POST Each time you turn on your computer, power-on self-test (POST) is automatically run. POST programs are stored in flash memory along with the BIOS and the Configuration/Setup Utility Program. Functions of POST are: Test the computer hardware and subsystems Update the computer configuration Load the BIOS into system memory Load the operating system into system memory Report problems While POST is running, the computer displays an IBM screen with several messages and prompts. A password prompt asks you for a password, if you have set a password with the Configuration/Setup Utility Program. Other prompts allow you to access the Configuration/Setup Utility Program or escape from POST. When POST is successfully completed, the computer proceeds to the first screen of your operating system or application program. If problems or configuration changes are found, POST displays error codes and messages. Refer to the problem-solving section of the PC 300GL User Guide for explanations of error messages and actions you can take to correct problems. Configuration/Setup Utility Program Most computer devices (storage devices, ports, adapters, and other optional features) have programmable settings. Your computer has a special type of nonvolatile memory (called CMOS) where it saves these settings. This memory is kept active by a battery so the settings are not lost when you turn off the computer. Each time you turn on the computer, a POST routine copies the configuration settings from memory to the various devices to get them ready for operation. If the battery fails, the settings in memory are lost, and the Configuration/Setup Utility Program automatically reconfigures built-in devices. When you add or remove hardware from your computer and restart the computer, the configuration settings must be updated. In most cases, the BIOS detects the change in hardware and automatically updates the configuration. In other cases, you might need to use the Configuration/Setup Utility Program to manually update the configuration. Either way, the computer displays a configuration-error message on the screen and gives you the option of accessing the Configuration/Setup Utility Program. You must enter the Configuration/Setup Utility Program and either save the automatic update or manually change the new configuration settings. For more information on using the Configuration/Setup Utility Program and saving configuration changes, see the PC 300GL User Guide. 40 Software

POST
Each time you turn on your computer,
power-on self-test (POST)
is automatically run.
POST
programs are stored in flash memory along with the BIOS and the Configuration/Setup
Utility Program.
Functions of POST are:
±
Test the computer hardware and subsystems
±
Update the computer configuration
±
Load the BIOS into system memory
±
Load the operating system into system memory
±
Report problems
While POST is running, the computer displays an IBM screen with several messages and
prompts.
A password prompt asks you for a password, if you have set a password with
the Configuration/Setup Utility Program.
Other prompts allow you to access the
Configuration/Setup Utility Program or escape from POST.
When POST is successfully
completed, the computer proceeds to the first screen of your operating system or application
program.
If problems or configuration changes are found, POST displays error codes and
messages.
Refer to the problem-solving section of the
PC 300GL User Guide
for explanations
of error messages and actions you can take to correct problems.
Configuration/Setup Utility Program
Most computer devices (storage devices, ports, adapters, and other optional features) have
programmable settings.
Your computer has a special type of nonvolatile memory (called
CMOS
) where it saves these settings.
This memory is kept active by a battery so the
settings are not lost when you turn off the computer.
Each time you turn on the computer,
a POST routine copies the configuration settings from memory to the various devices to get
them ready for operation.
If the battery fails, the settings in memory are lost, and the
Configuration/Setup Utility Program automatically reconfigures built-in devices.
When you add or remove hardware from your computer and restart the computer, the
configuration settings must be updated.
In most cases, the BIOS detects the change in
hardware and
automatically
updates the configuration.
In other cases, you might need to use
the Configuration/Setup Utility Program to
manually
update the configuration.
Either way,
the computer displays a configuration-error message on the screen and gives you the option
of accessing the Configuration/Setup Utility Program.
You must enter the
Configuration/Setup Utility Program and either
save
the automatic update or manually
change the new configuration settings.
For more information on using the
Configuration/Setup Utility Program and saving configuration changes, see the
PC 300GL
User Guide
