+  message: <<EOM
+This port includes an RC script, which is one of two methods to update the
+CPU microcode on a FreeBSD system.
+
+1. The first method, which does not require the RC script included in this
+   port is currently only supported on FreeBSD 12.0 or later and Intel i386
+   and amd64 processors.  It is the preferred method when available because
+   it ensures that any CPU features introduced by a microcode update are
+   visible to the kernel by applying the update before the kernel performs
+   CPU feature detection.
+
+   To enable updates using the first method, add the following lines to
+   /boot/loader.conf:
+
+   cpu_microcode_load="YES"
+   cpu_microcode_name="/boot/firmware/intel-ucode.bin"
+
+   The microcode update will be loaded when the system is rebooted.
+
+
+2. The second method, which uses the RC script included in this port can
+   be enabled by adding the following line to /etc/rc.conf:
+
+   microcode_update_enable="YES"
+
+   The microcode update is then applied upon reboot or when the microcode
+   update service is run via:
+
+   # service microcode_update start
+
+   If the CPU requires a microcode update, a console message such as the
+   following will appear:
+
+   Updating CPU Microcode...
+   %%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl0 from rev 0x17 to rev 0x22... done.
+   %%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl2 from rev 0x17 to rev 0x22... done.
+   %%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl4 from rev 0x17 to rev 0x22... done.
+   %%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl6 from rev 0x17 to rev 0x22... done.
+   Done.
+
+It is safe to enable both methods.
