(WWAN), is a high-speed digital cellular network that provides Internet

access over a much wider geographical area than a WLAN, which typically

covers only from 100 to 1000 feet. Your computer can maintain Mobile

Broadband network access as long as the computer is within a cellular-data

coverage zone. Contact your service provider for coverage of a high-speed

digital cellular network.

Using Cards 89

Using a Hard Drive Password

The hard drive password helps protect the data on your hard drive from

unauthorized access. You can also assign a password for an external hard drive

(if one is being used) that can be the same as or different from the password

for the primary hard drive.

To assign or change a hard drive password, enter system setup (see "System

Setup Program" on page 123).

After assigning a hard drive password, you must enter it each time you turn on

the computer and each time you restore the computer to normal operation

from standby mode.

If the hard drive password is enabled, you must enter it each time you turn on

the computer: A message appears asking for the hard drive password.

To continue, enter your password (with no more than eight characters) and

press <Enter>.

If you do not enter a password within 2 minutes, the computer returns to its

previous operating state.

If you enter the wrong password, a message tells you that the password is

invalid. Press <Enter> to try again.

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 and Russia are not equipped with the TPM

feature.

96 Securing Your Computer

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
