Well i would love to see them try this mod on a set of dual celmines and see if they acctually work. My opinion on the cAo stepping with smp disabled is that maybe thoughs were the test bed for disableing the celmines. Possibly they werent meant to be relieased intel has pulled this kind of bonner before. Remember the mobile pentium2's with the pentium3 id number in them that got put into pentium2 notebooks by mistake and no one found out about them till the whole stink went up about the pentium3 chip id and intel ended up doing a dance over that one. Finally releasing a proggy to disable the id at bootup? This could have been the same or similar situation. I wouldnt be really surprised if this turned out to be the case and the celmines did do smp with this mod.
I haven't seen anywhere else on the web regarding the modification of the MS-6905 Master CPU converter card to run dual Pentium III coppermine FC-PGA cpus on dual cpu motherboards. Where else did you see this information posted? It's difficult to believe that your modification would work. I would like to see more proof.

I did dual FCPGA coppermine 500s @666 on a P2B-DS a few weeks ago with this mod using the old stepping, cA2.Also, the dual enabling pin is not M33 or N33 but X2(BR1). The reason I think the mods work is that the slockets have the coppermine circuits and they are enabled by jumpers, just no voltage to X2. The mods provide the necessary voltage so B75 on the cardedge is detected by the chipset.

Thanks Peter for the link!
I surfed over there and found the discussion interesting. Except for one thing. Does the mod work for both the new FC-PPGA Celerons and the FC-PPGA Pentium III's? Are they both electronically similar so that the MS-6905 Master slotkey modification will work on both?

which links to the earliest known English N33 discussion.
As far as I know, noone has gotten dual Celeron IIs working yet.
The optimists say it is possible.
The pesimists say it is not.
According to Intel specification sheets, the pin-out of the Celeron II seems to be similar to the Celeron, not the Pentium III.
One thing that seems to prevent the Celeron II from working in an old Celeron motherboard is that V_cmos has been reduced from 2.5 v to 1.5 v.
Perhaps after I get the P3 working, I'll look at the C2.

I was checking out the N33 to pin3 J3 jumper mod. I am assuming you don't need to cut off any pins from the CPU right? I hope not. Also I was thinking of installing a small single dip switch for the N33 to pin3 J3 jumper, just in case the PIII B-0 stepping doesn't require it.
