Lists all installed BIOS-controlled storage devices.

When a device is selected, detailed information and options are displayed. The following optionsmay be presented:

  • Hard Disk: Size, model, firmware version, serial number, connector color.

    Translation mode (ATA disks only)Lets the end-users to select the translation mode to be used for the device. This enables the BIOS to accessdisks partitioned and formatted on other systems and may be necessary for users of olderversions of UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift, LBA Assisted,User, and Off.

    Available only when the drive translation mode is set to User, allows to specify theparameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate diskI/O requests (from the operating system or an application) into terms the hard drive canaccept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256.The number of sectors per track may not exceed 63.


    Ordinarily, the translation mode selected automatically by the BIOS should notbe changed. If the selected translation mode is not compatible with the translation mode thatwas active when the disk was partitioned and formatted, the data on the disk will beinaccessible.

  • CD-ROM: Model, firmware version, serial number, connector color (not included for USB CDROM).

  • SSD Life Used:


    Displays for solid-state drives.

  • SMART (ATA disks only)

  • Diskette: Model and firmware version.


    Displays for USB diskette drives.

  • Default Values (ATA disks only)

    See Translation mode above for details.

    SATA Defaults

Storage Options

SATA Emulation

Allows you to choose how the SATA controller and devices are accessed by the operating system.There are three supported options: IDE, RAID, and AHCI (default).


SATA emulation changes may prevent access to existing hard drive data anddegrade or corrupt established volumes.

  • IDE - This is the most backwards-compatible setting of the three options. Operating systems usuallydo not require additional driver support in IDE mode.

  • RAID - Allows DOS and boot access to RAID volumes. Use this mode with the RAID device driverloaded in the operating system to take advantage of RAID features.

  • AHCI (default option) - Allows operating systems with AHCI device drivers loaded to takeadvantage of more advanced features of the SATA controller.


The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driverinstalled, the system will crash (blue screen). RAID volumes may become corrupted if they arebooted to after disabling RAID.

Removable Media Boot:

Enables/disables ability to boot the system from removable media. Default is enabled.

DPS Self-Test

Allows to execute self-tests on ATA hard drives capable of performing the Drive ProtectionSystem (DPS) self-tests.


This selection will only appear when at least one drive capable of performing the DPS selftestsis attached to the system.

Boot Order

Allows to:

  • EFI Boot Sources: Specify the order in which EFI boot sources (such as a internal hard drive,USB hard drive, USB optical drive, or internal optical drive) are checked for a bootableoperating system image. Each device on the list may be individually excluded from or includedfor consideration as a bootable operating system source.EFI boot sources always have precedence over legacy boot sources.

  • Legacy Boot Sources: Specify the order in which legacy boot sources (such as a networkinterface card, internal hard drive, USB optical drive, or internal optical drive) are checked fora bootable operating system image. Each device on the list may be individually excluded fromor included for consideration as a bootable operating system source.

Specify the order of attached hard drives. The first hard drive in the order will have priority inthe boot sequence and will be recognized as drive C (if any devices are attached).


To drag a device to a preferred place, press Enter. To remove the device fromconsideration as a bootable device, press F5.

F5 can be used to disable individual boot items, as well as disable EFI boot and/or legacy boot.


MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating systemhas started.

Shortcut to temporarily override boot order:

To boot one time from a device other than the default device specified in Boot Order, restart thecomputer and press Esc (to access the boot menu) and then F9 (Boot Order), or only F9 (skippingthe boot menu) when the monitor light turns green. After POST is completed, a list of bootabledevices is displayed. Use the arrow keys to select the preferred bootable device and press Enter.The computer then boots from the selected non-default device for this one time.

Computer setup - Security


Support for specific Computer Setup options may vary depending on the hardwareconfiguration.



Setup Password

Allows to set and enable a setup (administrator) password.


If the setup password is set, it is required to change Computer Setup options, flash theROM, and make changes to certain plug and play settings under Windows


Allows to set and enable a power-on password. The power-on password prompt appears aftera power cycle or reboot. If the user does not enter the correct power-on password, the unit will notboot.

Password Options(This selection appearsonly if a power-onpassword or setuppassword is set.)

Allows to enable/disable:

  • Lock Legacy Resources (determines whether or not Windows Device Manager is allowed tochange resource settings for serial and parallel ports).

