Re:Intel patches new ME vulnerabilities

Usually a separate patch, an ME firmware patch. The ME is physically located in the chipset but I'm not entirely sure where the FW resides, whether the chipset or a flash on the motherboard (sharing with the system UEFI/BIOS).

The ME firmware lives on an SPI FLASH chip, on the motherboard. It can either be the same chip where the BIOS is stored or a separate one (which is often the case because two smaller chips cost less than one big one)
Actually you're right. Since most of the analysis on the ME FW was done after dumping the flash from the physically removed clip on the motherboard. That might have been more difficult with a chipset embedded one.
