Ok.  The starter kit isn't realy a put together kit, its a take it out of
box kit.

I don't know.  It just depends on the motherboard.

I'd get the starter kit though, its supposed to come with 2 parts anyway...

It takes an expensive programmer to enable the bit, but you can buy the
chip with the bit pre-set.  Look for 'A' in the part number.
