What happens if i.e, in the IDT entry 0, I set the P (Present) bit to zero?
That translate to not handling a possible zero division.
Suppose the CPU does a zero division… what happens in this case?

In this case you should get a #GP. If the #GP handler is not present, you’ll probably end up in Triple-Fault Shutdown.
