Hi folks!
Got here zenith data systems z-station EL with pentium 166 onboard now, i want to upgrade cpu to 200MMX or 233MMX. Got them already. This desktop supports it.
My question is how to set up correct voltage for mmx cpu - it has dual voltage, while installed p166 is single voltage.
Board has only this table:

Is jumper JIF2(B) (on the right) maybe a voltage selector for dual/single voltage cpu? Currently is 4-5 with pentium-s 166.
Manual doesn't describe this jumper set at all.

If i am wrong correct me.
