Setting CPU Type (J20)
Pin block J20 selects the CPU type. Since this also affects the power
supply to the CPU, it is important to be very careful with this setting,
to avoid damage to the CPU.
For P55C, K6, and M2
type CPUs, set jumper caps on the two pin-
pairs which are closest to the center of the motherboard.
For P54C, K5, and M1
type CPUs, set jumper caps on the two pin-
pairs which are closest to the edge of the motherboard.
