A7N8X external CPU clock jumper

I got a question about this board and the Jumper that switches it from 166 external CPU clock to 200. Does this jumper have to be switch to the 200 side to obtain the CPU 200mhz external clock speed ? ]

I have mine set up in bios so it loads and starts that way(200 external clock) but if i switch the jumper it wont boot that way!

If you check the manual for the A7N8X, pins 1 and 2 set the FSB to run @ 400/333/266, 2 and 3 set at 200 fixed.

This is the deluxe 2.0 version of the board anyways

Cool Thanks !
