Error Logs 5-21
Fatal Error Halts
Fatal error halts are single errors that occur when the operating system is
running. Only one operating system fatal (OS fatal) error at a time can exist in
flash ROM. When a new OS fatal error occurs, it replaces the old error in the
flash.
Double Error Halts
Double error halts are conditions in which the processing of a fatal error
triggers a second error. Two varieties of double error halt errors can occur,
based on which code is executing when the second error occurs: machine checks
in PALmode or double errors (HAL code). Double error halts can occur on
multiple processors at the same time. As a result, multiple double error halt
logs can be generated at the same time and possibly in concert with another
single fatal or correctable error log.
For both single and double error halts, if the System Error Logging Software for
Alpha kit is installed, the next operating system boot causes the new error
frame to be copied automatically to the Windows NT event log for viewing and
analysis.
NOTE: The System Error Logging Software for Alpha kit is provided on the
platform OEM floppy and with the HAL updates on the World Wide
Web:

The software works with the operating system layer to ensure that
errors and FRU table information are logged in the event log. It also
provides correctable error throttling and user notification for
environmental warnings. In addition, the kit provides an API for
Compaq Analyze to log information to the FRU EEPROMs by means of
the DPR.
