Wow, I thought I recognised your name and I was right.
This thread comes from the person who wanted to flash an Asus mainboard from a P4P800 BIOS to a P4C800 despite them having different chipsets (so why would you want to)?
Also the person who dropped his hard disk and was surprised it won't work.
And the person who is adamant you can unlock the multipliers on a non-ES Intel chip despite the whole enthusiast community knowing Intel cuts the chips internally so you can't do this.
Now we have someone who wants to flash a 9200 to a 9500. As already said, these chips share NOTHING in common, they use different cores, have different pipeline configurations. Hypothetically, even if you could get it to flash right, why the hell would you want to? It won't do anything for it.
I'm sorry to have to say this but you really shouldn't be playing with computer equipment because you actually do have no idea what you are talking about and hence keep asking these questions...
