Introduction
This section explains the diagnostic aids, power-on self test
(POST) and diagnostics program (PC-Doctor), 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. Several items are tested during POST, but
is for the most part transparent to the user.
POST checks the following:
•
System Board
•
Mouse
•
Memory
•
Parallel Port(s)
•
SVGA Controller
•
Serial Port(s)
•
Hard Disk Drive(s)
•
CD-ROM Drive(s)
•
Floppy Diskette Drive(s)
•
Sound Controller
•
Keyboard
To start POST, turn on the monitor and then the system unit.
The following will happen:
1. The IBM logo will appear on center of the screen.
2. At this time one of two hot-keys may be used. The F1 key,
as described on screen, will cause the system Setup Utility
menu to appear. The F9 key will switch the graphical IBM
logo screen to the traditional text-based system startup
screen, which displays BIOS version and system memory
tested.
3. If an error is detected during POST, the IBM logo screen
will automatically switch to the text-based screen and
display the error message or code with a beep. Depending
on the criticality of the POST error, the system may halt
and/or display the message “Press F1 to go to the Setup or
Enter to continue”.
If this message appears, pressing the Enter key will allow
the system to attempt to proceed despite the reported error;
pressing F1 will cause the system Setup Utility menu to
appear.
