Chapter 1. About this manual
This manual contains service and reference information for IBM
® computer Types
8127, 8183, 8184, 8320, 8416, 8417, 8418, 8419 and 8429.
This manual is divided into product service sections and arelated service section,
as follows:
vThe product service sections include procedures for isolating problems to aFRU,
aSymptom-to-FRU Index, additional service information and an illustrated parts
catalog.
vThe related service section includes safety notices and safety information, and
problem determination tips.
Note:
This manual is intended for trained servicers who are familiar with IBM Personal
Computer products. Use this manual along with advanced diagnostic tests to troubleshoot
problems effectively.
Before servicing an IBM product, be sure to review the “Safety information” on page 153.

Strategy for Replacing FRUs for CTO, CMV, and GAV products
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for acustomer to configure an IBM solution from
an eSite, and have this configuration sent to fulfillment, where it is built
and shipped directly to the customer. The machine label, PC Entitlement
Warehouse (PEW), eSupport, and the HMM will load these products as the
4-digit MT and 3-digit model, where model =’CTO’ (Example: 1829-CTO).
Custom Model Variant (CMV)
This is aunique configuration that has been negotiated between IBM and
the customer. Aunique 4-digit MT and 3-digit model is provided to the
customer to place orders (Example: 1829-W15). ACMV is aspecial bid
offering. Therefore, it is NOT generally announced.
2Hardware Maintenance Manual

vThe MTM portion of the machine label is the 4-digit MT and 3-digit
model, where model =’CTO’ (Example: 1829-CTO). The PRODUCT ID
portion of the machine label is the 4-digit MT and 3-digit CMV model
(Example: 1829-W15).
vThe PEW record is the 4-digit MT and 3-digit model, where model =
’CTO’ (Example: 1829-CTO).
veSupport will show both the CTO and CMV machine type models
(Example: 1829-CTO and 1829-W15 will be found on the eSupport site.)
vThe HMM will have the 4-digit MT and 3-digit CTO model only
(Example: 1829-CTO). Again, CMVs are custom models and are not
found in the HMM.
General Announce Variant (GAV)
This is astandard model (fixed configuration). GAVs are announced and
offered to all customers. The MTM portion of the machine label is a4-digit
MT and 3-digit model, where model =a“fixed model number”, not ’CTO’
(Example: 1829-F1U). Also, PEW, eSupport, and the HMM will list these
products under the same fixed model number.
FRU Identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support
CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.
Using PEW
vPEW is the primary source for identifying FRU part numbers and FRU
descriptions for the key commodities for CTO, CMV and GAV products at aMT
-serial number level. An example of key commodities are hard disk drives,
system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.
vRemember, All CTO and CMV products are loaded in PEW under the 4-digit
MT and 3-digit model, where model =’CTO’ (Example: 1829-CTO). GAVs are
loaded in PEW under the 4-digit MT and 3-digit model, where model =a“fixed
model number”, not ’CTO’ (Example: 1829-F1U).
vPEW can be accessed at the following Web site:
http://w3-3.ibm.com/pc/entitle
Click on MACHINE LOOKUP, followed by WARRANTY INFORMATION. Input
the MT and Serial number and the list of key commodities will be returned in
the PEW record under COMPONENT INFORMATION.
vBusiness Partners using Eclaim will access PEW when performing Entitlement
Lookup. Business Partners will enter Loc ID, MT and Serial, and the key
commodities will be returned in the Eclaim record under SYSTEM DETAILS.
vAuthorized IBM Business Partners can access Eclaim at the following Web site:
http://wca.eclaim.com
Using eSupport
For Key Commodities (Examples -hard disk drive, system board,
microprocessor, LCD, and memory)
veSupport can be used to view the list of key commodities built in aparticular
machine serial (this is the same record found in PEW).
veSupport can be accessed at the following Web site:
http://www.ibm.com/pc/support
vTo view the key commodities, click on PARTS INFORMATION, then PARTS
LOOKUP. Type in the model type and serial number. The key commodities will
be returned in the eSupport record under PARTS SHIPPED WITH YOUR
SYSTEM.
Chapter 1. About this manual 3

For the Remaining FRUs (the complete list of FRUs at the MT Model level)
veSupport can be used to view the complete list of FRUs for amachine type and
model.
vTo view the complete list of FRUs, type in the machine type and model
(Example: 1829-CTO) under QUICK PATH. Under ’View by Document Type’
select PARTS INFORMATION. Under ’Filter by Category’ select SERVICE
PARTS. Under ’Parts Information by Date’ select SYSTEM SERVICE PARTS. The
list of service parts by description, with applicable machine type model and FRU
will be displayed.
Using the HMM
vUse the HMM as aback-up to PEW and eSupport to view the complete list of
FRUs at the MT Model level.

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 atest program finds aproblem with a
hardware option. For the test programs to properly determine if atest Passed,Failed
or Aborted,the test programs check the error-return code at test completion. See
“Diagnostic error codes” on page 49.
General error messages appear if aproblem 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:
vThe default for this computer is to boot up quiet (no beep and no memory count and
checkpoint code display) when no errors are detected by POST.
vTo enable beep and memory count and checkpoint code display when asuccessful POST
occurs, do the following:
1. Select Start Options in the IBM Setup Utility program (see “Starting the IBM Setup
Utility program” on page 19).
2. Set Power-On Self-Test to Enhanced.
v
Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system.
Adown-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 147.
vIf multiple error codes are displayed, diagnose the first error code displayed.
vIf the computer hangs with aPOST error, go to Chapter 7, “Symptom-to-FRU Index,” on
page 47.
vIf the computer hangs and no error is displayed, go to “Undetermined problems” on
page 89.
vIf an installed device is not recognized by the diagnostics program, that device might be
defective.

selected tests in that category. See “Test selection.”
4. Using the cursor movement keys, highlight asingle test within atest category,
then press Enter.This will run only that test.
Press Esc at any time to stop the testing process.
Test results, (N/A, PASSED, FAILED, ABORTED), are displayed in the field beside
the test description and in the test log. See “Viewing the test log” on page 17.
Test selection
To select one or more tests, use the following procedure.
1. Open the corresponding test category.
2. Using the cursor movement keys, highlight the desired test.
3. Press the space bar.
Aselected test is marked by >>.Pressing the space bar again de-selects atest
and removes the chevron.
4. Repeat steps 2and 3above to select all desired tests.
Test results

vDeviceID:
Contains the component’s unit-ID which corresponds to either afixed disk
drive, removable media drive, serial or parallel port, processor, specific RIMM,
or adevice on the PCI bus.
vDate:
