+To help you identify what is a string that you want and what is not, consider the following: <br>
 • ALL of the item strings in the TEMPLAT module will follow the format described above, no what their length happens to be. The string will always start with the 1st byte telling you the type of string and the second byte telling you the length of the string (in hex) and so on.

+To help you to better identify registers in differently sized strings as well as this one: <br>
 • The options of the BIOS setting will ALWAYS come after the register. Likewise, the register will ALWAYS be the word (2 bytes) that comes before the options of the BIOS setting. For the VT-x setting, we know that there are only 2 options; "enabled" and disabled". Each option will take up 1 word (2 bytes). Skip a total of 4 bytes from the end of the VT-x string. The 2 bytes before these 4 end bytes will be the bytes that constitute the register. NOTE: I will be posting another mini-tutorial within this tutorial describing how to trace what you suspect is a setting-name (enabled, auto, etc.) to STRINGS0.ROM to determine where the settings begin/end so that you can easily find the register (It is actually the same process used to trace the register and the item string call).
