Appendix D: EFI Shell Commands
The embedded EFI Shell must be accessed when running any of the system update utilities or
Platform Confidence Test (PCT). The embedded EFI Shell can be accessed by booting the
system and entering the BIOS Setup utility (F2) during POST. From the BIOS Setup utility Main
menu, tab over to the Boot Manager menu and select EFI Shell.
The following is a list of supported EFI Shell commands. Most shell commands can be invoked
from the EFI shell prompt. However there are several commands that are only available for use
from within batch script files. The following table lists all the commands and provides more
details on each command. The “Batch-only” column indicates if the command is only available
from within script files.
