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.

NAME

     dmesg -- display the system message buffer

SYNOPSIS

     dmesg [-ac] [-M core [-N system]]

DESCRIPTION

     The dmesg utility displays the contents of the system message buffer.  If the -M option is not specified, the buffer is read from the cur-
     rently running kernel via the sysctl(3) interface.  Otherwise, the buffer is read from the specified core file, using the name list from the
     specified kernel image (or from the default image).

     The options are as follows:

     -a      Show all data in the message buffer.  This includes any syslog records and /dev/console output.

     -c      Clear the kernel buffer after printing.

     -M      Extract values associated with the name list from the specified core.

     -N      If -M is also specified, extract the name list from the specified system instead of the default, which is the kernel image the system
	     has booted from.

FILES

     /var/run/dmesg.boot  usually a snapshot of the buffer contents taken soon after file systems are mounted at startup time

SEE ALSO

     sysctl(3), syslogd(8)

HISTORY

     The dmesg utility appeared in 4.0BSD.
