* Actual requirements will vary based on your system
configuration, and the applications and features you
choose to install.
Processor performance is dependent upon not only the
clock frequency of the processor, but the number of
cores and the size of the processor cache.
Disk space requirements for the system partition are
approximate. Itanium-based and x64-based operating
systems will vary from these disk size estimates.
Additional available hard disk space may be required
if you are installing over a network.
