SROM Initialization Enable Header (J17)
A 3-pin planar header enables/disables the GT-64260B SROM
initialization. No jumper or a jumper across pins 1-2 enables the
GT-64260B device initialization via I2C SROM while a jumper across
pins 2-3 disables this initialization sequence.
PowerPC Bus Mode Select Header (J19)
A 3-pin planar header selects the processor bus operating mode. No jumper
or a jumper across pins 1-2 selects the 60x bus mode while a jumper across
pins 2-3 selects the MPX bus mode.
