Nehalem-EX. The operating systems that
have this support continues to operate
normally.
The operating systems don‘t support
Nehalem-EX SW recoverable error will halt
w
ith Machine Check Exception.
If configured to NMI instead, the system
halts with a NMI message.
*
The Correctable Error logging threshold is configurable and based on a setup question.
†
This SEL entry inherently implies that the correctable error logging threshold has been reached.

If configured to do so, the BIOS may generate an NMI instead
