LedCache is yet another StrongArm cache control program. But it's different. You can toggle the Instruction, Data and Write caches seperately. Hit ALT+F9 and you can see which caches are on by looking at the keyboard LEDs. Hit ALT with F10 to F12 to toggle the corresponding LED and cache on and off.
