Question Need some advice on some server equipment I bought on ebay. Lenovo X3550 M5. Locked out of the BIOS.

Now my curiosity is going to get the better of me. One thing I noticed earlier was that there are two jumpers—one for the CMOS, one for the UEFI. I can run the system without the jumper in place on the UEFI, but still have to supply the unknown password. I wonder if there is something wrong with the board.

Did you check the HMM for what the jumper does?

Yea, and then they use the password to access it. So I’m curious if it’s possible. This would be quite a change if it’s possible.

There’s not much else to the article

Maybe this method if OneCLI doesn’t work:

You’ll need a flash drive, 32GB should work

OK, I tried this and it didn't work. So I decided to take the CPUs, RAM, and possibly heatsinks and build a new system. Hopefully this works out.

Yeah, it says right on the board lol. A lot of the stuff is documented really well. I wish they all were that way.
