How to remove the hard-disk password
Attention: If User only mode is selected and the user
HDP has been forgotten and cannot be made available to
the servicer, IBM does not provide any services to reset
the user HDPs or to recover data from the hard-disk drive.
The hard-disk drive can be replaced for a scheduled fee.
To remove a user HDP that has been forgotten, when the
SVP and the master HDP are known, do the following:
1. Power on the computer by pressing and holding F1.
2. Enter the SVP. The IBM BIOS Setup Utility menu
appears.
3. Select Password, using the cursor keys to move down
the menu.
4. Select Hard-disk x password, where x is the letter of
the hard-disk drive. A pop-up window opens.
5. Select Master HDP.
6. Enter the master HDP; then leave the New Password
field blank and press Enter twice.
7. Press F10.
8. Select Yes in the Setup Configuration window.
Both user HDP and master HDP will have been
removed.
