That page says JP35 is bus speed, so that should be set to 66 Mhz (Pins 1 & 2, 3 & 4 closed), and then you need to figure out what cpu multiplier does down there below that. The Pentium 200 MMX is 66 Mhz with a 3x multiplier, but the description for your motherboard has weird definitions for the multiplier.

If it was me, I would just set the bus speed to 66 Mhz and then try each of the multiplier settings one at a time until it comes up showing 200 Mhz then go with it. It's only 4 settings for the multiplier on that system so it shouldn't involve too much work.

Good luck!

I did try that, but there are certain configurations that just get 0 MHz in the BIOS 😐

I have no experience with this system and am certainly not an expert but here's my thought on it;

I think you can ignore the 'clock speed' column in the CPU MULTIPLIER SELECTION table. Just take the FSB you're running on and then use the numbers in the column 'multiplier'. Divide by the first number and multiply by the second one.

So for a 66MHz FSB and the first row in that table you'd get 66MHz / 1 x 3 = ~200MHz.
For a 166MHz cpu it's probably using the values in the second row because those match.
The third row would give you a 133MHz cpu and the fourth a 100MHz cpu.

If it doesn't work, try those multipliers with the clock speed stated in the second column. If that does work, then there's a chance the system only works with specific cpu's (150MHz, 133MHz & 90MHz). Unless you had that 166MHz cpu working in the system, in which case I'm out of ideas.

Hope this somewhat helps.
