[Request] Zotac Magnus One AMI Bios unlock
#1
I have been trying to unlock the bios of the Zotac Magnus One mini PC.  It is running AMI BIOS and I have successfully dumped the firmware and can confirm it is not locked.  Using AMIBCP I was able to modify a few parameters and reflash back using AMI Flash tool (afuwin).  I cannot for the life of me figure out how to unlock the menus.  I am including the dump from my BIOS.  I would greatly appreciate someone who has more knowledge than I do on this to see if there is anything I may be missing or can do to unlock these menus.  I would love to be able to enable XMP and also undervolt the CPU.  Thanks so much in advance for any assistance with this.

1. I have questions ,you said you edit bios via ambcp then re-flash again ,after flash the modified bios , does it still boot up normally?

2. I don't think afuwin is a valid flash tool for bios modification ,sometime even if you seen it flashed complete ,but in fact nothing be wrote. First you could test this mod and check if there any changes under OC tab.

Hi yes, I was able to successfully modify parameters in the bios dump made with afuwin and then re-flash using the same tool again.  The system booted normally.  Also I then took another read of the bios image and could see the settings persisted.  I would just love to get some of the menus unlocked since this would be way more convenient.  I will try what you suggested and report back.  Thanks!

Wow this worked! Can I ask which parameter you modified to get this to show up? Under the features menu I now have another menu that has firmware Configuration and I can switch it from production, test, or ignore policy update. Under this I now have system agent configuration and pch-io configuration. I can see the memory timings and adjust them and the PCH thermal throttling control as well. I don't have access to the CPU overclock and voltage settings however just yet. Thanks again for your help with this!

1. No file can let you download ,because mod is only for individual machine. You should attach your bios dump to modify.

2. First make a bios dump with this tool then attach file (Run dump.bat as administrator.).

Hello @genius239

I'm a good friend of tima_ficus, I have another zotac magnus one (buy two of them on the same day Smile ), he recommended your's contact, he's delighted with what you did!
How i understand this mod is only for individual machine. I will be very grateful to you if you have time to make a dump mod

Thank you, best regards

I made a dump and attached it to the post.
