An aide memoire for me.
Removing the unknown supervisor or user BIOS password
Open the machine up, and remove the yellow jumper.
Boot the machine, and it should boot into the BIOS.
Press “2” to wipe the passwords.
Reboot the machine.
0x1a security violation
If you get a message showing error code
0x1a security violation, it is likely that the machine is enforcing Secure Boot.
If you are using
Ventoy, try this from the Ventoy manual:
- Press “Ok”
- Press any key to perform MOK management
- Enroll key from disk
and you should see Ventoy appear.
