System Configuration User Guide

If you set or change the BIOS User password, you cannot change any other BIOS option
using syscfg except the BIOS User and Administrator passwords.
Refer to the Product Guide for your Intel® Server Board for more information on BIOS
Setup options.
Examples:
syscfg /bup "" kwm93a3
syscfg /bup kwm93a9 lqts284
syscfg /bup lqts284 ""
syscfg /bap "" lqts284 /bup "" kwm93a3
Note: The /bup option can only be used if system has a valid Administrator password set.
Clearing the Administrator password will also clear the User password.
