Справочник Пользователя для Epson 20

The remainder of this chapter describes the tests you can run on the

system’s internal devices and on the optional devices installed on your
computer. The program displays the title of each check on the screen.

For a complete list of the error codes and messages these tests may

display, see the table at the end of this chapter.

Use this option to check the operation of each major component on

the system board, including:

l

The 80386 CPU chip

l 

The system ROM

l

The real-time clock, CMOS RAM, and battery

l

The main integrated circuits.

The checks made on the 80386 CPU chip are extremely

comprehensive and ensure that the CPU instruction set, including

protected-mode operation, is functioning correctly.

If an error occurs, make a copy or a printout of the error code and

message, and contact your Epson dealer or service center for
assistance. Attempting to correct system board errors yourself may

violate your warranty agreement.

Use this option to check the memory installed in your computer,

including expansion memory. The program reads the CMOS RAM
to find the total amount of memory. If any settings are incorrect, use
Setup to define the correct amount in CMOS RAM. If you installed
an optional memory card, you may need to adjust some DIP switch

settings on the card.
