see Section 10.1, “Overview”.
5.3.6
Unit-Level Errors from the NSI
The IMCH hardware captures error events from the NSI interface that connects the
IMCH to the IICH in the NSI_FERR and NSI_NERR registers. The NSI interface reports
an error event to the IA-32 core through IA SCI, SMI, SERR, or MCERR signals based
on the settings in the NSI_SCICMD, NSI_SMICMD, NSI_SERRCMD, and
NSI_MCERRCMD registers. Software can independently configure the specific signal
that each buffer unit error event uses.
.
Table 5-6.
Table 5-6 summarizes the error conditions that the NSI can generate.
