v User HDP - for the user
v Master HDP - for the system administrator, who can use
it to get access to the hard disk even if the user has
changed the user HDP
Note: There are two modes for the HDP: User only and
Master + User. The Master + User mode requires
two HDPs and is designed for the system
administrator to input both in the same operation.
The system administrator then provides the user
HDP to the system user.
Attention:
If the user HDP is forgotten, check to see if a master HDP
was set. If a master HDP was set and can be recalled, this
will allow access to the hard-disk drive. If no master HDP
is available, IBM does not provide any services to reset
either the user or the master HDPs nor recover data from
the hard-disk drive. The hard-disk drive can be replaced
for a scheduled fee.
Supervisor password: A supervisor password (SVP)
protects the system information stored in the IBM BIOS
Setup Utility . The SVP must be entered in order to access
the IBM BIOS Setup Utility and make changes to system
configuration settings.
Attention:
If the SVP has been forgotten and cannot be made
available to the servicer, there is no service procedure to
reset the password. The system board must be replaced
for a scheduled fee.
How to remove the power-on password: To remove the
POP, do the following:
(A) If SVP is installed and known by the servicer
1. Power on the computer while pressing and holding F1.
2. Enter the supervisor password. The IBM BIOS Setup
Utility menu appears.
3. Select Password, using the cursor keys to move down
the menu.
4. Select Power-on password. A pop-up window opens.
5. Enter the password. When the Enter New Password
field opens, leave it blank and press Enter twice.
6. Press F10; then click Exit.
7. Select Yes in the Setup Configuration window. The
POP has been removed.
