Bits Default
1:0 00b Setting the bit will mask out the ac97 PCI configuration space
(function 5, 6)
2 0b 0-external clock, 1-shared with PCIE 100MHz clock
3 1b 1 – Enable HD AUDIO module

4 0b When set, HD AUDIO data transfer will not cause the
BM_STS bit to be set and to wake up the CPU from C3 state.
This is used when previous version of SB did not have C

function in SB600, this function is not necessary and should
not be enabled if the C-state pop-up/down is enabled.
