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.
