Sure.
Leave all the jumpers on your slotket set to auto, make sure the jumper that selects the kind of CPU is set for the celeron not for the PIII(Copermine).
Since you are using the latest bios already, just drop the slotket in with cpu and cooler on, and boot. Go directly into the bios, make sure voltage is correct (1.7v). Turn off speed hold error, change AGP divider to 2/3 (AGP/CLK).
2/3 = 2x's mode
1/1 = 1x's mode

You should be able to change your fsb directly to 100, and boot. My bro just got the 600 cC0, same setup as mine and yours,, booted right to 900 default voltage. He is up to 928 now @ 1.75v. He has not tried to go higher, but it should no prob.
If you need further settings, reply back and I can give them to you. Also, if you are having probs, list your entire system specs pls.
Dohhh!!!
