No the platform is the hardware required to make a functional system..... You need a HTT controller to make the CPU work... It is a platform device. You need a SATA controller to make the harddrive work.... It is platform device....
Your definition of a platform is a completely built system, OS, and support, and marketing, and all.... Which is nonsense.. Maybe you should look up what an agency is...
No, my definition of a hardware platform is the hardware necessary to run software. I don't know how this is unclear. The definition you gave is from Intel's own definition of a complete system platform. If you don't like it, take it up with them, I'm sure they'd like a good laugh of a single person like you claiming you know more than the entirety of Intel. I wish you would, it would be funny.
And you need a CPU to make any of those controllers work. What's your point? I feel like I'm going in circles. Would you at least acknowledge that every definition found thus far by any reputable source online disagrees with your definition of platform?
How is a CPU not required for a functional system? I don't suppose you've ever tried to boot without a CPU.
