Password considerations
If you are setting any of the various types of passwords on your computer, you
should read and understand the following information:
v If you type an incorrect password, you will see an error message. If you type an
incorrect password three consecutive times, you must turn the computer off and
start again.
v If you set both a User Password and an IDE Drive User Password to the same
string, you will be prompted for the password only once when you turn on your
computer.
v Do not move an internal IDE hard disk drive to another computer if an IDE
Drive User Password has been set unless that computer also supports the IDE
Drive User Password.
v If your computer is connected to a local area network (LAN), Wake on LAN will
not work unless both a User Password and an IDE Drive User Password are set
using the same password.
User Password
When a User Password is set, the user is prompted to type a valid password each
time the computer is turned on. The computer cannot be used until a valid
password is typed from the keyboard.
Administrator Password
Setting an Administrator Password deters unauthorized persons from changing
configuration settings. If you are responsible for maintaining the settings of several
computers, you might want to set an Administrator Password.
After you set an Administrator Password, a password prompt is displayed each
time you try to access the Setup Utility program.
If both the user and administrator passwords are set, you can type either
password. However, to change any configuration settings, you must use your
administrator password.
IDE Drive User Password
The IDE Drive User Password, used on some computers, is used to protect the
data on the IDE hard disk drive(s). When this password is set, you are prompted
to type a valid password before any hard disk drive can be used. This prompt is
displayed each time you turn on your computer. If your computer has multiple
hard disk drives, they all must use the same password.
Attention
If an IDE Drive User Password is set but the IDE Drive Master Password is
not set, there is no recovery in the event that the IDE Drive User Password is
lost or forgotten. The hard disk drive must be replaced. See “IDE Drive
Master Password.”
IDE Drive Master Password
The IDE Drive Master Password, used on some computers, is used to recover use
of the hard disk drive in the event that the IDE Drive User Password is lost or
forgotten. Only the person who knows the IDE Drive Master password can reset
the IDE Drive User Password.
