Some Socket 7 boards allowing using FSB or multiplier jumpers' pins as Turbo button pins. So the button can be connected instead of those jumpers and it will work.
I don`t see how to connect it...
Connect to FS0...FS2 or BF0...BF2. Depending on what you want to change on fly and the jumper position table. Some MMX CPUs have locked multipler, so can't be over-/down-clocked via it, only FSB clock can be used with them. But some have it unlocked, so an overclocking is possible for them.
Unlocked MMX-200 processors can work from 133 to 233-250 MHz clocks. Locked ones have less clocks, 200-225MHz on most of i430TX boards.
