7 Configuring server boot options on 14th generation Dell EMC PowerEdge servers
2.2 Boot mode BIOS settings
The BIOS Boot Mode can be set by using a number of interfaces: BIOS User Interface, RACADM command
line interface (CLI), iDRAC WS-Man, iDRAC RESTful application programming interfaces, and also an iDRAC
Server Configuration Profile (SCP) file. Throughout this technical white paper, examples are provided by
using the BIOS user interface and RACADM CLI. For more information about using WS-Man, iDRAC RESTful
API, or an SCP file to configure PowerEdge BIOS settings, visit the iDRAC home page
delltechcenter.com/idrac to access the product documentation, white papers, and other resources.
When using the BIOS user interface or RACADM, use these attributes to set the BIOS boot mode:

Note: BIOS attribute changes require a server reboot to make the changes effective. Changes to BIOS
attributes such as those shown in the following examples mark the attributes with pending changes; those
changes are applied when the server is rebooted.
