Troubleshooting Procedures

2.4.1 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 MS-DOS or Windows OS is properly loaded, go to Procedure 4.
Check 1
If one of the following error messages is displayed on the screen, press the F1 key
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 the F1 key as the message instructs, the SETUP screen appears to set
the system configuration. If error message (b) appears often when the power is
turned on, replace the RTC battery. If any other error message is displayed,
perform Check 2.

If the following error message is displayed on the screen, press any key as the
message instructs.
