System Board Check
Use this option to check the operation of each major
component on the system board, including:
Cl The 80286 CPU chip
tl The system ROM
0 The real-time clock, CMOS RAM, and battery
tl The main integrated circuits.
The checks made on the 80286 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.
Memory Check
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 the Setup program (described in
Chapter 2) 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.
