Chapter 1. General checkout
This general checkout procedure is for type 6836, 6846 computers.
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
Chapter 3, “Diagnostics” on page 13.
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:
v Type 6836, 6846 computers default to come up quiet (no beep and no memory count and checkpoint code
display) when no errors are detected by POST.
v To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:
1. Select Start Options in the Configuration/Setup Utility program (see “Using the Configuration/Setup Utility
program” on page 23).
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. A down-level BIOS
might cause false errors and unnecessary replacement of the system board.
v If multiple error codes are displayed, diagnose the first error code displayed.
v If the computer hangs and no error is displayed, go to “Undetermined problems” on page 106.
v If an installed device is not recognized by the diagnostics program, that device might be defective.
001
1. Power-off the computer and all external devices.
2. Check all cables and power cords.
3. Make sure the system board is seated properly.
4. Set all display controls to the middle position.
If the Power Management feature is enabled, do the following:
1. Start the Configuration/Setup Utility program (see “Starting the
Configuration/Setup Utility program” on page 23.)
2. Select Power Management from the Configuration/Setup Utility program
menu.
3. Select APM.
4. Be sure APM BIOS Mode is set to Disabled. If it is not, press Left Arrow (})or
Right Arrow (Æ) to change the setting.
5. Select Automatic Hardware Power Management.
6. Set Automatic Hardware Power Management to Disabled.
7. If the problem persists, continue to 003.
003
Run the Diagnostic programs. If necessary, refer to “Starting the diagnostic
programs” on page 15.
v If you receive an error, replace the part that the diagnostic program calls out or
go to Chapter 3, “Diagnostics” on page 13.
v If the test stops and you cannot continue, replace the last device tested.

When you turn on the computer, it performs a series of tests to check the operation
of system components and some of the options that are installed in the computer.
This series of tests is called the power-on self-test or POST.
If POST finishes without detecting any problems, the first window of your
operating system or application program appears.
Notes:
1. If you have a power-on password set, you must type the password and press
Enter, when prompted, before POST will continue.
2. A single problem might cause several error messages. When this occurs, work
to correct the cause of the first error message. After you correct the cause of the

POST beep code descriptions
The possible types of beep codes that your system might emit are:
Repeating long beeps
Indicates that a memory error has occurred. Ensure that all DIMMs are
correctly installed.
One long beep and two short beeps
Indicates that a video error has occurred and the BIOS cannot initialize the
video screen to display any additional information. Ensure that the video
adapter is correctly installed.
Small computer system interface messages (some models)
The following table lists actions to take if you receive any error message.
Note: If your system does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
You will get these messages only when running the SCSISelect Utility.
AllOne or more of the following might be causing the problem.
v A failing SCSI device (adapter or drive)
v An improper SCSI configuration
v Duplicate SCSI IDs in the same SCSI chain
v An improperly installed SCSI terminator
v A defective SCSI terminator
v An improperly installed cable
v A defective cable
Action: Verify that:
v The external SCSI devices are turned on. External SCSI devices must be turned on before
the computer.
v The cables for all external SCSI devices are connected correctly.
v The last device in each SCSI chain is terminated properly.
v The SCSI devices are configured correctly.
If the above items are correct, run the diagnostic programs to obtain additional information
about the failing device.
IBM Enhanced Diagnostics
The system diagnostic programs are stored on the Device Drivers and IBM Enhanced
Diagnostics CD. These programs are the primary method of testing the major
components of your computer.
Diagnostic error messages indicate that a problem exists; they are not intended to
be used to identify a failing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.
Sometimes the first error to occur causes additional errors. In this case, the
computer displays more than one error message. Always follow the suggested
action instructions for the first error message that appears.
The following sections contain the error codes that might appear in the detailed
test log and summary log, when running the diagnostic programs.
The error code format is as follows:
fff-ttt-iii-date-cc-text message
where:
fffis the three-digit function code that indicates the function being tested
when the error occurred. For example, function code 089 is for the
microprocessor.
tttis the three-digit failure code that indicates the exact test failure that was
encountered. (These codes are for trained service personnel and are
described in the Hardware Maintenance Manual.)
iiiis the three-digit device ID. (These codes are for trained service personnel
and are described in the Hardware Maintenance Manual.)
14Hardware Maintenance Manual: IBM IntelliStation Type 6836, 6846
dateis the date that the diagnostic test was run and the error recorded.
ccare the check digits that are used to verify the validity of the information.
text message
is the diagnostic message that indicates the reason for the problem.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
is the name of the function being tested when the error occurred. This
corresponds to the function code (fff) given in the previous list.
Result can be one of the following:
Passed
Failed This result occurs when the diagnostic test discovers an error.
User Aborted
This result occurs when the diagnostic test completes without any
errors.
This result occurs when you stop the diagnostic test before it is
complete.
Not Applicable
This result occurs when you specify a diagnostic test for a device
that is not present.
Aborted
This result occurs when the test could not proceed because of the
system configuration.
Warning
This result occurs when a possible problem is reported during the
diagnostic test, such as when a device that is to be tested is not

