Limitations

The following WMI limitations exist for BIOS setup:
• BIOS settings cannot be changed at the same boot as power-on passwords (POP) and hard disk
passwords (HDP). If you want to change BIOS settings and POP or HDP, you must reboot the system
after changing one of them.
• A password cannot be set using this method when one does not already exist. Passwords can only
be updated or cleared.
