General Checkout
This general checkout procedure is for computers that are
supported by the QAPlus/PRO Diagnostics test.
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 5.)
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. If multiple error codes are displayed, diagnose
the first error code displayed.
2. If the computer reports a POST error, go to the
“Symptom-to-FRU Index” on page 107.
3. If the computer hangs and no error is displayed,
go to “Undetermined Problems” on page 135.
4. If a device cannot be selected from the Module
Test menu, that device might be defective.

Diagnostics
The following tools are available to help identify and
resolve hardware-related problems:
Power-on self-test (POST)
POST Beep Codes
Test programs
Error messages
Diagnostics Diskette
Power-On Self-Test (POST)
Each time you power-on the system, it performs a series of
tests that check the operation of the system and some
options. This series of tests is called the power-on
self-test , or POST . POST does the following:
Checks some basic system-board operations
Checks the memory operation
Starts the video operation
Verifies that the diskette drives are working
Verifies that the hard disk drive is working
If the POST finishes without detecting any problems, a
single beep sounds and the first screen of the operating
system or application program appears.
If the POST detects a problem, an error message appears
on the screen. A single problem can cause several error
messages to appear. When you correct the cause of the
first error message, the other error messages probably will
not appear on the screen the next time you power-on the
system.
POST Beep Codes
The Power On Self-Test generates a beeping sound to
indicate successful completion of POST or to indicate that
the tests detect an error.
One beep and the appearance of text on the display
indicates successful completion of the POST. More than
one beep indicates that the POST detects an error.
Test Programs
The QAPlus/PRO test programs on the PC Server System
Board Diagnostic Diskette, developed by DiagSoft for
IBM, are the primary method of testing the PC Server. You
can use them to test the IBM components of the system
and some external devices. The amount of time required
to test all components depends on the number of
components. The more optional adapters and devices you
have attached to the system, the longer the testing takes.
Diagnostic programs from the QAPlus/PRO Main Menu
include the following features.

Return Codes
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. To register the test
properly in the test log, the test programs must generate
one of the following return codes:
Return
Code Description
0 Indicates that the device passed its test.
1 Indicated that the device failed its test.
2 or
greater Indicates that the test stopped or was aborted.
General Checkout/Diagnostics QAPlus/PRO 5

Using the Test Programs
The test programs provide advanced functions and utilities
for service or support professionals to troubleshoot even
the most difficult problems.
Program Navigation:
You can maneuver within the test programs by typing the
first letter of a menu choice, using the function keys, or
using command-line options.
Intruder Alert:
When you load QAPlus/PRO diagnostics, Intruder Alert
checks for damage to the Diagnostic Diskette. If a virus or
program alteration is detected, the diagnostic programs do
not load.
To suspend Intruder Alert and continue loading the
diagnostic programs, press Esc.
Using the First Letter of a Menu Choice
Throughout the test programs, pressing the first letter of an
option on a menu is the same as moving to that item with
the cursor and pressing Enter; however, this function is
not enabled on Test Group Screens.
Using the Function Keys
Use the following keys to maneuver throughout the test
programs:
Additional functions are available in the Test Module
Selection screen and the Test Group screen using the
following keys:
Keys Action

6PC Server HMM

Command Line Options
The following Command Line Options are available when
initially loading the diagnostic program from within its
directory of a DOS operating system. Loading
QAPlus/PRO from a DOS system command line allows
selected tests and options to run with minimum memory.
At a DOS operating system prompt, where the
QAPlus/PRO files reside, type QAPLPRO /XXX (where
XXX represents one or more of the following from the list
below) then, press Enter.
Keys Action
Spacebar Toggle modules on/off (or toggle tests on/off)
F2 View test results log
F10 Local menu
+Next logical unit number (for example, LUN 1,
LUN 2, and so on)
−Previous logical unit number
Command Action
/B&W The /B&W command line option forces the
program to load in Black and White
(Monochrome) mode, which is often more
readable on laptop computers.
/LOG=file The /LOG=file command line option directs
the test programs to start using a specified
Error Log file.
/INT10 The /INT10 command line option forces the
test programs to use the BIOS for screen
writes.
/OXXX The /OXXX command line option, where
XXX=test group (for example, MBD, MEM,
VID, HDU, FDU, KBD, COM, LPT, and so
on), omits the designated test group from
loading.
/OALL The /OALL command line option omits all
test groups from loading. This command
can be used in conjunction with the /IXXX
command.
/IXXX The /IXXX command line option, where
XXX=test group (for example, MBD, MEM,
VID, HDU, FDU, KBD, COM, LPT, and so
on), loads the designated test group for
testing. This option is helpful if you have
insufficient memory available to load all of
the test programs simultaneously.
/USRCONFIG
=file The /USERCONFIG=file command line option tells the test programs to look for a
user diagnostic configuration file other than
the default USERDIAG.CFG.
General Checkout/Diagnostics QAPlus/PRO 7

Viewing the Test Groups
As you move the cursor bar up or down in the Test Module
Selection window, the right hand screen changes to show
the attributes, parameters, and the selected tests of the
corresponding Test Group. The diamond “♦” mark
indicates a module selected for testing.
The indicated attributes are characteristics of the selected
test module that are used by the test programs to
determine which tests to run or how to run selected tests.
Attributes are also used to limit the allowable range of
parameters (for example, – ending cylinder).
Parameters are values you select to establish the scope of
tests. For example, you can select Extended Memory
testing parameters and limit the testing to a specific range
of test blocks by specifying the starting and ending
memory block. This might be appropriate if prior
experience indicates that problems are likely to exist in a
specific area of memory. By selecting these limiting
parameters, you reduce memory testing time.
Scripting
Scripting allows you to select specific groups of tests,
testing parameters, and options. Your selection is saved
for later use as a test Script . To set up a test script, first
select all the appropriate test groups and specific tests you
want to run from the Module Testing section under
Diagnostics. You should also select appropriate testing
parameters and options. See “Program Navigation” on
page 6, for instructions to save a test script.
Changing Logical Unit Numbers
In some instances, you can have more than one logical
unit number (LUN) for a particular module. LUNs
represent individual devices within a test group or module.
For example, you might have two diskette drives or two
hard disk drives; or, you might have base and extended
memory installed in the computer. This configuration might
result in as many as two or three different LUNs in the
Memory Test Group.
Command Action
/SCRIPT
=file[,R] The /SCRIPT=file[,R] command line option with the “,R” runs the selected script.
Please see “Scripting” on page 8 for a
description of scripting.
Note
You can use a “–” instead of a “/” as
the command line switch.
8PC Server HMM

From either the Module Test Menu or the Test Group
window, you can change to a different LUN (where
applicable) by pressing the plus (+) key (next LUN), or the
minus (−) key (previous LUN).
Test Group Specifications
In the upper-right-hand portion of the testing screen (or just
the upper portion if you switched to an individual test group
screen) are the specifications for the related test group.
