Desktop Management Interface

The system BIOS (UEFI BIOS) of your computer supports an interface called System Management BIOS
Reference Specification(SMBIOS) V2.6.1. SMBIOS provides information about the hardware components
of your system. It is the responsibility of the BIOS to supply this database with information about itself
and the devices on the system board. This specification documents the standards for getting access to
this BIOS information.
Preboot eXecution Environment
Preboot eXecution Environment (PXE) technology makes your computer more manageable (it is PXE
2.1-compliant) by enabling it to boot (load an operating system or another executable image) from a server.
Your computer supports the PC functions that PXE requires. For example, with the appropriate LAN card,
your computer can be booted from the PXE server.
Note: Remote Program Load (RPL)cannot be used with your computer.
Wake on LAN
A network administrator can use Wake on LAN to turn on a computer from a management console.
When Wake on LAN is used with network management software, many functions, such as data transfer,
software updates, and Flash updates of UEFI BIOS, can be performed remotely without remote attendance.
This updating can be done after normal working hours and on weekends, to save time and increase
productivity. Users are not interrupted during normal working hours, and LAN traffic is kept to a minimum.
If a computer is turned on by the Wake on LAN function, the Network boot sequence is used.
