 .SH SMI COUNTING EXAMPLE
 On Intel Nehalem and newer processors, MSR 0x34 is a System Management Mode Interrupt (SMI) counter.
-Using the -m option, you can display how many SMIs have fired since reset, or if there
-are SMIs during the measurement interval, you can display the delta using the -d option.
+This counter is shown by default under the "SMI" column.
