Both Boxboro and ICH have an IOxAPIC, and both are used for the PCI devices underneath
Boxboro. The ICH’s IOxAPIC range begins at 0xFEC00000, and Boxboro’s begins at
0xFEC40000.

Hides unused devices from the OS by setting the appropriate ICH registers.
Customer messaging policy
•
See the SEL for any action from low level I/O subsystem faults, because the System Insight
Display may not have any illuminated LEDs.
•
For configuration-type errors, for example, no iLO 3 MP or core I/O HBAs installed or working,
see
“Supported configurations” (page 75)
for actions.
•
Some diagnostic messages are reported for high level I/O subsystem errors. All fatal I/O
subsystem errors cause global MCAs.
