Once such an update is carried out the firmware updater asks for your system to restart. The ME firmware updates are sent using the Intel firmware update utility (which also runs within Windows in a command prompt window) to the physical Intel ME firmware of your system. The MEI driver is the most critical part of the ME software to keep updated.Īll of the Intel ME software only runs in Windows. The ME software also generally includes the MEI (Management Engine Interface) driver for Windows. The Intel ME software consists of components such as management software for the TPM and an Intel Licensing service (I’m not sure what that is used for) and some other utilities. I say routine here since this would be a later time after first setting up your system. Intel ME software updates may or may not be updated at the same time as the Intel ME firmware, in such cases just use the most recent software available at the time. I don’t recall where I read this (I believe it was from Intel’s ME firmware release notes) but when you are routinely updating the Intel ME firmware you should first update the Intel ME software (if such an update is available). Yes, I would agree with that order of installation you listed. In general, you download and install the updates separate to one another.Ģ. However, most of the time, Intel ME firmware updates and BIOS updates are carried out separately. When control is returned to you, you’ll see both the BIOS and Intel ME have been updated (both version numbers are higher). While you have only initiated the installation of the BIOS update, the check on the Intel ME firmware is performed in the background.įrom having installed such bundled updates myself, you usually aren’t aware multiple stages of updates are taking place but I have noticed that such updates cause the system to reboot twice automatically. If the currently installed ME is the same version or newer, only the BIOS update is installed. When running such a bundled BIOS update, it checks if the current in-use ME firmware is older than the version bundled with the BIOS update, if it is the ME firmware is also updated. However, to add to the confusion some manufacturers e.g., Dell and Asus sometimes include Intel ME firmware updates within some of their BIOS updates for their systems. No, a BIOS update is separate to an Intel ME firmware update. I hope these explanations are useful, despite their length. Just to add to the confusion, the Intel ME software and Intel ME firmware use different version number schemes e.g.
I will describe the answers to your questions in more detail below. Both are stored within chips on your motherboard but are physically separate. Alex5723 is correct, the BIOS and Intel ME firmware are two different things.
