RE: Reference code B90037F0

For this Reference code the book says:

Service Problem Analysis Procedures:

For this problem analysis procedure, do the following:

For more information than what was shown in the SRC data on the 
operator panel, look in the start OS/400 data object.  The start OS/400 
data object can be located by displaying the MI object, QWCSCPF, which 
has a type of 19 and a subtype of DE.  The object is located in the QSYS 
library.

The start OS/400 data object contains the termination data until the 
operating system is initiated by VLIC on the next IPL.  Once the operating 
system is initiated, the start OS/400 data object is cleared of the 
information from the prior IPL or system termination.  The object and the 
information therein should be accessible on the next IPL after storage 
management recovery has been run and before the operating system is 
initiated.  Using the Dedicated Service Tools (DST), select the step mode 
of IPL to stop the IPL at the proper point.

For a visual layout of the start OS/400 data object,  I can email you 
TIFF scanned images of the pages if you like.
