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.

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,
