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.

Error Message
Description
Software Generated Error Messages
Displayed 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.
Multiple Messages
The first error that occurs can cause additional errors. Follow the suggested action of the first error displayed. In this case, the system displays more than one error message. Always follow the suggested action instructions for the
first
error message
displayed.
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
Enter Select an item, run the test module, or run
the test
Down Arrow (↓)
Moves the cursor down
Up Arrow (↑)
Moves the cursor up
F1 Calls up the appropriate Help information.
Use the up arrow key (↑) or the down arrow key (↓) to scroll through the information. Pressing F1 from within a Help screen provides a help index from which you can select different categories. One of the important help categories is function key usage. Pressing Esc exits Help and returns to where you left off.
Esc Go back to the previous menu
Keys Action Tab Move to test group (or move to parameters)
6 PC 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.
8 PC 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.

Configuration
Note
DASD and other adapters may require additional configuration information.
Configuration is the allocation of the server resources to organize and interconnect hardware devices and software programs. The steps required to configure the server depend on the number and variety of devices and programs installed.
The PC Server 325 Type 8639 supports the following types of adapters.
Peripheral Component Interconnect (PCI) Extended Industry Standard Architecture (EISA) Industry Standard Architecture (ISA)
The following hardware configuration utility programs are supplied with the server.
Built-in Configuration/Setup program
Configures system board functions, such as the serial and parallel port assignments. It also allows you to set passwords for starting up and accessing the Setup program, and allows IRQ assignments of PCI devices.
PC Server 325 EISA Configuration Diskette
Configures EISA and ISA adapters.
Built-in SCSISelect Utility program
Configures SCSI devices. You can use SCSISelect to change default values, resolve configuration conflicts, and perform a low-level format on SCSI hard disk drives.
PC Server Utilities diskette
Use the PC Server Utilities diskette to backup and restore the CMOS and NVRAM configuration data.
Adapters:
Adding an adapter, such as a communication or audio adapter, extends the capabilities and power of the server. For example, a RAID (redundant array of independent disks) adapter can enhance logical-drive capacity and performance, and continue operation after a hard-disk drive failure. Up to six adapters can be installed in the connectors on the system board
Adapter Considerations:
Three types of adapters are available for the PC Server 325:
PCI adapters EISA adapters ISA adapters
22 PC Server HMM
The system board in the server contains one 32-bit, EISA/ISA-bus expansion slot and one 32-bit PCI-bus expansion slot. The remaining slots are shared PCI/EISA slots. The server supports only 5.0-volt adapters on the PCI bus.
High-performance PCI adapters, such as RAID adapters, are installed in the two PCI slots closest to the processor board. See “Expansion Slots” on page 93 and “System Board” on page 103.
Attention
To avoid possible damage to adapters and server components, be sure the adapters do not touch each other or the other components (such as the microprocessor) inside the server.
Assigning Interrupt Levels:
A rotational interrupt technique is used to configure PCI adapters. This technique enables the installation of PCI adapters that currently do not support sharing of PCI interrupts.
Always use the IBM PC Server EISA Configuration Diskette for the system you are servicing when assigning interrupts for EISA and ISA adapters. You cannot assign an EISA or ISA adapter the same interrupt that you have assigned to a PCI adapter. This is because the server does not support interrupt sharing among PCI, EISA, and ISA adapters.
If a situation occurs where you need an additional interrupt, you can use an interrupt from another function that you might not need, such as COM2 (Interrupt 3) or parallel port (Interrupt 5 or 7).
EISA Configuration Diskette:
You must use the EISA Configuration Diskette anytime you want to change resource allocations, such as:
Adding or removing devices Moving devices
Changing device function Resolving conflicts
Adding or removing EISA or ISA adapters In addition, if you disable the serial, parallel, infrared, or
diskette drive in the Configuration/Setup utility programs, you might need to run the EISA Configuration Diskette and make the same change. Refer to the README file on the EISA Configuration Diskette for more information.
Each time you use the EISA Configuration Diskette to configure the server, the configuration information is saved in a
System Configuration Information (SCI)
file and in the
NVRAM configuration. Only devices that you install and
PC Server 325 - Type 8639
23
configure correctly appear on the EISA Configuration screens.
Backing Up the EISA Configuration Diskette:
Use an operating system command, such as the DOS DISKCOPY command, to make a
complete
backup copy of the EISA Configuration Diskette. Using the backup copy can prevent damage to the original diskette. The operating system documentation provides information on backing up diskettes.
EISA Configuration Menu Selections:
When you start the EISA Configuration Diskette, an introductory screen appears. Press Y at the prompt. After you press Enter, the main menu, Steps in configuring the computer, appears. The EISA Configuration program main menu contains five steps:
Step 1: Important EISA configuration information
This step provides information about the differences between the ISA configuration process and the EISA configuration process.
Step 2: Add or remove boards
If the server is configured correctly, this step provides a list of the devices installed in the expansion slots. The Add choice allows you to add ISA devices to the configuration. If EISA adapters are installed in the server, and you have not copied the
.CFG
file to the EISA Configuration Diskette, you are prompted to insert the adapter's configuration diskette into the diskette drive. The
.CFG
file
is copied to the diskette. If the adapter's
.CFG
file is copied to the EISA Configuration Diskette before starting the diskette, and the adapter is installed in the server, EISA devices are added automatically.
Step 3: View or edit details
After adding EISA or ISA adapters in Step 2, use the Edit selection of this step to configure them. Use the Edit Resources selection of this step for complex configurations. If you change a setting in this step, you might have to change a switch or jumper setting on the system board or on a device.
Note
You can view the settings for PCI devices, but you cannot change them through the EISA Configuration utility program. To change settings for PCI devices, see “PCI Bus Control” on page 34.
Step 4: Examine switches or print report
After Steps 1 and 2 have been completed correctly, this step displays the correct switch and jumper settings for the
24 PC Server HMM
installed devices that have switches and jumpers. Also, you can choose to print a system configuration report.
Step 5: Save and exit
This step allows you to save the configuration or to discard the changes before exiting the program.
Use the Up Arrow (↑) or Down Arrow (↓) key to highlight your selection, then press Enter to make your selection. To help you track your progress, a checkmark (√) appears on the main menu next to the completed steps.
You can access help information through:
Help windows, which remain active. Information windows, which appear automatically as a
result of some configuration activities.
The Help=F1 prompt, which allows you to access the
Help Menu for screens displaying the prompt. To remove the Help Menu, press Esc.
Recording EISA Configuration Settings:
Record the configuration settings you made in Step 3: View or edit details and Step 4: Examine switches or print report on a separate sheet and store it in a safe
place for future reference. If a printer is attached to the server, you can use the Print Screen key to print these settings. The settings are helpful when you install additional options. Also, record the new settings each time you make changes. Be sure to record the current configuration settings for the user.
Starting the EISA Configuration Diskette
Note
Use a backup copy of the EISA Configuration Diskette. (see “Backing Up the EISA Configuration Diskette” on page 24).
To start the EISA Configuration Diskette:
1. Insert the backup copy of the EISA Configuration Diskette into the diskette drive.
2. Power-on the computer, or if it is already on, shut down the operating system and restart the computer.
3. When the first screen appears, press Y and then, press Enter. Follow the instructions on the screen until the Steps in configuring the computer menu appears.
4. Use the Up Arrow (↑) or Down Arrow (↓) keys to advance through the items on the screen. Use the Tab key to select choices on the bottom of the screen Press the Esc key to return to a previous menu.
5. Press Enter to make a selection.
6. Follow the instructions on the screen to view or change (edit) the configuration information.
