I have an Esprimo Desktop, model P5731. A few months ago I set a supervisor password to protect only the setup program. The operating system I can run but I can't enter the BIOS settings.
BIOS Version: Phoenix 6.00 R1.05.3011.A1.
Removing the battery does not reset the password, but only reset the BIOS settings.
How to reset or recover the BIOS master password?
Many thanks in advance to anyone who can help.
