Securing Your Computer

91

If you do not enter the correct password in three attempts, the computer tries to

start from another bootable device if the

Boot First Device option in system

setup is set to allow start-up from another device. If the

Boot First Device

option is not set to allow the computer to start from another device, the

computer returns to the operating state it was in when you turned it on.
If the hard drive password, the external hard-drive password, and the primary

password are the same, the computer prompts you only for the primary

password. If the hard drive password is different from the primary password, the

computer prompts you for both. Two different passwords provide greater

security.

NOTE:

The administrator password provides access to the computer, but it does

not provide access to the hard drive when a hard drive password is assigned.

Trusted Platform Module (TPM)

NOTE:

Computers shipping into China are not equipped with the TPM feature.

NOTE:

The TPM feature may not be supported in all countries.

NOTE:

The TPM feature supports encryption only if the operating system supports

TPM. For more information, see the TPM software documentation and the help files

that came with the software.

TPM is a hardware-based security feature that can be used to create and manage

computer-generated encryption keys. When combined with security software,

the TPM enhances existing network and computer security by enabling features

such as file protection capabilities and protected e-mail. The TPM feature is

enabled through a system setup option.

NOTICE:

To secure your TPM data and encryption keys, follow the backup

procedures documented in the Broadcom Secure Foundation Getting Started
Guide

. In the event of these backups being incomplete, lost, or damaged, Dell will

be unable to assist in the recovery of encrypted data.

a

to enter the system setup program.
