== Voltage Control ==
''This section is presented for reference, coreboot currently ignores this chip, leaving the hardware-default memory voltage at 2.55v and the CK804 at 1.50v.''
The MS-6 chip appears at address 0x2f (or 0x5e if you consider the
R/W bit part of the address) on the secondary SMBus.
The chip is accessed by writing its IC address, followed by writing
a register index, and then reading or writing a data byte.
