I turned on one hidden feature in my old Dell laptop, and now I can see its BIOS from my desk
Worth it, asterisks and all.
A man found a hidden feature in his eight-year-old Dell laptop that allows him to access the BIOS remotely from his desk. This Dell Latitude 7480 laptop had Intel iTCO watchdog, which provided a watchdog capability but not a remote access feature. The man discovered Intel’s built-in remote management system, Intel Active Management Technology (AMT), while working on an ESP32 project.
AMT allowed him to reach the BIOS from his PC, eliminating the need to physically open the laptop. He enabled AMT and configured it through the MEBx menu, which exposed a web interface on port 16992 using HTTP digest-auth. This web interface provided various functions, including system status, hardware information, event logs, power controls, and management options.
The man used the web interface for a watchdog feature that could power-cycle the laptop remotely. However, it lacked a remote KVM interface, which he needed for a more advanced setup. He found MeshCommander, a client that supported AMT version 11.8.X.X, and enabled Redirection Port and KVM for remote control. MeshCommander gave him a live view of his Debian desktop, allowing him to access the BIOS and perform system-level settings.
Despite some vulnerabilities and maintenance concerns, the man believed AMT was a useful tool for remote firmware access in his existing hardware.
