ThinkPad T14 Supervisor password

[BMCappelletti]

Password in SIO. you need vertyanov successor or Svod 4 programmer.

Someone wrote here that patching was not doable on 32MB BIOS chip.
I have a T14 gen 1, but it has a 16MB BIOS. Any chance?
I see some people that after trying the patch only got black screen. I don't want to risk, as the machine is usable. Although I could write the original file later if that happens.

Hi! I am excited to learn about these chips. Can someone tell me if one of these chips is the embedded controller with the supervisor password stored on it?

This is on a NM-C801 motherboard from a T14 Gen 1 w/AMD Ryzen 7.
ITE IT8300FN
or
ITE IT5261VG-256

Thank you!

Re: ThinkPad T14 Supervisor password

Has anyone read the EC IT8300 chip, from thinkpad T14 AMD, using RT809? Mine is giving an error and even with everything right, would there be any other modification on the board that I do to make the reading? I don't have vertyanov and I don't have svod.

Has anyone managed reading EC IT8300 on thinkpad T14 AMD, using RT809??