  • Stringent security (enabling the stringent password disables the ability to reset the password bymoving the jumper on the system board). Default is disabled.


    If you enable the stringent security feature and you forget the setup password orthe power-on password, the computer is inaccessible and can no longer be used.

    If you lose or forget the password, the system board must be replaced. This scenario is notcovered under warranty.To prevent the computer from becoming permanently unusable, record your configured setuppassword or power-on password in a safe place away from your computer. Without thesepasswords, the computer cannot be unlocked.

  • Setup Browse Mode (appears if a setup password is set) (allows viewing, but not changing,the F10 Setup Options without entering setup password). Default is enabled.

  • Password prompt on F9 & F12 (requires setup password to use these boot functions). Default isenabled.

  • Network Server Mode. Default is disabled.

Smart Cover

Allows to:

  • Lock/unlock the Cover Lock.

  • Set the Cover Removal Sensor to Disable/Notify User/Setup Password.


Notify User alerts the user that the sensor has detected that the cover has been removed.Setup Password requires that the setup password be entered to boot the computer if the sensordetects that the cover has been removed..

Device Security

Allows to set Device Available/Device Hidden (default is Device Available) for:

  • Embedded security device

  • System audio

  • USB controller (varies by model)

  • Network controller


    You must disable AMT before trying to hide the network controller.

  • Serial port

  • Parallel port

  • SATA ports (varies by model)

USB Security

Allows to set Enabled/Disabled (default is Enabled) for:

  • Front USB Ports

  • Rear USB Ports

  • Accessory USB Ports

Slot Security

Allows to disable any PCI or PCI Express slot. Default is enabled.

Network Boot

Enables/disables the computer’s ability to boot from an operating system installed on a networkserver. (Feature available on NIC models only; the network controller must be either a PCIexpansion card or embedded on the system board.) Default is enabled.

System IDs

Allows to set:

  • Asset tag (18-byte identifier), a property identification number assigned by the company to thecomputer.

  • Ownership tag (80-byte identifier) displayed during POST.

  • Universal Unique Identifier (UUID) number. The UUID can only be updated if the currentchassis serial number is invalid. (These ID numbers are normally set in the factory and are usedto uniquely identify the system.)

  • Keyboard locale setting for System ID entry.

Master Boot RecordSecurity

Enables/disables Master Boot Record (MBR) security.

The MBR contains information needed to successfully boot from a disk and to access the data storedon the disk. Master Boot Record Security may prevent unintentional or malicious changes to theMBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It alsoallows you to recover the "last known good" MBR, should changes to the MBR be detected whenthe system is restarted.

When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of thecurrent bootable disk while in MS-DOS or Windows Safe Mode.


Most operating systems control access to the MBR of the current bootable disk; the BIOScannot prevent changes that may occur while the operating system is running.

Restores the backup Master Boot Record to the current bootable disk. Default is disabled.

Only appears if all of the following conditions are true:

  • MBR security is enabled

  • A backup copy of the MBR has been previously saved

  • The current bootable disk is the same disk from which the backup copy was saved


Restoring a previously saved MBR after a disk utility or operating system has modifiedthe MBR, may cause the data on the disk to become inaccessible. Only restore a previously savedMBR if you are confident that the current bootable disk's MBR has been corrupted or infected with avirus.

System Security(these options arehardware dependent)

Data Execution Prevention (enable/disable) - Helps prevent operating system security breaches.Default is enabled.

SVM CPU Virtualization (enable/disable). Controls the virtualization features of the processor.Changing this setting requires turning the computer off and then back on. Default is disabled.

Virtualization Technology (VTx) (enable/disable) - Controls the virtualization features of theprocessor. Changing this setting requires turning the computer off and then back on. Default isdisabled.

Virtualization Technology Directed I/O (VTd) (enable/disable) - Controls virtualization DMAremapping features of the chipset. Changing this setting requires turning the computer off and thenback on. Default is disabled.

  • Virtualization Technology Directed I/O

Embedded Security Device (enable/disable) - Permits activation and deactivation of the EmbeddedSecurity Device.


To configure the Embedded Security Device, a Setup password must be set.

