I suspect that you have configured that motherboard for a Pentium processor instead of for a Celeron processor. Celerons have less Cache memory than Pentiums, and that's most likely why you are getting the error message.
Work through the motherboard manual and the processor specifications again, and ensure you have it configured correctly.
Start off, though, by resetting CMOS. Remove the CMOS battery, and wait at least a few minutes before replacing it. That should clear the CMOS memory, and reset it to default settings. See if it POSTS correctly.
Were you told that the motherboard and processor combination was previously working? It sounds like you have a 'Slot Adapter' for that processor, and not all Slot 1 motherboards were capable of operating correctly with them installed.
