IBM 6587 - PC 350 - 16 MB RAM, User Manual

Page: 54 / 102

Configuration/Setup Utility program prompt appears in
the bottom-left corner of your screen.
Tip
Note: The amount of available memory shown might
be somewhat less than expected because of
basic input/output system (BIOS) shadowing in
random access memory (RAM).
If POST finishes without detecting any problems, a single
beep sounds. Then the first screen of your operating
system or application program appears.
If POST detects a problem, an error message appears on
your 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 turn on
the system.
POST Beep Codes
POST 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 POST. More than one
beep indicates that POST detects an error.
Tip
If your computer does not start when you press the
power switch, try the following:
Ÿ
Make sure all cables are securely connected to the
correct locations.
Ÿ
Check to see if the voltage-selection switch is set
to the correct position.
If the problem is not corrected, have your computer
serviced.
Diagnostic Programs
IBM provides programs for diagnosing software and
hardware problems.
QAPlus/WIN-WIN
QAPlus/WIN-WIN, a Windows program, is included in
preinstalled software. QAPlus/WIN-WIN provides an
effective tool for isolating software-related problems,
because it encompasses the entire operating system.
QAPlus/WIN-WIN gathers Windows-related information
and also does some hardware device testing.
QAPlus/PRO
QAPlus/PRO is a DOS diagnostic program that is
available to you either in preinstalled software or on a
