Introduction
This section explains the diagnostic aids that are available for
troubleshooting problems on the system.
Power-On Self Test
Each time you power-on the system, the power-on self test (POST) is
initiated. The POST takes up to 120 seconds to complete (with Power
Management disabled or not installed), depending on the options installed.
The POST checks the following:
System board
Memory
VGA
Hard disk drive(s)
Diskette drive(s)
Keyboard
Mouse
Parallel port
Serial port(s)
CD/DVD-ROM drive
Sound adapter card
To start the POST, turn on the monitor and the system unit. The following
happens:
1. The IBM APTIVA Logo appears on the monitor.
Pressing F1 at this time causes the Setup Utility menu to appear after
the POST has completed.
2. A count of the system memory appears at the upper-left corner of the
screen.
3. If an error is detected, an error code appears under the system memory
count.
Note: A memory error can appear without the memory count as:
XXXXXX XXXX 201, where the first six Xs = memory address,
the next four Xs = data.
4. Successful completion of POST is attained when there are no errors
detected in the system.
5. If a critical error is encountered, the system halts.
