Memory Check

Use this option to check the computer’s built-in memory. The

program checks only the amount of memory that you have

indicated as present in the Setup program.

For this check, the program writes specific data into memory

and then reads it back. The data is written and read in blocks

of 64KB. A parity check is also made on each block. A count of

memory is displayed after each block that is tested without an

error. The final message is usually:

640 KB OK

If an error is reported, write down the error code and message,

or print them out, and contact your Customer Care Center.

Attempting to correct memory errors yourself may violate your

warranty agreement.

Keyboard Check

Use this option to check the operation of the keyboard. The

program first checks the keyboard controller; during this check,

you see the green indicator lights on the keyboard flash. If no

errors are detected, you can then choose the correct keyboard

layout.

If you run the keyboard check multiple times, the KEYBOARD

SELECT MENU does not appear.

Before checking the operation of the keys, you must select the

appropriate keyboard layout so that the test display matches

the keys on your keyboard. You see the following menu.

1 2 ... 167 168 169 170 171 172 173 174 175 176 177 ... 250 251
