Introduction
Asus 12th and 13th generation NUCs with vPro and AMT (Active Management Technology) have been reported to have issues with OS boot. This article will provide a detailed explanation of the problem, its causes, and possible solutions.
Understanding vPro and AMT
vPro and AMT are technologies developed by Intel for remote management of computers. vPro is a platform that includes several features, such as hardware-based security, while AMT is a feature of vPro that allows for remote out-of-band management of the computer. This means that even if the operating system is not running, AMT can still be used to manage the computer.
Issue with OS Boot
The issue with the Asus 12th and 13th generation NUCs with vPro and AMT is that the OS boot process is inaccessible. This means that users are unable to access the OS boot menu, which can prevent them from booting into a different operating system or performing a system recovery.
Causes of the Issue
The issue is caused by a combination of factors, including the NUC's UEFI (Unified Extensible Firmware Interface) settings and the vPro/AMT configuration. Specifically, the issue is related to the "POST" (Power-On Self-Test) process, which is a series of tests that the computer runs when it is turned on to ensure that all of its hardware is working properly.
POST Process
The POST process is controlled by the computer's BIOS (Basic Input/Output System), which is a type of firmware that is stored on a chip on the motherboard. The BIOS is responsible for initializing the computer's hardware and loading the operating system. In the case of the Asus 12th and 13th generation NUCs with vPro and AMT, the issue is that the BIOS is not properly handling the POST process when vPro/AMT is enabled.
vPro/AMT Configuration
The vPro/AMT configuration can also contribute to the issue. Specifically, if the vPro/AMT settings are not properly configured, it can prevent the OS boot menu from being displayed. This is because vPro/AMT takes control of the computer's hardware during the POST process, and if it is not configured correctly, it can interfere with the OS boot process.
Possible Solutions
There are several possible solutions to the issue, including resetting the UEFI settings, disabling vPro/AMT, and updating the BIOS. It is also recommended to check the Asus website for any firmware updates that may address the issue.
Resetting UEFI Settings
Resetting the UEFI settings can often resolve the issue. This can be done by restarting the computer and pressing the appropriate key (usually F2 or DEL) to enter the UEFI setup. From there, the user can reset the UEFI settings to their default values.
Disabling vPro/AMT
Disabling vPro/AMT can also resolve the issue. This can be done by entering the UEFI setup and disabling the vPro/AMT feature. However, this will also disable the remote management capabilities of the computer.
Updating BIOS
Updating the BIOS can also resolve the issue. This can be done by downloading the latest BIOS version from the Asus website and installing it using the Asus update tool. However, it is important to note that updating the BIOS can be a complex process, and it is recommended to follow the instructions provided by Asus carefully.
The issue with the Asus 12th and 13th generation NUCs with vPro and AMT and inaccessible OS boot is caused by a combination of factors, including the UEFI settings and the vPro/AMT configuration. However, there are several possible solutions, including resetting the UEFI settings, disabling vPro/AMT, and updating the BIOS. It is also recommended to check the Asus website for any firmware updates that may address the issue.
