Notes
Due to a hardware problem P5A Rev 1.05 and 1.06 will work extremely slow with a K6plus CPU. this has been noticed both with rev E and rev G of the chipset.
The 3.3V supply is not routed the the PCI slots preventing certain cards from powering up.
On Rev 1.06 (and possibly 1.05) boards that have the HIP6004B core voltage regulator can only go down to 2.1V core voltage making the 2.0V setting output 0V instead, boards that have the HIP6004 don't have this problem.
It is possible to swap the voltage regulator with the older non B revision if the lower core voltage is needed.
