This command is used to configure UEFI settings.

Advanced Settings Utility commands (ASU) are used to configure UEFI settings. The host system must be rebooted for any UEFI setting changes to take effect.

Syntax:

asu [subset_command]

Table 1. asu subset commands
Command	Description	Value
help	Use this command to display help information for one or more settings.	setting_name
set	Use this command to change the value of a setting. Set the UEFI setting to the input value. Note Set one or more setting/value pairs. The setting can contain wildcards if it expands to a single setting. The value must be enclosed in quotes if it contains spaces. Ordered list values are separated by the equal symbol (=). For example, set B*.Bootorder "CD/DVD Rom=Hard Disk 0=PXE Network."	setting_name=value
show	Use this command to display the current value of one or more settings.	setting_name
showvalues	Use this command to display all possible values for one or more settings. Note This command will display information about the allowable values for the setting. The minimum and maximum number of instances allowed for the setting is displayed. The default value will be displayed if available. The default value is enclosed with opening and closing angle brackets (< and >). Text values show the minimum and maximum length and regular expression.	setting_name
showgroups	Use this command to display the available setting groups. This command displays the names of known groups. Group names may vary depending on the installed devices.
Note In the command syntax, setting_name is the name of a setting that you want to view or change, and value is the value that you are placing on the setting. setting_name can be more than one name, except when using the set command. setting_name can contain wildcards, for example an asterisk () or a question mark (?). setting_name* can be a group, a setting name, or all.
