then set it back to the default position.
3. Connect the system's power and then start the
system.

CPU Bus Frequency (JP2A/JP2B)
This jumper allows the CPU bus frequency to be
determined either by the CPU or the user. Set both
jumper cups to pin 1-2 (default) if you are not sure
what frequency your CPU support.
PS/2 Keyboard Power On Function (JP5)
This board is able to be turned on by the keyboard.
To use this function, enable the Power On Function
option in BIOS's Integrated Peripherals screen
(See section 3-8). You must also set this jumper's
cap to pins 2-3 to use this function. Some out-
of-date keyboards may require larger current than
supplied by the Suspend 5V of modern power
supplies. When using older keyboards disable
this function.
