+          Machine Check support allows the processor to notify the
+          kernel if it detects a problem (e.g. overheating, data corruption).
           The action the kernel takes depends on the severity of the problem,
-          ranging from a warning message on the console, to halting the machine.
-          Your processor must be a Pentium or newer to support this - check the
-          flags in /proc/cpuinfo for mce.  Note that some older Pentium systems
-          have a design flaw which leads to false MCE events - hence MCE is
-          disabled on all P5 processors, unless explicitly enabled with "mce"
-          as a boot argument.  Similarly, if MCE is built in and creates a
-          problem on some new non-standard machine, you can boot with "nomce"
-          to disable it.  MCE support simply ignores non-MCE processors like
-          the 386 and 486, so nearly everyone can say Y here.
