What kind of cpu for iwill dbd100 mb

[Guest]

Just put iwill dbd100 in a full tower with 300w ps. Board has 440bx and will support single or dual pII or pIII's. Specs say board supports 66 or 100 fsb. Theres no jumpers on board, award bios supports multipliers up to x8 in .5 increments. I don't see any cpu voltage adjustments, but docs say it will support "any intel published" cpu's up to a pentium III 800 meg. (100 fsb x 8). These are with iwill smart setting, but I can set bios manually too. I have lots of questions about this like:
In docs (bios-manually) I can set fsb 103,112,133 meg?
Would I be able to divide back down for agp and pci?
How would this effect agp and pci if I leave it high if I can't divide agp and pci back down?

What I currently have in mind doing is running a single 800 pIII coppermine and 133 sdram that's 100 compatable, and trying to (bios)manually clock up fsb one step up at a time till I lose stability then back off. But then I read something about with a slocket (which slocket?) can do agp and pci dividing the if bios doesn't support it.
I'd appreciate any input from anyone who is familiar with this. Thanks!
What cpu would be best to put?
Do coppermine pIII's have same core voltages as other pIII's?

The core voltages in the coopermines are actually lower than the PII's because it's manufactured at .18 microns.

OK thanks! I was just reading that coppermines core voltage is 1.65 and celerons is 2.0
Theres an article here that talks about taking a slocket II and modifying the card (originally intended to put a celeron
into a slot I)to hold a coppermine, and the card has voltage jumpers on it where I can lower the voltage to the coppermine to 1.65. I don't yet know where to find the slocket II card but I'll be looking. Right now I'm wondering if I shouldn't just put a straight Pentium III in slot one?
iwill's bios config says it will clock up to 800 meg (100fsb x 8). Maybe I should just play with the 100fsb for now, with 133 sdram running at 100?
Docs say agp is independent of pci bus and is seperately (ac timed)....ac timing for 133 Mhz data transfer rates allowing data throughput of 533 Meg/sec. agp supports 2x mode and "DIME", so now I'm wondering which would be best graphics card to use (most bang for the buck)? any ideas?
Thanks!

MSI makes a slocket that supports the coppermime's (MS6905 v1.1). The 440BX chipset does not have a 1/2 agp divider so anything over 100mhz will run the agp clock out of spec, but depending on the vid card you get this may not be a problem. The geforce2 and mx do not seem to have any problems runing way out of spec ie 89mhz+.

Your not going to get far with PC100 memory. Especially if it's market brand. You can try though. =)

Thanks,
OK 89 Mhz on Agp, ia cool right? But what happens (when I shift fsb to 133) to the PCI bus? I don't know if this iwill mb will divide down to 1/4 so the pci bus will only get 33 Mhz?
I found iwill slocket, (can put coppermine, can set core voltage to 1.65, supports 133 or 100 Mhz.
I read bout 500E coppermine being oc'ed to 750 or 800 meg with no problem.
if I go up to (133 x 5) thats 665 meg, but still wondering
about pci bus?

OK so I'll go with 133 (about 256K to start), I'm still on that divide down to 1/4 for 33meg pci bus though?
