13	  Setting this makes the Legacy 8254 Timer available by disabling
14	  clock gating. This needs to be enabled in order to boot a legacy
15	  BIOS or OS not supporting other timers like PM timer or TSC.

17	  While SeaBIOS does not require this timer anymore, it is needed
18	  when OpRoms are being used.