Power and signal cables for internal drives
Your computer uses cables to connect IDE and SCSI drives to the power supply
and to the system board. The following cables are provided:
v Four-wire power cables connect the drives to the power supply. At the end of
these cables are plastic connectors that attach to different drives; these
connectors vary in size. Also, certain power cables attach to the system board.
v Flat signal cables, also called ribbon cables, connect IDE, SCSI, and diskette
drives to the system board. There are two sizes of ribbon signal cables that come
with your computer.
– The wider IDE signal cable has two or three connectors.
- If the cable has three connectors, one of these connectors is attached to the
drive, one is a spare, and the third attaches to the primary or secondary
IDE connector on the system board.
- If the cable has two connectors, one of these connectors is attached to the
hard disk drive, and the other attaches to the primary or secondary IDE
connector on the system board.
Notes:
1. If you want to add another device, and your computer does not come
with a CD-ROM drive preinstalled, you will need a second signal cable
with three connectors. You will need an 80-conductor ATA 66 signal
cable if you are replacing the existing signal cable or adding a second
hard disk drive. ATA 66 signal cables are color-coded. The blue
connector attaches to the system board; the black connector attaches to
the master device, and the gray middle connector attaches to the slave
device.
If your computer comes with a CD-ROM drive, it will have an ATA 66
signal cable. However, if you are installing a hard disk drive, you must
change the switch setting on the CD-ROM drive to secondary and
change the connector used for the CD-ROM drive to the gray middle
connector.
2. If you are installing a slimline CD-ROM drive in the small form factor
desktop model, the IDE cable requires a special connector to attach to
the slimline CD-ROM drive. This connector can be attached only to an
optional slimline CD-ROM drive.
– The narrower signal cable has two connectors, one to attach to the diskette
drive and the other to attach to the connector (FDD1) on the system board.
Note: To locate connectors on the system board, see “System board internal cable
connectors” on page 32.
The following are some important points to remember when connecting power and
signal cables to internal drives:
34Hardware Maintenance Manual: IBM IntelliStation Type 6836, 6846
v The drives that are preinstalled in your computer come with power and signal
cables attached. If you replace any drives, it is important to remember which
cable is attached to which drive.
v When you install a drive, ensure that the drive connector at the end of the signal
cable is always connected to a drive; also, ensure that the drive connector at the
other end is connected to the system board. This reduces electronic noise from
the computer.
v If two IDE devices are used on a single cable, one must be designated as the
primary or master device and the other as the secondary or subordinate device;
otherwise, some of the IDE devices might not be recognized by the system. The
primary and secondary designation is determined by switch or jumper settings
on each IDE device.
v If two IDE devices are on a single cable, and only one is a hard disk drive, the
hard disk drive must be set as the master device.
v If you have only one IDE device on a cable, it must be set as master.

