Should be more like:

	epb=		[X86] Control IA32_ENERGY_PERF_BIAS setting
			Format: { disable | <0...15> }
			"disable" - Kernel will not modify this MSR
			<0..15> - Kernel will set this MSR to i/p static value


But what is "i/p"?  Use whatever word it should be, please.
What do the values mean?
And what does IA32 have to do with this?  does it not apply to x86_64?

thanks,
