Mission Critical Linux, Inc. and Marvell(NASDAQ:MRVL) Announce Availability
of Linux Evaluation Platform for High-Performance System Controller for
PowerPC Based Systems

--Port of Marvell's DiscoveryTM GT- 64260 Evaluation Platform to Linux
expands capabilities of industry-leading system controller and will speed
development of next-generation communications products--

Lowell, Massachusetts - July 9, 2001 - Mission Critical Linux, Inc., the
industry leading Linux solutions and services company, and Marvell, a
technology leader in the development of extreme broadband communications
solutions, today announced that they have developed a Linux-based evaluation
kit for the Marvell DiscoveryTM GT-64260 system controller.
Working together, Mission Critical Linux and Marvell developed the evaluation
kit.  Customers now have the system-level development platform necessary
to evaluate and develop Linux-based solutions for the Marvell Discovery
GT-64260 chipset running in PowerPC-based systems.  It is anticipated
that this will significantly decrease the time necessary to develop
Linux-based, next-generation communication systems that want to take
advantage of the GT-64260.
"The development of Linux boot and runtime support for our Discovery GT-64260
development platform will make it easier for data communications and
telecommunications equipment manufacturers to see what our chips can do in
a Linux environment," said Dave Matteucci, Marvell's Vice President of the
Internetworking Products Business Unit.  "This will only enhance the
advantages we bring to our customers in terms of integration, flexibility
and time-to-market."

Marvell's Discovery GT - 64260 is a full-featured system controller that
combines high-performance system and communications peripherals on a single
chip.  Supporting industry standard PowerPC processors like the Motorola
74xx and 75x families and IBM's 750 series CPUs,  the GT- 64260 System
Controller includes three ethernet controllers, two 64-bit PCI busses, and
two multi-purpose serial controllers (MPSC).  This announcement means that
Linux boot and runtime support is now available to OEMs needing to take
advantage of the Marvell Discovery Series Chips.
"Our work with Marvell is another example of how Mission Critical Linux's
expertise in Linux can help companies develop solutions and technologies
that take advantage of the open-source operating system," said Brian Stevens,
Chief Technology Officer of Mission Critical Linux. "It was nice to be
able to work with a company like Marvell and bring the advantages of Linux
to those looking to take advantage of Marvell's next-generation Discovery
GT- 64260  platform."
