When jumper setting Auto it only can support CPU/SDRAM frequency at 66/100,
100/100, 133/100 MHz, we recommend setting 133/133 manually when use F.S.B.
133MHz CPU to increase performance.
In “Miscellaneous Control” section of CMOS Setup Utility, you can increase the CPU
clock step by step increase for over clocking possibility. Please refer to page 11 for more
details.
(2) Keyboard Power On Function setting (3-pin) : JK1
