How is this Intel ME CPU patch deployed and where does it actually go? Is there some tiny flash in the CPU itself where the Intel ME code resides? Or does the patch get deployed as part of a UEFI firmware update, but isn't actually part of UEFI firmware, and somehow the CPU can reach out and grab its own updates from UEFI?
- close04 8y agoUsually 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).
- Kliment 8y agoThe 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)
- close04 8y agoActually 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.
