, you need an interface to an IPMI controller in your
17 management software that can use the IPMI system.
19 This document describes how to use the IPMI driver for Linux. If you
20 are not familiar with IPMI itself, see the web site at
21 https://www.intel.com/design/servers/ipmi/index.htm. IPMI is a big
