The bios versions differ as do the manufacturers.
Also, each bios when sold to a mainboard manufacturer can have a customized setup program and so, the answer to your question is that it all depends what bios on what board.
This is a quote from your motherboard manual....from Gigabyte Technology website support area:
"The BIOS setup program allows you to specify two separate passwords:a SUPERVISOR password and a USER password" etc
"If you select "System" at "Security option" in Advance BIOS features menu you will be prompted every time the system is rebooted or any time you try to enter setup menu" etc etc
The short version....go to BIOS setup.....SYSTEM at SECURITY option should be set.
If it is set to SETUP and not SECURITY then you only get the password when you try to enter setup.
You have two setup password settings, one for supervisor which gives access to ALL the features of the bios, and one for USER which allows access to only basic BIOS features with a separate password.
Basically in answer to your question: YES...it has more features and therefore you need to know your bios.
If you need help downloading the PDF file for your mainboard manual let me know....I will get it to you.
