The Intel
mobile Pentium
II processor introduces a higher level of performance for today’s mobile
computing environment, including multimedia enhancements, and improved Internet and communications
1
capabilities. It provides an improved performance for applications running on advanced operating systems
such as Windows* 98. On top of its built-in power management capabilities, the Pentium II processor takes
advantage of software designed for Intel’s MMX technology to unleash enhanced color, smoother graphics,
and other multimedia and communications enhancements.
The mobile Pentium II processor may contain design defects or errors know as errata that may cause the
product to deviate from published specifications. Current characterized errata are available upon request.
