General Information 1-15

Proceed to the following for details on the parameters under each IDE drive
submenu.

Type

This item specifies the number of cylinders, heads, and sectors, and the size
of a particular IDE drive. If no information appears opposite the parameters,
there is no drive installed in that channel.

Hard Disk Block Mode

This function enhances disk performance depending on the hard disk in use.
BIOS automatically detects if your hard disk supports this feature.
Setting to Auto allows data transfer in blocks (multiple sectors) to increase the
data transfer rate. If your system does not boot after setting this parameter to
Auto, change the setting to Disabled. The default setting for this parameter is
Auto.

Advanced PIO Mode

The advanced PIO mode feature improves system performance by allowing
the use of faster hard disk drives. If your hard disk supports this feature, you
may set this parameter to Auto (default), Mode 0, Mode 1, Mode 2, Mode 3, or
Mode 4 depending on the hard disk requirements. See the documentation that
came with the hard disk.
If your hard disk does not support this function, set this parameter to Disabled.

Hard Disk Size > 528MB

This enhanced IDE feature works only under DOS and Windows
environments. If set to Auto, which is the default, BIOS allows you to use a
hard disk with a capacity of more than 528MB. This is made possible through
the Logical block address (LBA) mode translation. You may be required to set
this parameter to Disabled if you use other operating systems.
To prevent data loss, set this parameter to Auto if you are using a hard disk
with more than 528MB capacity that was previously configured through the
LBA mode. If you use a hard disk configured through the user-specific
cylinder-head-sector (CHS) mode, set this parameter to Disabled.

Hard Disk 32-bit Access

Setting this parameter to Enabled improves system performance by allowing
the use of the 32-bit hard disk access. This enhanced IDE feature only works
under DOS, Windows 3.x, Windows 98, and Novell NetWare. If your software
does not support this function, set this parameter to Disabled. The default
setting is Enabled.

NOTE:

Power Management Mode

When the Power Management Mode parameter is set to Enabled, you can
configure the different power saving timers to your desired settings. Setting
this parameter to Disabled deactivates the power management feature and all
the timers. The default setting is Enabled.

Power Switch< 4 sec.

When set to Suspend, this parameter adds the suspend function to the
system power button on the front panel. The suspend function allows you to
put the system into suspend mode by pressing the power button for less than
four seconds while the system is on. When this parameter is set to Power off,
the power button simply turns the system power on or off. This parameter is
set to Power off by default.

Modem Wake-Up on Ring

This parameter allows you to enable or disable the Modem Wake-Up on Ring
feature. When enabled and if the computer is in suspend, an incoming call
automatically resumes normal power on mode. When disabled, the system
does not return to the “normal on” state even if there is an incoming modem
access. The default setting is Enabled.

These Power Management settings do not work in Windows 98.
Use the Control Panel Power utility for Win98 Power
Management settings.

Onboard Floppy Disk Controller

This parameter allows you to enable or disable to onboard floppy disk
controller chipset. When set to Enabled, the controller enables the diskette
drive on your computer. When set to Disabled, the controller deactivates the
drive but simultaneously frees IRQ 6 which is normally assigned to the
diskette drive. You may then assign IRQ 6 to another device.

Onboard IDE Primary Channel

This parameter allows you to enable or disable the onboard IDE primary
channel controller. Setting this parameter to Enabled lets you use the primary
IDE connector (IDE 1) to connect up to two IDE drives. Setting to Disabled

General Information 1-19

deactivates IDE 1 but frees IRQ 14 for the use of other devices. The default
setting is Enabled.

Onboard IDE Secondary Channel

This parameter allows you to enable or disable the onboard IDE secondary
channel controller. Setting this parameter to Enabled lets you use the
secondary IDE connector (IDE 2) to connect up to two IDE drives. Setting to
Disabled deactivates IDE 2 but frees IRQ 15 for the use of other devices. The
default setting is Enabled.

Memory/Cache Options

The Memory/Cache Options menu allows you to configure the Level 1 and
Level 2 caches. Enabling the cache parameters optimize system
performance.
Some older applications, however, may not run properly with the caches
enabled. Set the parameters to Disabled when you run these applications.
Disabling the caches will degrade system performance.

PnP/PCI Options

The parameters in the PnP/PCI Options menu allow you to set the IRQ
assignments for your PCI devices.

PCI IRQ Setting

This parameter allows for automatic or manual configuration of PCI devices. If
you use Plug and Play devices, you can keep the default setting Auto. The
system then automatically configures the Plug and Play devices. If you install
non-Plug and Play adapter cards, set this parameter to Manual. This allows
you to assign resources to non-Plug and Play cards first.

PCI IRQ Sharing

When set to Yes, this parameter allows you to assign the same IRQ to more
than one PCI device installed in the system. When set to No, you must assign
different IRQs to the PCI devices. The default setting is Yes.

VGA Palette Snoop

The VGA palette snoop function allows the system to refresh all ISA and PCI
graphic adapters installed in the syste m. This is need ed if you inst all an
additional graphics overlay card such as an MPEG or an advanced 3D
graphics adapter. If the image on your monitor has problems after installing
such an adapter, set this parameter to Enabled. Otherwise, leave it to the
default Disabled to achieve better performance.

