HC08 monitor mode question

This is probably a dumb question, but I have not found a definitive answer to it:


As I understand things, a bootloader, which must be programmed onto the chip beforehand is required to program the HC08 series while in user monitor mode, which is the monitor mode that does not require an external clock and the high voltage Vtst.


It is also my understanding that if you do have the external clock and Vtst, you can program the chips without a bootloader (ie if you had a completely blank chip)


is this correct?  


Also, does the QY series come with this bootloader programmed in from the factory?
