Help with jumper settings on MS-6905 master slotkey

[worm]

I just purchased a MSI MS-6905 master slotket, and have the key to the jumper settings, but I am still confused. I have a Celeron 600 and a AOpen AX6BC. I wanted to start with default which I thought would be the following.

J1(1-2) J4(1-2) = User defined
J3(1-2) = Coppermine 256
JVX(1-2) = Auto voltage.

The system would not boot so I changed to J3(open) and the machine booted. I would have thought that this was the setting for an old Celeron or PIII and not Celeron 2 or PIII Coppermine, anyway it is working.

I also wanted to overclock, so I set
J1(1-2) J4(1-2) = 100Mhz

No go again, so I set it back, and set the bus speed in the BIOS, so I am running at 900Mhz, but I really would like to be able to understand the jumper settings.

I would appreciate information on how others have their jumpers set or any other information.

Thanks

I just checked the MSI site and in their manual J3 is 1-4 compared to mine 1-3?

That seems odd, I had a celeron 566 that I overclocked to 850, and I set it up pretty much the same way as you did originally, but I didn't use auto voltage. I manually set the voltage to 1.65(I know it's 1.5 default, but I was overclocking). I covered J1, covered 1-2 on J4, and covered 1-2 on J3, because it is technically a Coppermine. I bought my Celeron and slotket from Compuwiz here on the forum, and that's how it came. He knows how to set it up, and it worked so I never thought much of it. What motherboard do you use?

I don't think the jumpers matter much - maybe except the coppermine one. All those voltages and fsb are just what the slotket asks from your motherboard. You don't get 1.65V unless your motherboard can give 1.65V, and you permit your MB to do so.
