Power-On Diagnostics and Boot Errors The computer's ROM BIOS contains a series of diagnostic programs, called Rower-On Diagnostics (ROD). These programs check internal devices, such as ROM, RAM, the timer, the keyboard controller, and the hard disk drive every time you turn on the computer or reset the system. When the POD tests detect an error, the computer displays a message on the screen as described below. In some instances, the computer may also sound a beep. This happens when the error occurs before the computer initializes the video display. If the error is serious, the computer cancels further checking and halts system initialization. The error message remains on the screen and the computer locks up. Table 2-3 provides a list of the error messages that may appear. The solutions that are provided must be followed in order. If more than one replacement module is specified, replace them in order, one at a time. Table 2-3 Power-on Diagnostic Error Messages Epson NX Service Manual 2-3
