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 the Toshiba MS-DOS is properly loaded, go to Procedure 3.
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 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 system configuration in the
RTC memory configuration is set to the default setting. If error message (b) often
appears when the power is turned on, replace the RTC battery. If any other error
message is displayed, perform Check 2.
