Sorry. I missed the word “typically” in the WHEA documentation. Your
thoughts would still be appreciated.

JAKE (ET. AL.):
I’ve only been periodically following, and really don’t know much
about
the issue, but, just out of curiosity, I was wondering if MCA would at
least partially address this problem. In any case, while checking out
the WHEA documentation, I noticed in the overview, it states:
Note[:] The system management interrupt (SMI) is typically handled by
the firmware, not by the operating system.
I don’t particularly care about the MCA question, but I have an
interest in the statement about SMI. Is this necessarily true
(assuming, of course, no third party participation)? That is, is it
the
case that Windows (or bootmgr or winload, for that matter) does not
install an SMI handler under any circumstance. I understand the SMM
architecture and why it is normally inaccessible and so forth, but I
am
curious as to whether or not Windows has any involvement in the SMI,
particularly as some ICH’s (like the 6300ESB)seem to have provided the
capability to latch or trigger the SMI to everything but the kitched
sink, and mention OS callbacks?
Thanks,
mm

Jake,
This is exciting news - WHEA and LH server… unfortunately the NMI
strikes today, and we’re talking about WinXP 
The PCI config space of the device has the error status information.
So the question is, will the OS or PCI driver reset my device before
my
bugcheck hook can read the device config. space?
Another question - how to read the config space in bugcheck
context…
Thanks,
Pavel
