Epson equity ie q50188015-1 Manuel D’Utilisation

Use this option to check the operation of each major component on the

system board, including:

l

The 8086 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 8086 CPU chip are extremely comprehensive and

ensure that the CPU instruction set is functioning correctly. If an error

occurs, write down the error message, or print it out, and contact your

Epson dealer. Attempting to correct system board errors yourself may violate

your warranty agreement.

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

This option does not check expanded memory above the 640KB memory

limit imposed by MS-DOS.

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:

640KB OK

If an error occurs, write down the error message, or print it out, and contact

your Epson dealer. Attempting to correct memory errors yourself may
violate your warranty agreement.
