✎
A manual Hardware Abstraction Layer (HAL) upgrade is necessary
when installing a second processor
after
the system has gone
through the software unbundling process. If a second processor is
installed prior to unbundling, a manual upgrade is
not
necessary.
HP recommends that the software unbundling process be completed
prior to installing additional components. For information about
upgrading to a multiprocessor HAL, refer to the documentation
included in your processor upgrade kit.
Upgrading a Processor
You can upgrade your workstation by replacing an existing processor
with a faster processor. Before replacing an existing processor, you
will need to purchase the necessary hardware option kit. Please follow
the guidelines and procedures provided in the following sections to

WARNING:
To reduce the risk of personal injury from hot surfaces,

CAUTION:
Installing the processor incorrectly may cause damage to the
system board. Have an HP authorized reseller or service provider install
the processor. If you choose to install it yourself, read all of the instructions
carefully before you begin.

CAUTION:
Static electricity can damage the electronic components of
the workstation. Before beginning these procedures, be sure that you
are discharged of static electricity by briefly touching a grounded
metal object.
