4. If no keyboard keys are pressed, and if POST is completed
without errors, the system will then proceed with the loading
of DOS or other operating system from diskette drive A or a
hard disk drive or CD-ROM drive, depending on the options
selected in the Setup Utility.
If any errors are detected by POST, there will be an error
message accompanied with an error code shown on display
screen and a beep. See “Index of Symptoms, Messages,
Error Codes, or Beeps” on page 74 to find the most likely
cause and countermeasure.
Diagnostics Tools
IMPORTANT: This manual is intended to test the IBM Machine
Types 2169 European market only. Testing
devices which are not included with the original
product package, including other IBM products,
prototype cards, or modifying hardware settings
may give false errors and invalid system
responses. The diagnostics not specifically
made for this model may also report incorrect
errors and information.
The PC-Doctor diagnostics program, developed by Watergate
for IBM, is the primary method of testing the computer. You can
use it to test the IBM components of the system and some
external devices. The amount of time required to test
components depends on the number of components installed
and selected. The more devices you have attached to your
system and selected in PC-Doctor, the longer the testing will
take. PC-Doctor can be downloaded form the IBM web.
Performing a partial or full recovery
Attention:
The Product Recovery program on the hidden hard disk drive
partition will overwrite all files on the C:\ drive only. A full
recovery will restore the operating system, device drivers, and
applications. A partial recovery will restore your operating
system and device drivers without restoring applications.
To perform a recovery of the operating system, do the following:
1. If you do not have a CD, go to step 2. If you have a CD,
open the CD-ROM drive. Insert Product Recovery CD 1.
Close the drive.
2. If you can shut down your desktop normally, do so. If you
cannot shut down, proceed with the following steps
anyway.
