Error Handling
Bad Data Containment: Memory locations with corrupted data can be tagged (sometimes called “data
poisoning”). This limits the impact to the currently running program and greatly reduces the need to reset
the system.
• •
Advanced Machine Check Architecture: Standards-based interfaces enable coordinated error handling
with appropriate escalations and communications among the hardware, rmware and operating system.

a
Integrated capability. May be supported by one or more server vendors in future Itanium®-based systems.
b
Feature was supported by one or more system vendors using proprietary hardware, rmware and/or software components. Vendors may continue to leverage their proprietary solutions or may take advantage of the hard-
ware and rmware support integrated into the Intel® Itanium® processor 9300 series.
c
Integrated capability, but requires additional support from rmware and/or the operating system. System and OS vendors may or may not take advantage of the integrated support.
The features indicated have been validated by Intel to the extent possible. It is up to server manufacturers to validate and conrm full functionality in a complete platform environment.
