Recovering your operating system and preinstalled software
This section contains instructions for recovering BIOS code, device drivers,
operating system, and other support software.
Notes:
1. The Product Recovery program is provided on your computer to assist you
with recovery operations.
2. The Product Recovery program is preinstalled on the hard disk drive that
comes with your IBM computer and is designed to be hidden from view to
protect the program from accidental damage.
If you are using fdisk, NT Disk Administrator, or another utility to reformat
your hard disk drive, you might be able to see the partition where the Product
Recovery program is stored. Do not delete this information, or your Product
Recovery program will be lost.
3. Some recovery processes delete all information stored on the primary partition
(drive C). If possible, back up your data files before starting the process.
Recovering BIOS
If the BIOS code has become corrupted, such as from a power failure during a
flash update, you can recover the BIOS code using the boot block jumper and a
BIOS flash diskette.
The boot block jumper selects between normal BIOS mode and flash recovery
mode. In the normal position, the jumper will be installed on pins 2 and 3. In the
recovery mode, the jumper will be installed on pins 1 and 2.
Note: You can obtain a BIOS flash diskette from one of the following sources:
v
Download files to make a BIOS flash diskette from the World Wide Web.
Go to http://www.pc.ibm.com/support/ and make the selections for
your computer.
v
Contact your IBM service representative.
Complete the following steps to recover the BIOS code.
1.
Remove any media (diskettes, CDs, or tapes) from the drives and shut down
your operating system.
2. Turn off the computer and all attached devices and disconnect all external
cables and power cords.
3.
If necessary, unlock the computer cover; then, remove the cover. For the tower
model, see “Removing the side cover” on page 45 and for the desktop model,
see “Removing the computer cover” on page 59.
