Note: If NMIs are enabled, and parity error checking on PCI is also enabled, then parity errors will cause
Parity Error Detection
The ICH4 can detect and report different parity errors in the system. The ICH4 can be programmed
to cause an NMI (or SMI# if NMI is routed to SMI#) based on detecting a parity error. The

an NMI. Some operating systems will not attempt to recover from this NMI, since it considers the
detection of a PCI error to be a catastrophic event.
