2.4 System Board Troubleshooting
Procedure 1 Message Check
When the power is turned on, the system performs the Initial Reliability Test (IRT) installed
in the BIOS ROM. The IRT tests each IC on the system board and initializes it.
If an error message is shown on the display, perform Check 1.
If there is no error message, go to Procedure 2.
If DOS or Windows is properly loaded, go to Procedure 3.
Check 1 If one of the following error messages appears on the screen, press F1 as the
message instructs. These errors occur when the system configuration preserved in
the RTC memory (CMOS type memory) is not the same as the actual
configuration or when the data is lost.
If you press F1 as the message instructs, returns all system settings to their default
values. Then the system reboots.
If error message (b) appears often when the power is turned on, replace the RTC
battery. If any other error message displays, perform Check 2.
