System Board Check
Use this option to check the operation of each major component on the
system board, including:
l
The 80286 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 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 dealer or Epson for customer service. Attempting
to correct system board errors yourself may violate your warranty agree-
ment.
Memory Check
Use
this option to check the memory installed in your computer,
including expansion memory. The program checks the internal jumpers to
determine the amount of main memory, and reads the CMOS RAM to find
the amount of expansion memory If any settings are incorrect, use Setup to
define the correct amount in CMOS RAM and adjust the jumpers on the
system memory card.
