Parameter
Description
/Get:"filename" --or-- /GetConfig:"filename"
/Set:"filename" --or-- /SetConfig:"filename"
Gets the configuration data. NOTE: If "filename" is empty, BCU writes configuration data to the output console.

/cspwdfile:"filename" --or-- /CurSetupPasswordFile:"filename" --or-- /cpwdfile:"filename"
/nspwdfile:"filename" --or-- /NewSetupPasswordFile:"filename" --or-- /npwdfile:"filename"
/? --or-- /Help
Specifies the current BIOS Setup Password by providing an encrypted password file. Current password should be provided when changing BIOS settings or password. Can specify only one current password file. Use HPQPswd.exe to generate password file. See Password management on page 6 for additional details on this utility.
NOTE: Requires BCU version 3.0.1.1 or later.
If using a BCU version earlier than 4.0.1.1, use /cspwdfile:"filename".
Specifies the new BIOS Setup Password by providing an encrypted password file. To remove the password, use /npwdfile:"". Use HPQPswd.exe to generate the password file. See Password management on page 6 for additional details on this utility.

If using a BCU version earlier than 4.0.1.1, use /nspwdfile:"filename".
Displays a help message.
/SetDefaults

NOTE: /SetDefaults does not change every possible value; also, it does not change settings on an individual basis.
/verbose /WarningAsErr
When used with /Set, displays details about each setting, such as success, the reason for failure (warning), or failure code (error).
When used with /Set, displays details about each setting. Unlike /verbose,
2
any settings not applied due to warnings cause BCU to return program error code 13 instead of success.
Chapter 2 Command-line parameters
Parameter /Unicode /log /getvalue /setvalue /ot:value
/ar:value
/uid:value
Description
NOTE: Requires BCU 3.0.11.1 or later. When both /verbose and / WarningAsErr are used, /WarningAsErr will take precedence.
Checks platform support for Unicode passwords only. If not supported, returns error code 32. Use only in batch files; this command is not compatible with other commands. NOTE: Requires BCU version 4.0.1.1 or later.
Generates the log folder and log file default to the executable folder. NOTE: Requires BCU version 4.0.1.1 or later.
Gets the value of a given setting without using the config file.
Example: BIOSConfigUtility.exe /getvalue:"Asset Tracking Number"
NOTE: Requires BCU version 4.0.1.1 or later.
Sets the value of a given setting without using the config file.
Example: BIOSConfigUtility.exe /setvalue:"Asset Tracking Number","12345678"
NOTE: Requires BCU version 4.0.1.1 or later.
When this value is set to 0, a setting will be rejected if the anti-replay value specified is less than what is stored by the firmware. When this value is set to 1 a setting will be rejected if the anti-reply value specified is less than or equal to what is stored by the firmware. Since BCU uses the same anti-replay value for all the settings made within a file, when it is used with a settings file containing multiple changes, this value must be set to 0 or only 1 setting will get applied.
Provides AntiReplay value. The firmware compares the anti-replay value used for each setting with an internal value (initially 0). If the value provided with the setting is less than (or equal based on the /ot setting) to what is stored then the setting is rejected. If the setting is accepted. the firmware updates its internal value with the value used by the setting. This logic is used to prevent older settings from being reused for security reasons. A common method of simplifying the management of this value is to use the epoch / unix time in UTC as the value. The current values stored by the BIOS are available in the BIOS settings:
Provides the MachineID Universally Unique Identifier (UUID) this is available in the BIOS setting "Universally Unique Identifier (UUID)" and can be used to target the setting to a single platform. Using a value of FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF allows the settings to be applied on any machine. The default value is FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF.
3
/pkey:"*.pfx" /pkeypwd:value /addauthstr
Specifies the path /filename to the PFX file that contains the private key to use when signing the settings.
Optional. If the specified PFX file is password protected, this specifies the password to the PFX file
Generates BCU-AuthString.txt. NOTE: Includes the unique signature strings required to change BIOS settings on a system with HP Sure Admin enabled.
