Service Information
This section contains the general checkout procedures,
related service procedures, Symptom-to-FRU indexes, and
parts listings for IBM Personal Computer 300/700 Series
(Type 62XX, 65XX, and 68XX) and the IntelliStation (Type
6888, 6889, 6893, 6898, and 6899) computers.
Note
This manual and the diagnostic tests are intended to
test
only IBM products. Non-IBM products of any kind
including adapter cards, accelerator boards, options,
or non-IBM devices, can give false errors and invalid
computer responses. If you remove a non-IBM device
and the symptom goes away, the problem is with the
device you removed.
 Copyright IBM Corp. 1996, 1997, 1998 1

General Checkout (Type 62XX, 65XX,
68XX)
This general checkout procedure is for Type 62XX, 65XX,
and 68XX computers.
If you are servicing a Type 6272 Model 88X, 89X, 90X,
91X, computer, see “General Checkout (Type 6272
Models 88X, 89X, 90X, 91X)” on page 5.
If you are servicing a Type 6275, 6285, 6561, 6591,
6862, 6889, 6892, or 6893 computer, see General
Checkout on page 14
If you are servicing a Type 6876 or Type 6886 Micro
Channel computer, see “General Checkout (Type 6876,
6886)” on page 17.
Attention
The drives in the computer you are servicing might
have been rearranged or the drive startup sequence
changed. Be extremely careful during write operations
such as copying, saving, or formatting. Data or
programs can be overwritten if you select an incorrect
drive.
Diagnostic error messages appear when a test program
finds a problem with a hardware option. For the test
programs to properly determine if a test Passed , Failed , or
Aborted , the test programs check the error-return code at
test completion. See “Return Codes” on page 214.
General error messages appear if a problem or conflict is
found by an application program, the operating system, or
both. For an explanation of these messages, refer to the
information supplied with that software package.
Notes
1. Before replacing any FRUs, ensure the latest
level of BIOS is installed on the system. A
down-level BIOS might cause false errors and
unnecessary replacement of the system board.
For more information on how to determine and
obtain the latest level BIOS, see “BIOS Levels”
on page 200.
2. If multiple error codes are displayed, diagnose
the first error code displayed.
3. If the computer hangs with a POST error, go to
“Symptom-to-FRU Index” on page 32.
4. If the computer hangs and no error is displayed,
go to “Undetermined Problem” on page 81.
5. If an installed device is not recognized by the
diagnostics program, that device might be
defective.

Starting IBM PC Enhanced Diagnostics
These steps show how to start the DOS based IBM PC
Enhanced Diagnostics from Windows 95, Windows NT,
and Windows 3.X.
1. Shut down Windows 95 or Windows NT and re-start
in DOS mode. If Windows 3.X is running, close
Windows.
2. At the command prompt type: CD IBMDIAG, then
press the Enter key.
Note
If an invalid directory message appears, IBM PC

the computer and go to Step 001 on page 5.
Service Information 9

3. Type: PCDR, then press the Enter key.
4. Follow the instructions on the screen to run the
diagnostics.
Note
Do not start the diagnostics in the DOS session
of Windows 95 or from a command prompt under
Windows NT. The system must be shut down
and restarted in DOS.
Starting diagnostics under Windows 95 and
Window NT: Use the Windows diagnostics version
only if you cannot run the IBM PC Enhanced Diagnostics
under DOS.
1. Select Start
2. Select Programs
3. Select PC-Doctor
4. Select PC-Doctor for Windows
Diagnostics on the RTC CD
The IBM PC Enhanced Diagnostics are shipped on the
RTC (Ready To Configure) CD. For Type 6272
Disketteless models, the customer has the responsibility to
make the diagnostics available either locally on the PC
hard disk or remotely through a server.
Remote Diagnostics
Some computers might not have diagnostics loaded onto
the local hard drive. If the computer you are servicing is
connected to a server and the server has the diagnostic
image, remote diagnostics can be run. (To use the
diagnostics from the RTC CD, a diskette must be made
from the diskette factory, then the diskette files are loaded
on the server). See the customer's System Administrator
for more information about remote diagnostics.
Remote diagnostics require:
Access to the network
System Administrator to download the diagnostics or
to execute remote diagnostics to the client computer.
