Note: Be sure to use the installation tool that comes with your microprocessor
installation tool assembly. The tools are similar in function and design, however
Tool A has one setting for installing one size of microprocessor, and supports the
following families of microprocessors: E5-26xx, E5-46xx. Installation Tool B has two
settings for installing two different sizes of microprocessors. The settings that are
marked on Tool B are "L" for smaller low core microprocessors, and "H" for larger
high core microprocessors. Installation Tool B supports the following families of
microprocessors: E5-26xx, E5-46xx, E5-26xx v2, E5-46xx v2.
Microprocessor Installation Tools A and B are shown in the following illustration.
