What Our Customers Achieve
“Varco was able to meet very aggressive time-tomarket deadlines using MontaVista Linux.
MontaVista’s superb technical support helped our
engineers overcome technical and reliability
challenges”
-- George Boyadjieff
Chairman and CEO
Varco International
VARCO e-drill – Can remotely monitor and analyze oil drilling rig performance in
real-time, detect system problems and enhance operating efficiency, change

MontaVista Sftware Confidential
What Our Customers Achieve
“By using MontaVista Linux, we have been
able to reduce our development time by
one third, compared to traditional
embedded OSes and because Linux is so
flexible and easy to customize, we can
provide our customers with specialized
products that meet their individual needs.”
-- Kaichiro Takeda
President
Nexterm, Inc.
MontaVista Sftware Confidential
What Our Customers Achieve
“Replacing proprietary software with Linux in our
embedded platform was an old dream.
MontaVista Linux and MontaVista’s professional
services allowed us to finally move forward with
the project, with confidence, and introduce our
new product in less than five months – record
time!”
-- Daniel Dalarossa
CEO
Cyclades
MontaVista Sftware Confidential
What Our Customers Achieve
“MontaVista was the only company driving fully functional
embedded Linux product solutions for our applications. We
were delighted by the performance improvement that
MontaVista Linux delivered in our benchmark tests,
compared with proprietary [Mentor Graphic’s] VRTX and
[WindRiver’s] pSOS real time operating systems that ran on
our previous generation Ethernet switches.
We achieved between a five-fold and ten-fold improvement
in TCP/IP throughput, due primarily to the collective
contribution from the Open Source Community utilized in
MontaVista Linux.”
-- Bruno Rolland
Managing Director
Interface Concepts
MontaVista Sftware Confidential
What Our Customers Achieve
“MontaVista has worked with ITT to pioneer the
port of Linux to the StrongArm processor. No
other vendor was willing to accept the StrongArm
port, but working with MontaVista, we had
MontaVista Linux up and running on our
processor in the first week….
By leveraging MontaVista’s embedded Linux
expertise, our team was able to concentrate on
our technology competence, and bring this
product to market much sooner!”
