Questions and answers

1. How can the BIOS settings be restored (returned to factory settings)?

IMPORTANT: Restore defaults does not securely erase any data on your hard drive. See question and

answer 6 for steps to securely erase data.

Restore defaults does not reset the Custom Secure Boot keys. See question and answer 7 for

information about resetting the keys.

a. Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”

message is displayed at the bottom of the screen.

b. Select Main, and then select Restore defaults.

c. Follow the on-screen instructions.

d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.

2. What is a UEFI BIOS, and how is it dierent from a legacy BIOS?

The Unied Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface

between the platform rmware and an operating system (OS). It is a replacement for 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

conguration settings and to change the conguration of your computer before an OS is loaded. BIOS

provides a secure run-time environment that supports a Graphic User Interface (GUI). In this

environment, you can use either a pointing device (Touchscreen, TouchPad, pointing stick, or USB

mouse) or the keyboard to navigate and make menu and conguration 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 run-time 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 rmware 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 does the UEFI BIOS reside?

The UEFI BIOS resides on a ash memory chip. A utility is required to write to the chip.

4. What kind of conguration data is stored on the DIMM Serial Presence Detect (SPD) memory

module? How would this data be written?

The DIMM SPD memory contains information about the memory module, such as size, serial number,

data width, speed/timing, voltage, and thermal information. This information is written by the module

manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is

installed in a PC. Third-party tools do exist that can write to the EEPROM when the memory module is

not installed in a PC. Various third-party tools are available to read SPD memory.

5. What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?

This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains PC conguration

data.

6. How can the BIOS security be reset to factory defaults and data erased?
