Memory Check
Use this option to check all the memory currently installed in
your computer. The program reads the CMOS RAM to find the
total amount of memory. If any settings are incorrect, run the
Setup program (described in Chapter 2) to automatically set the
correct amount of memory in CMOS RAM. If you installed an
optional memory card, you may need to adjust some DIP switch
settings on the card.
For this check, the program writes specific data into memory
and then reads it back in blocks of 64KB. It also makes a parity
check on each block. A memory count is displayed after each
block is tested without error. After the program checks the last
block, you see a message such as the following:
001024
KB OK
If an error occurs, make a copy or a printout of the error code
and message, and contact your Epson dealer or service center.
Attempting to correct memory errors yourself may violate your
warranty agreement.
Note
Extended memory, which is normally not available to
MS-DOS, is checked using the protected mode of the
80386SX CPU chip.
Keyboard Check
Use this option to check the operation and the configuration of
the keyboard. The program first checks the keyboard controller;
during this check, you see the green indicator lights on the
keyboard flash.
