Additional Considerations for Itanium-Based Platforms
Any information or service that is available in Itanium architecture firmware specifications
supercedes any requirement in the common IA-32 and Itanium architecture specifications listed
above. The Itanium architecture firmware specifications (currently the Itanium
®
System
Abstraction Layer Specification and portions of the Intel
®
Itanium
®
Architecture Software
Developer’s Manual, volumes 1–4) define the baseline functionality required for all Itanium
architecture platforms. The major addition that EFI makes to these Itanium architecture firmware
specifications is that it defines a boot infrastructure and a set of services that constitute a common
platform definition for high-volume Itanium architecture–based systems to implement based on the
more generalized Itanium architecture firmware specifications.
The following specifications are the required Intel Itanium architecture specifications for all
Itanium architecture–based platforms:
• Itanium
®
Processor Family System Abstraction Layer Specification
• Intel
®
Itanium
®
Architecture Software Developer’s Manual, volumes 1–4
