Bitfields for Intel 82443BX DRAM Read/Write Thermal Throttling Control:
Bit(s)	Description	)
 63	lock all read and write throttle control register bits (exists in Write
	  Throttling control register only)
 62-46	reserved
 45-38	global DRAM sampling window (in four-millisecond units)
 37-26	global QWORD threshold (documented as units of 215, but may be typo and
	  actually be units of 2^15 = 32768)
	thermal throttling will be invoked if the number of QWORD accesses
	  during the sampling window exceeds the threshold count
 25-20	throttle time in multiples of the sampling window
 19-13	throttle monitoring window in 16 DRAM-clock units
 12-3	throttle QWORD maximum count -- while throttling is enabled, at most
	  this many QWORD accesses are permitted during each throttle
	  monitoring window
 2-0	DRAM Throttle Mode
	100 normal operation
	else Intel Reserved
