Unless you modified your BIOS with a SPI flasher after disassembling your device, you know it's still running :-)
It would disappear from the PCI bus.
Your commands un-provision AMT (Active Management Technology), the ME feature that apparently has a security issue. Unless you've explicitly enabled AMT, it's not provisioned anyway so this doesn't do anything.
May be worth reading the coreboot wiki, I remember reading about the different subsystems of AMT, and it seems plausible that you can set it into a state where control functions are disabled. But my memories are very blurry.
Still coreboot guys are quite experts on the matter.
