AAEON UP4000 BIOS – How to require password only for BIOS setup, not at boot?

John02

Hello,

I am using an AAEON UP4000 board with the default AMI UEFI BIOS.

Currently I configured both passwords:

    Supervisor / Administrator password

    User password

The problem is that when the system boots it asks for the User password before booting the OS.

What I would like instead is this behavior:

          The system should boot automatically without asking for a password

          The password should be required only when entering the BIOS setup

Basically I want the BIOS to behave like this:

           OS boot → no password

           Enter BIOS setup → password required

I tried setting only the Supervisor password, but then the normal user can still modify many BIOS settings.

So my questions are:

Is there a BIOS setting like "Password Check = Setup" or "Security Option = Setup" on the UP4000?

          Is there any hidden BIOS menu where this option exists?

Is there a way to limit the capabilities of the User account in BIOS without requiring a password at boot?

Any advice from people using the UP4000 or AMI BIOS on embedded boards would be very helpful.

Thank you!
