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 there is no error message, go to Procedure 2.
If the Toshiba MS-DOS is properly loaded, go to Procedure 3.

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