  • Reset to Factory Settings (Do not reset/Reset) - Resetting to factory defaults will erase allsecurity keys and leave the device in a disabled state. Changing this setting requires that yourestart the computer. Default is Do not reset.CAUTION: The embedded security device is a critical component of many security schemes.Erasing the security keys will prevent access to data protected by the Embedded SecurityDevice. Choosing Reset to Factory Settings may result in significant data loss.
  • Measure boot variables/devices to PCR1 - Typically, the computer measures the boot path andsaves collected metrics to PCR5 (a register in the Embedded Security Device). Bitlocker trackschanges to any of these metrics, and forces the user to re-authenticate if it detects anychanges. Enabling this feature lets you set Bitlocker to ignore detected changes to boot pathmetrics, thereby avoiding re-authentication issues associated with USB keys inserted in a port.Default is enabled.

OS management of Embedded Security Device (enable/disable) - This option allows the user to limitOS control of the Embedded Security Device. Default is enabled. This option is automaticallydisabled if Trusted Execution Technology is enabled.

  • Reset of Embedded Security Device through OS (enable/disable) - This option allows the userto limit the operating system ability to request a Reset to Factory Settings of the EmbeddedSecurity Device. Default is disabled.


    To enable this option, a Setup password must be set.

  • No PPI provisioning (Windows 8 only) - This option lets to set Windows 8 to bypass the PPI(Physical Presence Interface) requirement and directly enable and take ownership of the TPMon first boot. End-user cannot change this setting after TPM is owned/initialized, unless the TPM isreset. Default is disabled for non-Windows 8 systems, and enabled for Windows 8.

  • Allow PPI policy to be changed by OS. Enabling this option allows the operating system toexecute TPM operations without Physical Presence Interface. Default is disabled.


To enable this option, a Setup password must be set.

DriveLock Security

Allows to assign or modify a master or user password for hard drives. When this feature isenabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither issuccessfully entered, the hard drive will remain inaccessible until one of the passwords issuccessfully provided during a subsequent cold-boot sequence.


This selection will only appear when at least one drive that supports the DriveLock featureis attached to the system.

Secure BootConfiguration

This is a feature of Windows 8.

  • Legacy Support - Enable/Disable. Allows to turn Off all legacy support on the computer,including booting to DOS, running legacy graphics cards, booting to legacy devices, and soon. If set to disable, legacy boot options in Storage > Boot Order are not displayed.Default is enabled.

  • Secure Boot - Enable/Disable. Allows to make sure an operating system is legitimatebefore booting to it, making Windows resistant to malicious modification from preboot to fullOS booting, preventing firmware attacks. UEFI and Windows Secure Boot only allow codesigned by pre-approved digital certificates to run during the firmware and OS boot process.Default is disabled, except for Windows 8 systems which have this setting enabled. SecureBoot enabled also sets Legacy Support to disabled.

  • Key Management - This option lets to manage the custom key settings.

    • Clear Secure Boot Keys - Do not Clear/Clear. Allows to delete any previously loadedcustom boot keys. Default is Don't Clear.

    • Key Ownership - HP Keys/Custom Keys. Selecting Custom Mode allows to modifythe contents of the secure boot signature databases and the platform key (PK) that verifieskernels during system start up, allowing to use alternative operating systems.

    Selecting HP Keys causes the computer boot using the preloaded HP-specific boot keys.Default is HP Keys.

  • Fast Boot - Enable/Disable. Fast boot disables the ability to interrupt boot, such as pressing fkeys to access items before the operating system loads. Default is disabled.


    If Windows 8 detects a serious error, it will interrupt the boot process automaticallyand display advanced boot options.

    • FullBoot = Memory test (count) on cold boot. Clears memory on all boots.

    • Clear Memory = No memory count on cold boot. Clears memory on all boots.

    • FullBoot Every x Days = Memory count on 1st cold boot on or after the xth day. No morememory counts until 1st cold boot on or after x days. Clears memory on all boots.

  • POST messages (enable/disable). Enabling this feature will cause the system to display POSTerror messages, which are error messages displayed on the monitor during the Power On SelfTest if the BIOS encounters some kind of problem while starting the PC. A POST error messagewill only display on screen if the computer is capable of booting this far. If the POST detectsan error before this point, a beep code is generated instead. Default is disabled.

  • Press the ESC key for Startup Menu (Enable/Disable). This feature controls the display of thetext “Press the ESC key for Startup Menu” during POST. This text does not display onWindows 8 systems with Fast Boot support. Other text also will not display (for example,Ownership Tag). Default is enabled.

