From what I've read, the Celeron 1.7 cpu is a bit of a dog, so I'm thinking of replacing it w/ a P4 either 2.2, 2.4, 2.6 as long as it has a 400 FSB, it should be ok, right?
My question is this: do I need to update the BIOS? It presently is version A00, and I see on Dell's support site there are flash updates for A00, A01, and A02. Do I need to flash the BIOS before installing the P4? If I don't, will the machine explode?
