   Yes.  Or at least it used to be.  During a crash the system error log 
   is (used to be?) dumped in addition to the contents of memory (even 
   though it probablky is in memory).  During a boot after a crash, it 
   is logged to the system error log in the same format it would have 
   been logged if the system had not crashed.  Many times the errors
   are relavent to the crash.  I don't know if this essentially second 
   copy of the error log has ever changed.

   AUTOGEN will get the size correct if you put the dumpstyle in
   modparams.dat.