Adapter considerations
Before you install adapters, review the following:
v Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this chapter. If you need to
change the switch or jumper settings on your adapter, follow the instructions
that come with the adapter.
v You can install full-length adapters in all PCI slots.
v Your computer supports 5.0 V and universal PCI adapters; it does not support
3.3 V adapters.
v Your computer uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
v PCI slots 1 through 3 are on PCI bus 0. The system scans the AGP slot and PCI
slots 1 through 3 to assign system resources; then, the system starts (boots) the
PCI devices in the following order, if you have not changed the default boot
sequence: PCI slots 1 and 2, system board integrated drive electronics (IDE) or
SCSI devices, and then PCI slot 3.
Note: To change the boot sequence for PCI devices, start the
Configuration/Setup Utility program, select Start Options from the main
menu, select Startup Sequence; then, select Second device (SCSI) to
designate the adapter boot sequence. See Chapter 4, “Configuration” on

Adapter considerations
Before you install adapters, review the following:
v Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this chapter. If you need to
change switch or jumper settings on your adapter, follow the instructions that
come with the adapter.
v You can install full-length adapters in all PCI expansion slots.
v Your computer supports 5.0 V and universal PCI adapters; it does not support
3.3 V adapters.
v Your computer uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
v PCI slots 1 through 5 are on PCI bus 0 . The system scans the AGP slot and PCI
slots 1 through 5 to assign system resources; then, the system starts (boots) the
PCI devices in the following order, if you have not changed the default boot
sequence : PCI slots 1 and 2, system board integrated drive electronics (IDE) or
SCSI devices, and then PCI slots 3 through 5.
Note: To change the boot sequence for PCI devices, start the
Configuration/Setup Utility program, select Start Options from the main
menu, select Startup Sequence; then, select Second device (SCSI) to
designate the adapter boot sequence. See Chapter 4, “Configuration” on
page 23 for details on using the Configuration/Setup Utility program.

Ultra 3/160 SCSI connector (some models)
Some IntelliStation xxxx E Pro computer models come with a SCSI adapter, which
supports an Ultra 3/160/MB SCSI internal channel in a full-featured PCI
2.1-/2.2-compliant bus master package. This configuration supports a zero wait
state, 32-bit memory transfers at 160 Mbytes/second, when LVD SCSI peripherals
are attached. This channel supports up to 15 SCSI devices. In addition, this adapter
uses:
v Double-transition clocking to achieve high transfer rates
66Hardware Maintenance Manual: IBM IntelliStation Type 6836, 6846
v Domain name validation to negotiate compatible data transfer speeds with each
device
v Cyclic-redundancy checking, instead of the usual parity checking, to significantly
improve data reliability
SCSI cabling requirements
You can install two internal SCSI devices using the SCSI signal cable that comes
with your computer. If you plan to attach external SCSI devices, you must order
additional SCSI cables. To select and order the correct cables for use with external
devices, contact your IBM reseller or IBM marketing representative. To receive
indication of SCSI hard-disk drive activity, you must also connect the SCSI adapter
to the SCSI LED (J3) connector on the system board. See “System and PCI extender
board options connectors” on page 32 for the location of the SCSI connector.
For information about the maximum length of a SCSI cable between the terminated
ends of the cable, refer to the American National Standards Institute (ANSI) SCSI
standards. Adhering to these standards will help ensure that your computer
operates correctly.
Setting SCSI IDs
Each SCSI device connected to a SCSI controller must have a unique SCSI ID. This
ID enables the SCSI controller to identify the device and ensure that different
devices on the same SCSI channel do not attempt to transfer data simultaneously.
SCSI devices that are connected to different SCSI channels can have duplicate SCSI
IDs.
To install external SCSI devices, you must first install an optional SCSI PCI
adapter. Refer to the information that is provided with the device for instructions
to set its SCSI ID.
With a SCSI adapter installed in your computer, you can use its 68-pin SCSI
connector to connect different types of SCSI devices.