1-20

Plug and Play OS

When this parameter is set to Yes, BIOS initializes only Plug and Play boot
devices, then the Plug and Play operating system takes care of the other
devices. When set to No, BIOS initializes all Plug and Play boot and non-boot
devices.
Set this parameter to Yes if you are using the Windows 98 operating system.
Set to No if you run any other operating system. The default setting is Yes.

Reset Resource Assignments

Set this parameter to Yes to avoid IRQ conflict when installing non-Plug and
Play cards.
Before you install non-Plug and Play cards, set this parameter to Yes, exit
Setup and turn off the computer. This clears all resource assignments and
allows BIOS to reassign resources to all installed Plug and Play devices the
next time the system boots. After clearing the resource data, the parameter
resets to the default setting No.

at the top of the page, read them before you begin with the procedure.
Carefully read each step of the check procedure and perform the steps as
instructed. If you do not remember the location of a specific part or test point,
or an adjustment or removal procedure, see the chapter that contains that
information. Always return to the check procedure after you do this. In some
cases, you are referred to other check procedures to detect the cause of the

This is the entry point for all check procedures. The check proc edures use
failure symptoms, Power-On Self Test (POST) error codes, or beeps to help
determine the defective field replaceable unit (FRU). Follow the suggested
check procedures or use the diagnostics diskette to determine the problem
FRU.

IMPORTANT:

This book comes with a diagnostic program diskette. This diskette should be
used ONLY with
Computers. Do not use this diskette on other models.
POST error codes and error messages are displayed on the screen after the
IBM logo. A beep will precede each error code or message. Please refer to
“Index of Symptoms, Messages, Error Codes, or Beeps” on page 2-8 for
additional help.
All voltages in the check procedures are positive unle ss otherwise indicated.
Use frame ground for all voltage checks unless otherwise specified.

IMPORTANT:

Replace FRUs ONLY when it is determined that the error is
not a result of software, loose contacts, or dirty component surfaces.
Any FRU change should be verified by running a complete test
(“Diagnostics - All Tests” in PC-Doctor diagnostics program).

2153/2139 Service Level A (SL-A)

There is a Power Override switch located at the back of the
machine, just above the connector for the power cable. If the system
does not power on after pressing the power button, situated on the
front of the machine, please check the power cable and the Power
Override switch. If the Power Override switch is switched on, no
power is supplied to the system.

How to Use Error Messages:

combinations that occur to diagnose failures. If more than one failure occurs,
begin the diagnosis from the first failure that appeared. The cause of the first
failure can result in false messages, error codes, or beeps. If you did not
receive any messages, error codes, or beeps, see if the symptom is listed in
Table 2-2, "Error Symptoms List” on page 2-14.

ATTENTION:

POST:

On Self Test (POST). The machine performs the POST each time it is
powered on. Use this information throughout the diagnostic procedures. The
POST is a series of system checks and initializations that verify the correct
operation of the base system.
After a successful POST, the system attempts to load operating system. The
system can be customized for different startup (boot) methods by the BIOS
Setup Utility. See “Startup Options” on page 1-18.
The system's default startup sequence automatically looks for the operating
system files in the hard disk if these files are not found in the diskette.

NOTE:

Table 2-1 lists BIOS error codes, messages, and beeps to their possible
causes, table 2-2 lists error symptoms and their possible causes. The most
likely cause is listed first. Make sure you complete all items in the cause or
"Action/FRU" column. When servicing a system, always begin with "Start" on
page 2-3.

When you have deemed it necessary to replace a FRU, and
did so, you must run a total system check to ensure that no other
activity has been affected by the change. This system check can be
done through the diagnostics program (Select

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

3. If you did not receive any error message, look for a description of your
error symptoms in “Error Symptoms List” in table 2-2.

Check all power supply voltages, switch, and jumper settings before you
replace the system board. Also check the power supply voltages if you
have a “system no-power” condition. (See "Power Supply Cable
Connector Specifications" on page 5-15, "Machine Type 2153/K6 System

Check Procedures 2-23

Troubleshooting

Failing Parts or Assemblies:

a problem to one part or assembly. The last step of the specific check
procedure you are using indicates that a part or assembly is failing. You
should inspect the part or assembly before you decide to replace it. It might be
loose, dirty, or in need of a small repair. The check procedures might lead you
to two, or even three, possible failing parts or assemblies. The parts that might
be failing are listed in order of the most probable failure. Also, the FRU parts
are defined as replaced units and are not repaired in the field.

Measuring Voltages:

voltages on cable plugs and electronic board connectors. If you are asked to
measure voltage at several places on a plug or connector, a chart next to or
near the instruction indicates the number of the plug or connector, the pin
numbers you should measure, the signal name, and the correct voltage for the
condition you are measuring. Measure the voltage only at the pins listed in the
chart. Remember to set the meter on the correct scale and to put the meter
leads in the correct position for the voltage you are asked to measure.

NOTE:

Use frame ground as the ground reference. Attach the black (ground)
lead of meter to frame ground, except where specified otherwise.
