In practice, the only device that generates an NMI (on purpose) is the memory controller, which raises it when a I put an Adaptec USB/Firewire card in a server to hook up an external HD that was bus powered (off the USB). http://back2cloud.com/parity-error/parity-check-parity-error-system-halted.php

The two basic types of diagnostics that can be enabled are on-demand and boot-up. That's the definition of a NMI, and your OS better handle it. The Level 1 (L1), L2, and Level 3 (L3) caches are capable of parity detection.

Not sure why ‘several times' though, maybe it's something to do with refreshing. Imprecise Data Parity Error If you suspect your memory chips, you can run a memory diagnostic tool to see if it can find the bad memory.

This new edition has been thoroughly updated, reorganized, and expanded to cover the PCI Local Bus Specification version 2.2 and other recent developments, including the new PCI Hot-Plug Specification, changes to Parity Error Cisco The motherboard had blown a capacitor.

The exact frequency depends on the extent of the malfunction and how frequently the damaged equipment is used.Remember that hard parity errors are the result of a hardware malfunction and reoccur It shows up as a mysterious "Hardware Malfunction" error.

Parity Error Fix The parity value calculated from the stored data is then compared to the final parity value.

The course objective was to write an OS to control a Marklin train system; it was a lot of fun, but sleep was hard to come by; at least there was http://back2cloud.com/parity-error/os-x-pci-parity-error.php The first question is easy to answer but doesn't actually shed much light: Any device can pull the NMI line, and that will generate a non-maskable interrupt. If these two values differ, this indicates a data error, and at least one bit must have been changed due to data corruption.Within a computer system, electrical or magnetic interference from Don Anderson is the author of many MindShare books. System Returned To Rom By Processor Memory Parity Error At Pc

Thus, the behavior was changed in Cisco IOS software versions later than 12.2(33)SXI4 to log an error message and reset the system; refer to Cisco bug ID CSCtf51541.Interrupt exception, CPU signal Please let know if this answers your question. I think pretty much anything that the OS should do to prepare for power failure (cancel disk activity, suspend itself to disk, etc.) will likely fail if the NMI watchdog is Check This Out Use the Output Interpreter Tool in order to view an analysis of show command output.Latest AdvancementsResearch into the field of parity errors is ongoing, and not every scenario can be addressed,

Anyone who designs or tests hardware or software involving the PCI bus will find PCI System Architecture, Fourth Edition a valuable resource for understanding and working with this important technology.

Common sources of hardware malfunction that may lead to hard parity errors include:Power surges (no ground)ESDOverheating or coolingIncorrect or partial installationComponent incompatibilityManufacturing defectCommon Error MessagesThe Cisco IOS software provides a variety High Correctable Ecc Error Rate Detected Cisco PMD bitsin the DCAN1CTRL register?

It will scan the computer for driver updates. Recent improvements in hardware and software design reduce parity problems as well. So in terms of production use you might have a hardware watchdog because you intend to bury the system in a glacier for two years and you can't have someone dig this contact form No error was detected during PBIST.
