MontaVista Inserts PICMG Hot Swap into Open Source
Call to Action for CompactPCI Board and Systems Vendors and
Open Source Developers to Support Embedded Linux

Sunnyvale, Calif., April 10, 2001 - MontaVista Software Inc., the company
powering the embedded revolution, today announced the submission of its hot
swap infrastructure code to the Open Source Community.  MontaVista is
releasing the hot swap code as a project on Source Forge
(www.sourceforge.com) with two goals:  to encourage a wide adoption of the
base software and to promote the development of the infrastructure for
fault-resilience and high availability.

The PICMG  (PIC Industrial Manufacturers Group) 2.12 software interface
specification describes the process for installing and removing CompactPCI
boards into and from a running system.  The specification includes the
concept of a hot swap infrastructure, a body of software that interfaces
with the underlying operating system to support hot swap. In particular, the
software infrastructure in PICMG 2.12 supports the discovery, configuration,
and management of hot swapped system resources.  The implementation that
MontaVista is placing into Open Source builds on the Linux 2.4 kernel, and
includes platform drivers for the Ziatech ZT5550 hot swap redundant system
slot board and the Motorola Computer Group 82xx high availability platforms.

³By placing this technology into Open Source, we invite our open software
peers to join forces with us and with industry-leading hardware vendors to
implement PICMG standard technology on the broadest possible platform base,²
commented Kevin Morgan, MontaVista vice president of engineering.  ³Opening
this project on SourceForge is a call to action to all interested parties to
bring this key high availability technology rapidly into the marketplace and
out into deployed systems.²

In keeping with MontaVista and Open Source practices, all pertinent work is
submitted back to the relevant source trees promoting the architecture and
specification for the entire community. MontaVista and others are promoting
PICMG 2.12 and related standards for the above-mentioned platforms and other
carrier class hardware from Motorola Computer Group, Ziatech, Force
Computers, Radisys, and others. Acceptance of standards like PICMG 2.12 will
enhance the infrastructure mix needed by communications equipment
manufacturers to build central office switching equipment, ISP/ASP
platforms, and other networking applications, giving them and integrators
more design options to speed OEM communications solutions to market.

Interested parties can examine and download the project code from
SourceForge at http://sourceforge.net/projects/picmg212-hs  -- for
additional information on the hot swap, redundant system slot, and chassis
drivers for embedded Linux, contact MontaVista Software.

High Availability (HA) is a term for technology that enhances the ³up-time²
of computer systems by distributing functionality across multiple CPUs.   In
response to hardware and software failures, HA systems facilitate the rapid
transfer of control (fail-over) from a faulty CPU, peripheral, or software
component to a functional one, while preserving operations or transactions
in progress at the time of failure.  Many embedded designers choose the
standard CompactPCI board and system form factor for HA designs since it
supports hot swap (replacement and insertion) of system and peripheral cards
without the need for cycling power, reducing technician-assisted
