BIOS backup is corrupt/bad read, try reading it again, are you using a clip/pogo pin adapter?
If yes, set a lower SPI clock speed on your programmer, try with 8 MHz and read the BIOS chip again
EDIT: This doesn't look like a PC BIOS at all, maybe there's another SPI flash chip on the boardComment

It's possible that one of the two flash chips is the BMC. I desoldered the second flash and attached it here. In a hex editor, it looks more like a BIOS.Comment

Hey guys,
have a laptop here that has a supervisor Password (dump in Attachements).
Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site

Anyway i wanted to ask what of the two chips is the ec bios because on the left... -
I have a Lenovo Thinkpad T14s Gen2 AMD (20xk-0053au type number) that I bought off ebay.
Naturally, the seller forgot to remove the supervisor password, and now is not replying. Due to shipping costs, it isn't really feasible to do a full return.
From what I can tell, to bypass the supervisor password I'd need to do an EC flash.
However, I still have 1 attempt on the password before it locks me out.
Thus, my questions are:
- If I get to a "SYSTEM DISABLE" state, will I still be able to boot the operating system etc?
- Does getting a "SYSTEM... -
I bought this laptop on vacation because the seller gave it to me for about 30 bucks converted USD. It's managed by some disbanded company but it worked fine. I was tinkering with it and secure wiped it because I wanted to reinstall windows 11 but the supervisor password locks everything and does not allow me to change anything in the bios menu/setup/etc. To get inside all I have to do is press enter when asked for the password, but other than that: can't change much. It sees me windows iso flash drive but won't allow me to change Secure Boot to let it boot.
Is a supervisor password... -
