+         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.
