NAME

     mptable -- display MP configuration table

SYNOPSIS

     mptable [-dmesg] [-verbose] [-grope] [-help]

DESCRIPTION

     The mptable command finds and analyzes the MP configuration table on an Intel(tm) MP spec capable motherboard.  It is useful for debugging an
     SMP kernel that will not boot, as well as examining the configuration of a system.  It can be run with a UniProcessor kernel.

     It must be run with gid kmem privileges.

     The following options are available:

     -dmesg  Include a dmesg dump.

     -grope  Look in areas it should not NEED to, use ONLY as a last resort.

     -help   Print a usage message and exits.

     -verbose
	     Print extra info.

SEE ALSO

     smp(4), dmesg(8)

HISTORY

     The mptable command first appeared in FreeBSD 3.0.

CRASHINFO(8)						    BSD System Manager's Manual 					      CRASHINFO(8)

NAME

     crashinfo -- analyze a core dump of the operating system

SYNOPSIS

     crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]

DESCRIPTION

     The crashinfo utility analyzes a core dump saved by savecore(8).  It generates a text file containing the analysis in the same directory as
     the core dump.  For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.

     By default, crashinfo analyzes the most recent core dump in the core dump directory.  A specific core dump may be specified via either the
     core or dumpnr arguments.	Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel
     that generated the core.  It then looks for a matching kernel file under each of the subdirectories in /boot.  The location of the kernel
     file can also be explicitly provided via the kernel argument.

     Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8),
     ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).

     The options are as follows:

     -d crashdir
	     Specify an alternate core dump directory.	The default crash dump directory is /var/crash.

     -n dumpnr
	     Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory.

     -k kernel
	     Specify an explicit kernel file.

     textdump(4), savecore(8)

HISTORY

     The crashinfo utility appeared in FreeBSD 6.4.
