A USB recovery key can be created during password creation that can be used to recover system if password is lost or forgotten.ĪMI will begin offering this method of storing BIOS passwords immediately with the introduction of a new BIOS eModule called TpmPassword. Continuous read of TPM NVRAM with the wrong password will trigger a dictionary attack defense mechanism that will intentionally and steadily slow down an attack.Īs an added benefit of storing BIOS passwords in the TPM NVRAM, BIOS passwords are preserved even after a BIOS firmware flash and hardware reset. Malicious user cannot search NVRAM for the BIOS password hash. The TPM has inherent characteristic that counter attempts to gain access to its NVRAM. AMI has invested two years developing and testing, storing the BIOS password in the NVRAM of the TPM. However, anyone can read system NVRAM and an attacker can easily employ a Dictionary Attack, which is simply attempting to guess the password until a match is found.ĪMI raises the barrier higher with a drastically different approach not traditionally seen when it comes to BIOS password integrity. This method is easy for system manufacturers to implement and offers a good level of security because passwords are not saved in the clear. They are hashed and stored in system NVRAM. BIOS passwords are not stored in plain text. If the BIOS password is disabled by default, then the system can be infiltrated.Īdditionally, as more individuals begin to experiment with defeating BIOS passwords, the traditional method of storing the BIOS password weakens. However, it does not stop them from physically opening the system and resetting the BIOS to its default settings. Having a BIOS password along with a proper Boot Order setting, offers superior protection as it can raise the barrier against a malicious user from booting the system from external storage devices. Absent a Prema BIOS mod, this is really the only thing I need this for.BIOS passwords offer a stronger layer of system protection. I can boot internally on either UEFI or legacy modes, it's just that both aren't visible at once. Anything internal is an either/or scenario. The exception is external booting media, like USB flash drives. As it is now, I can only see UEFI *OR* legacy boot options at any given time, but not both at once. My main interest is in being able to see and interact with both legacy and UEFI boot options at the same time. But I do know that many BIOSes have hidden options that aren't normally visible. I don't really need anything modded, per se, like advanced overclocking options, etc. Sager doesn't make my BIOS available for download, nor have they issued any updates for it.
I plan on submitting a BIOS mod request at the forum, in exchange for a donation. But I need an exact byte-for-byte copy, and I need it to be complete. Perhaps my BIOS is just too new? In this program I can also select custom sizes, the largest of which is 16384K. I have already tried backing up the BIOS with Universal BIOS Backup Toolkit, but it errors out with "Cannot identify the BIOS". I assume that AM is the BIOS, and Aptio is just the name of the setup utility. In my BIOS it says "American Megatrends" and "Aptio Setup Utility". I have a Sager NP9876/Clevo P870KM1-G gaming notebook.
