Safety is a critical consideration when using a tool of this nature. Modifying firmware is inherently risky; a single error in the insertion process or a checksum mismatch can lead to a "brick," rendering the motherboard unable to post. Experienced modders always recommend having a hardware programmer, such as a CH341A, on hand before flashing a modified BIOS created with MMTool.

Save the modified file and prepare for the (often risky) flashing process. A Word of Caution --- Mmtool Aptio 4.50.0023
