Compaq 5000 series CPU compatability

[twoheadlines]

I would like to upgrade the CPU on an older model Compaq Presario 5000/K series desktop. Currently installed is a 900Mhz Duron. I'm not sure what the model MB is, but presume it to be a micro ATX of some description. Would it be possible to "pop" in an Athlon XP 2.0 and if that is possible would the BIOS need upgrading as well?
Cheers.

Can you be a little more specific on the Compaq part number or provide a number like 5002US? A 900MHz Duron, but what about the motherboard bus speed? I saw a listing for the 5002US model with only a 200MHz bus speed... This could be your limiting factor in deciding what CPU would work for you
