Epson Equity IIe, User Manual

Page: 195 / 276

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:
000640
KB 0K
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.
Extended memory, which is normally not available to
MS-DOS, is checked using the protected mode of the 80286
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.
Before checking the operation of the keys, you must identify
your keyboard layout so the test is appropriate for the keys on
your keyboard. A display appears, asking you to identify the
shape of your
Enter
key. Choose the shape that matches the
one on your keyboard, then press
Enter.
