What Is BIOS Self-Heal And How Does It Work?
BIOS Self-Heal is a feature that allows the BIOS to recover from corruption or damage by automatically restoring a backup copy of the BIOS firmware. This feature is designed to prevent the system from becoming unbootable due to a corrupted BIOS. When the BIOS detects that it has become corrupted, it will automatically switch to the backup copy and restore the system to a functional state.
The BIOS Self-Heal process typically involves the following steps: the system detects a corrupted BIOS, the backup BIOS is activated, and the corrupted BIOS is replaced with the backup copy. This process is usually transparent to the user and does not require any manual intervention. The system will then reboot and continue to function normally, with the restored BIOS taking control of the system’s hardware.
What Are The Benefits Of Using BIOS Self-Heal?
The main benefit of using BIOS Self-Heal is that it provides a high level of protection against BIOS corruption, which can cause the system to become unbootable. By automatically restoring a backup copy of the BIOS, the system can quickly recover from corruption and continue to function normally. This feature is particularly useful in mission-critical systems where downtime can have serious consequences.
Another benefit of BIOS Self-Heal is that it eliminates the need for manual BIOS recovery, which can be a time-consuming and complex process. With BIOS Self-Heal, the system can recover from corruption quickly and easily, without requiring any technical expertise. This feature is also useful in situations where the system is located in a remote location, making it difficult to access and repair.
How Do I Enable BIOS Self-Heal On My System?
