Lpc2000

Umm.....Some questions, don't mind:
- How do I know there is no Trojan Horse inside??
- How do I know your code does not over-cooked my flash??
  or make it raw/medium when I actually ordered well done??
- How do I know your code could handle Exception Interrupt 
  properly?? without crashing??
- How do I know your code does not have CSI bugs??
- How do I know if you could understand the watchdog hardware
  in detail and handle it properly upon a watchdog reset event??
- How do I know if I will not have CRP problem, after installing
  your that boot loader?? And What's that "CRP feature to extent
  supported by hardware"??
- How do I know if you are able to get Philips to ship with your
  bootloader?? Or I need to re-load everychip? Or you could 
  provide free bootloader upgrade every chip programming 
  services??
- How do I know if you are Philips Certified/Appointed consultant??
Thanks!!
