What is a UEFI BIOS, and how is it different from a legacy BIOS?
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface
between the platform firmware and an operating system (OS). It replaces the older BIOS
architecture but supports much of the legacy BIOS functionality.
Like the legacy BIOS, the UEFI BIOS provides an interface to display the system information and
configuration settings and to change the configuration of your computer before an OS is loaded.
BIOS provides a secure runtime environment that supports a Graphic User Interface (GUI). In this
environment, you can use either a pointing device (touch screen, touchpad, pointing stick, or USB
mouse) or the keyboard to navigate and make menu and configuration selections. The UEFI BIOS
also contains basic system diagnostics.
The UEFI BIOS provides functionality beyond that of the legacy BIOS. In addition, the UEFI BIOS
works to initialize the computer's hardware before loading and executing the OS; the runtime
environment allows the loading and execution of software programs from storage devices to
provide more functionality, such as advanced hardware diagnostics (with the ability to display more
detailed system information) and advanced firmware management and recovery software.
HP has provided options in Computer Setup (BIOS) to allow you to run in legacy BIOS, if required by
the operating system. Examples of this requirement would be if you upgrade or downgrade the OS.
3.
Where is the UEFI BIOS located?
The UEFI BIOS is located on a flash memory chip. You must use a utility to write to the chip.

What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory
module? How would this data be written?
