STM32 boot program

Hi all,
We had procured some sample STM32F105VCT6 ICs and were able to program the device through the serial port (USART1). Later we procured some from a local vendor. These are not getting programmed. On searching the net for possible causes, I came across "internal code" or "blank". What is this internal code? Do all STM32F103/105s have boot loaders? or do we have to explicitly order parts having boot code? Thank you for your time.

Regards
Partha
