1 Introduction
The system BIOS in all HP ProLiant DL580 Gen8 servers includes an embedded UEFI Shell in the
ROM. Based on the UEFI Shell Specification the shell environment provides an API, command line
interfaces (CLI) that allows scripting, file manipulation, obtaining system information, and runs
other UEFI applications. These features enhance the capabilities of the UEFI System Utilities. Access
to the UEFI Shell is enabled by default.
