NMICrashDump

HKLM\SYSTEM\CurrentControlSet\Control\CrashControl

Data type

Range

Default value

REG_DWORD

0 | 1

0

Description

Determines whether the system performs standard software error processing when a hardware error causes a nonmaskable interrupt (NMI).

This entry is used only on computers with x 86 architecture, such as Intel (™) processor platforms. Other systems always perform standard software error processing when hardware interrupts are detected.

By default, an NMI interrupt stops the system and displays a hardware-malfunction message. If the value of this entry is 1, the system also performs standard software error processing. The software error processing displays a Stop ( blue screen ) message containing information about the state of the operating system and of other programs when the NMI interrupt occurred.

If the value of the CrashDumpEnabled entry is also 1, the standard error processing routine writes the contents of system memory to a recovery log file.

Value

Meaning

0

NMI interrupts do not trigger standard software error processing. Only a hardware-malfunction message is displayed.

1

NMI interrupts display a hardware-malfunction message and also trigger standard software error processing, including a Stop ( blue screen ) message.

This entry is designed to suppress the Stop message when a hardware error causes the system to stop. The text display associated with the Stop message might fill the screen and make it difficult to find the hardware malfunction message. Also, some processors cannot process the high volume of error messages associated with an NMI interrupt and a Stop message without error.