  • Option ROM Prompt (enable/disable). Enabling this feature will cause the system to display amessage before loading option ROMs. Default is enabled.

  • After Power Loss (Off/On/previous state). Default is Power off. Setting this option to:

    • Power Off - causes the computer to remain powered off when power is restored.

    • Power On - causes the computer to power On automatically as soon as power is restored.

    • Previous state - causes the computer to power On automatically as soon as power isrestored, if it was On when power was lost.


If you turn off power to the computer using the switch on a power strip, you will not beable to use the suspend/sleep feature or the Remote Management features.

  • POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POSTprocess. This delay is sometimes needed for hard disks on some PCI cards that spin up veryslowly, so slowly that they are not ready to boot by the time POST is finished. The POST delayalso gives you more time to select F10 to enter Computer (F10) Setup. Default is None.
  • Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.
  • Factory Recovery Boot Support (Enable/Disable). Provides the ability for the BIOS to redirectthe boot to the recovery partition on the user hard drive, if present. Some versions of therecovery software honor the F11 key press even when this feature is disabled by the BIOS.Default is disabled.
  • Bypass F1 Prompt on Configuration Changes (Enable/Disable). Allows to set the computernot to confirm when changes were made. Default is disabled.

BIOS Power-On

Allows to set the computer to turn On automatically at a specified time.

Onboard Devices

Allows to set resources for or disable Legacy devices.

Select the Legacy device's IRQ, DMA, and I/O Range. The settings may not take effect for alloperating systems. To hide a device from the operating system, see Security > Device Security.

Device Options

Allows to set:

  • Printer mode (Bi-Directional, EPP + ECP, Output Only). ECP = Enhanced Capabilities Port, EPP= Enhanced Parallel Port. Default is EPP+ECP.

  • Integrated Video (enable/disable). Use this option to disable the integrated video controllerwhen another video controller is present in the system. Default is enabled.

  • Integrated Graphics (Auto/Disable/Force) Use this option to manage integrated (UMA)graphics memory allocation. The value the end-user chooses is allocated permanently to graphics and isunavailable to the operating system. For example, if the end-user sets this value to 512M on a systemwith 2GB of RAM, the system always allocates 512MB for graphics and the other 1.5GB foruse by the BIOS and operating system. Default is Auto which sets memory allocation to 512MB.If the end-user selects Force, the UMA Frame Buffer Size option displays, which lets the end-user to set the UMAmemory size allocation between 32MB and 1GB.

  • Internal speaker (does not affect external speakers). Default is enabled.

  • NIC PXE Option ROM Download (PXE, iSCSI, disabled). The BIOS contains an embeddedNIC option ROM to allow the unit to boot through the network to a PXE server. This is typicallyused to download a corporate image to a hard drive. The NIC option ROM takes up memoryspace below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This spaceis limited. This F10 option will allow users to disable the downloading of this embedded NICoption ROM thus giving more DCH space for additional PCI cards which may need optionROM space. The default will be to have the NIC option-ROM-enabled. Default is PXE.

  • SATA RAID Option ROM Download (enable/disable). The BIOS contains an embedded SATARAID option ROM for RAID support. This can be temporarily disabled to save DCH space.Note that with the option ROM disabled, users will be unable to boot to hard drives in thesystem while running in RAID mode. Default is disabled.

AMT Configuration

Allows to set:

  • AMT (enable/disable). Allows to enable or disable functions of the embeddedManagement Engine (ME) such as Active Management Technology (AMT). If set to disable, theManagement Engine is set to a temporarily disabled state and will not provide functionsbeyond necessary system configuration. Default is enabled.

  • Unconfigure AMT/ME (enable/disable). Allows to unconfigure any provisionedmanagement settings for AMT. The AMT settings are restored to factory defaults. This featureshould be used with caution as AMT will not be able to provide any set AMT managementfunctions once unconfigured. Default is disabled.

  • Hide Unconfigure ME Confirmation Prompt (enable/disable). Allows to set the system tonot display the confirmation to unconfigure ME.

  • Watchdog Timer (enable/disable). Allows to set amount of time for a operating systemand BIOS watchdog alert to be sent if the timers are not deactivated. BIOS watchdog isdeactivated by BIOS and would indicate that a halt occurred during execution if the alert issent to the management console. An operating system alert is deactivated by the operatingsystem image and would indicate that a hang occurred during its initialization. Default isenabled.
