Before Replacing 64XX System Boards

For all 64XX models, the processor is a separate FRU
from the system board; the processor is not included with
the system board FRU.

If you are instructed to replace the system board, do the
following:

1. Install the processor from the old system board on the
new system board.

2. If any of the following options are on the old system
board, install them on the new system board.

 external cache memory and cache tag RAM

 memory modules

 extended video memory

3. Ensure that all the new system board jumper settings
match the old system board jumper settings.

If the new system board does not correct the problem,
reinstall the options on the old system board, reinstall the
old system board, then replace the processor.

board and the processor will be damaged.

How to Diagnose 64XX system boards with
486DX4 Processors

The 486DX4 processor FRU consists of the processor and
a voltage regulator. If you are instructed to replace the
system board, first check for 3.5 V dc between pin 1 and
pin 19 on the regulator board.

19

1. If the voltage is correct (approximately 3.5 V dc)
replace the system board.

2. If the voltage is incorrect, replace the processor FRU.

Computer Memory

Four 72-pin connectors are available to add memory
modules. Memory modules supported are 4MB, 8MB,
16MB, and 32MB with a maximum of 128MB. Memory
module speed supported is 70 ns.

Notes:

1. QAPlus/WIN for ValuePoint and most applications do
not recognize more than 64MB of memory.

2. A memory module must be installed in memory
module connector 1 at all times. Additional memory
modules must be installed in connector 2, then in
connector 3, then in connector 4.

3. Smaller size memory modules must be installed into
lower numbered memory module connectors. For
example, to install two 4MB memory modules with
two 8MB memory modules, the 4MB memory
modules must be installed in memory module
connectors 1 and 2 and the 8MB memory modules in
memory module connectors 3 and 4.

Symptom-to-FRU Index

The Symptom-to-FRU Index lists error symptoms and
possible causes. The most likely cause is listed first.
Always begin with “General Checkout” on page 3 in this
supplement. This index can also be used to help you
decide which FRUs to have available when servicing a
computer. If you are unable to correct the problem using
this index, go to “Undetermined Problem” on page 5 in this
supplement.

Notes:

1. If you have both an error message and an incorrect
audio response, diagnose the error message first.

2. If you cannot run the diagnostic tests, but did receive
a POST error message, diagnose the POST error
message.

3. If you did not receive any error message, look for a
description of your error symptoms in the first part of
this index.

4. Check all power supply voltages before you replace
the system board. (See “Power Supply” on page 6 in
the PS/ValuePoint

5. Check the hard disk drive jumper settings before you
replace a hard disk drive. (See “Hard Disk Drive
Jumper Settings” on page 44 in this supplement.)

Important

1. For all 64XX models, some errors are indicated
with a series of beep codes (see “Model 64XX
Beep Code Index” on page 13 in this
supplement).

2. For all 64XX models, the processor is a separate
FRU from the system board; the processor is not
included with the system board FRU (see “Before
Replacing 64XX System Boards” on page 1 in
this supplement).

3. The 486DX4 processor FRU consists of the
processor and a voltage regulator. See “How to
Diagnose 64XX system boards with 486DX4
Processors” on page 2 in this supplement before
replacing the system board on models with this
processor installed.

Diagnostics and Test Information

The following information is helpful when diagnosing
computer problems on types 6472, 6482, 6484, 6492, and

6494.

Power-On Self Test

Each time you power-on the computer, the power-on self
test (POST) is initiated. The POST takes up to 90
seconds to complete, depending on the options installed.

The POST checks the following:
 System board

 Memory
 Video

 Hard disk drive(s)
 Diskette drive(s)
 Keyboard
 Mouse
 Parallel port
 Serial port(s)

To start the POST, power-on the display and the
computer. The following happens:

1. The following icon

appears at the upper-right corner of the display.
Pressing F1 at this time causes the Configuration
Utility menu to appear after the POST has completed.

2. A count of the computer memory appears at the
upper-left corner of the display.

Note: You can press Esc to speed through the

memory count during POST.

3. If an error is detected, an error code appears under
the computer memory count.

Note: Memory errors appear as 2XX in the

upper-left corner of the display
(X can be a number or letter).

4. Successful completion of POST is attained when
there are no errors detected in the computer.

5. The computer attempts to load the operating system.
If an operating system is not found, a graphic
message (icon) is displayed requesting the user to
insert a diskette into drive A and press the F1 key to
resume operation.

6. If a critical error is encountered, the POST is halted.

38 ValuePoint HMM - April 1994

Formatting a Hard Disk Drive: Hard disk drives

normally contain tracks in excess of their stated capacity to
allow for defective tracks. The user is notified by a
diagnostic message when the defect limit has been
reached and service is recommended.

The Diagnostics Format program is different from the
operating system format program. Before the customer
can transfer information from the backup diskettes to the
hard disk drive, the hard disk drive must be formatted
using the operating system format program. Have the
customer refer to the operating system manual for a
description of the hard disk preparation commands.

Note: The Diagnostics Format program on this diskette

might damage non-IBM hard disk drives. Refer to
the documentation that came with the drive for
low-level formatting information.

Warning: All data on the selected hard disk drive is
destroyed during a format operation or surface analysis.

Warning: Formatting results in a complete loss of data on
the hard disk drive, including system programs. If you are
directed to or elect to format the hard disk drive, prior to
formatting you must have the customer back up all
information, if possible.

Model 64XX Service Information 39

Formatting Procedure: Before replacing a failing

hard disk drive, try to format it as follows:

1. Power-off the computer. Check that the hard disk
drive cable is tightly connected.

2. Insert the diagnostics diskette into drive A.

3. Power-on the computer.

6. If the list is incorrect, run the Configuration Utility
program (see “Diagnostics and Test Information” on
page 32 in this supplement). Check to see if any
adapter or device is set to a conflicting address with
any other adapter or device. Also be sure that any
adapter or device missing from the list is not set to
“disabled.”
Press Y (Is this list correct? (Y/N)), then press
Enter.

7. Press 1 (Run tests ONE time), then press Enter.

8. Press 99 (Bypass ( ) all tests), then press Enter.

9. Select Hard Disk Drive, then press Enter. The Hard
Disk Drive test begins.
