1.1.4 BIOS Setup – Security Menu

Figure 6 displays the Security menu. This menu gives you access to virtualization-related features such as

Intel VT, Intel TXT and Intel VT-d. It also allows you to set passwords for platform- and hard drive-level

security and to control the Execute Disable Bit (XD) technology and Chassis Intrusion features.

Figure 6. BIOS Setup - Security Menu

Note

: Intel VT must be enabled before Intel TXT. Once Intel TXT is enabled, the user cannot disable

Intel

VT unless Intel TXT is disabled first.

Note

: Setting the Master Key Hard Disk Drive Password will not enable Hard Disk Drive password security.

Only by setting the Hard Disk Drive Password will the system pause during boot to ask for a password. At

that time either the Hard Disk Drive Password or the Master Key Password (if set) will allow the system

to proceed.

Note

: The Supervisor Password controls access to the BIOS Setup menus. The User Password controls

booting the platform and is separate from the Hard Disk Drive Password. The User Password is stored in

the Intel Desktop Board DQ57TM non-volatile RAM and stays with the platform, whereas the Hard Disk

Drive Password is stored directly on the HDD and is portable with it.
