Today's update reset the bios password

Recommended Posts

It also reset my overclock settings (VRAM, MHz, etc). I'm unable to restore my custom settings due to not having the bios password anymore (Piano18482 is no longer the valid password). Also made me reset my Windows 10 password.

That's frustrating... I literally just bought RAM and was planning on updating the BIOS.

 

I know in the past there's a few things you can do... usually the CMOS/UEFI has a default password by the manufacturer. If anyone knows who the manufacturer is, you can use Google search/hack codes to pull it out of text files on file shares. There's also several other applications you can download which will pull the information from the address location on the CMOS where the password is stored ... that said, I don't know how that affects the new secure boot feature. Does the Atari VCS have a TPM module and all that crap?

We all feared this before... ☹️

I haven’t run the update, what happens if you disabled the supervisor password?

Are you referring to the bios password? If so, you can’t remove it until you log in with the correct password which is unknown at this point.

Look in the garbage file.

Anyone having issues with the update installing?  I keep getting message saying update is downloading in the background but never actually installs.  If I try to update manually I keep getting update failed error.

Do you mean you tried to do system update from the System menu? I never tried that.

The system update ran automatically at startup and completed no problem, first time.

However, because I had changed the BIOS setting relating to secure boot only, I got into a boot loop for the BIOS update.
That is, it tried to do it, but could not, and rebooted, and then tried again. (I could have bypassed it but wanted the improvements.) 
I reverted that change and then it completed OK. Anybody changing the BIOS settings of course needs to know how to revert back.

Maybe you have something like that with the BIOS? It's not clear to me where and how it does not work from what you wrote. Sorry.

It’s the system update that fails. Secure boot is enabled. Fails on step 2 of 3.

Definitely create a ticket with support.  Include this pic.  They should be able to walk you through it and get it accomplished.

The BIOS update doesn't help against the paper-clip method. It seems they implemented some extra BIOS checking during boot of the AtariOS. Yet, I dont care...I dont use it anymore...

I received a reply from Atari support apparently this is a known issue.  In case anyone else needs them these  are the steps they suggested I take.  I haven’t tried them myself yet.

I have been working on this problem for the past few days trying to find a solution.  The previous method of exposing the BIOS password was removed in the BIOS itself. The new .20 update actually removed the EFI Variable

SystemSupervisorPW

which was storing the password in cleartext.  While a new variable showed up called

AdminPassword

it does not have readable data, despite trying several attack vectors to retrieve something from it.

 

My next attempt to unlock the system was to try and unlock the BIOS itself. Atari has locked it down at the BIOS level using an EFI feature called SMM (I think?). I have experimented with trying to disable SecureBoot and other settings from UEFI Shell, with no success. Each attempt to write to a variable results in a fail, which means the variables are all Read Only or being blocked by the BIOS itself. 

 

SO without the password, I don't think there is anything more we can do. I for one find this to be complete B.S. as the whole point of "PC MODE" is to install an alternative OS.  But now, it is ONLY an OS that has SecureBoot capability. This eliminates systems like Lakka or Batocera and others that have not signed or shimed their kernels and bootloaders. 

 

Anyone else tried anything with different results?

These are clearly the hallmarks of quality.  It's just that it's spelled 'kwality' in this instance.

Is there an easy way to block this update?  I am afraid to turn on my VCS now given it could update it self and if I wanted to get into my Bios I won’t be able to.  Preferably a method without blocking out Atari Store or anything else like that out.

My rEFInd bootloader stopped working. Also lost my memory overclock and addition video memory. I may try the paper clip trick soon if another solution isn't found.

Update: Welp, I got impatient and did the paper clip thing. Worked! Back to where I was before the update. Prefer a password, but this works. Thanks @Charles Darwin!

I feel sure that we'll have a positive resolution for the long-term, in the not-too-distant future.
Call me an optimist, yeah, but it's not without reason. :-) I've no inside-information. It's a guess!
As a result, I'll be patient again.

So don't update my Atari OS till a solution is found? Got it. I guess in this case I'm lucky to have to use my phone as a hotspot to get online. Hopefully this can be solved soon so that those of you that updated can get back into the bios.
