Using the recovery-repair diskette
In some circumstances, files on your hard disk might become damaged so that the
F11 prompt is not displayed when you start your computer. If you have attached a
diskette drive to the computer and created a recovery-repair diskette, use the
following procedure to access the Product Recovery program on the hard disk. For
instructions to create a recovery-repair diskette, see “Creating an emergency
recovery-repair diskette” on page 18.
Complete the following steps to use the recovery-repair diskette:
1. Insert the recovery-repair diskette into the diskette drive.
2. Turn off your computer.
3. Turn on your computer, and follow the instructions on the screen.
If the repair operation is completed without error, the F11 prompt will be displayed
the next time you restart your computer.
If an error message is displayed during the repair operation and the repair operation
cannot be completed, you might have a problem with the Product Recovery
program or the partition that contains the Product Recovery program. Use a Product
Recovery CD to access the Product Recovery program. To obtain a Product
Recovery CD, contact IBM. See Appendix A, “Getting help and technical
assistance,” on page 113 for details.
Erasing a lost or forgotten password (clearing CMOS)
This section describes how to clear the CMOS to eliminate problems and erase a
forgotten password. If you experience severe problems with the computer and the
computer does not start, the code might be damaged. You might need to clear the
CMOS memory to recover. This procedure also erases the power-on password in
case it is lost or forgotten.
Complete the following steps to set the CMOS recovery jumper and erase a
forgotten password:
1. Read Appendix B, “Safety information,” on page 115, and the “Installation
guidelines” on page 29
2. Turn off the computer and all attached devices. See “Turning off the computer”
on page 6 for instructions.
3. Disconnect the power cord.
4. Remove the side cover (see “Removing the side cover” on page 32).
