Hello-- I am running F9 on an older box that has a Pentium 4 non-hyperthreaded processor--it works great. I want to plop in a hyperthreaded processor--let's assume here that the processor and mainboard are compatible and working fine together. When I fire this system back up, how will the kernel react? I have read that SMP is built into the kernel already, so will it simply pick up on the "extra" processor and begin working in hyperthreaded/dual processor mode or will this be an OS rebuild event (or something in between)?
