[Problem] Boot Order Settings of Lenovo m710s

BIOS/UEFI Modding BIOS Modding Guides and Problems
1

Hi everyone,
I want to install Linux on my Lenovo M710s, but I can’t change the boot order, not even with F12. It also asks for a supervisor password; I bought the PC used. The seller doesn’t know anything either. I created a dump file using the CH341 programmer. Since I’m not a programmer, I have no idea how to proceed.

Thanks in advance,
crizz

Erasing lost or forgotten passwords (clearing CMOS)

To power ON when jumper shorted, several beeps after press/hold PSW button, restore jumper position.
Not just switching jumper and wait a few seconds.

EDIT:
With ME_DIS on or off? Try it.

I did this, but it doesn’t work. there were two beeps every 2-3 seconds. I also removed the battery, but that didn’t help. it cleared the time in BIOS, but not the pw. So I decided to READ the W25Q64JVSIQ chip. I made three copies. That’s interesting, but I have no idea where to start looking.
