AGP_SBSTB#
AGP_ADSTB[1:0]#
Have internal pull-downs.
ST[0] Pull-down to GND 2 kΩ ST[0] signal pulled low indicates that
system memory is DDR SDRAM
ST[2:1] Pull-up to V1.5S 8.2 kΩ It is required that ST[2:1] have site for
external pull-down resistor to ground,
but the resistor should not be
populated.
