Epson II+ Manuel D’Utilisation

If any additional memory (expansion RAM) is installed, the computer

then checks that RAM for any malfunction.

The computer checks its floppy disk drives by searching the read/write

heads for any malfunction.

If any seek errors are found, you see this message:

601-Diskette error

If this error occurs, confirm that the system diskette is inserted into drive A.

If this number still appears after you insert the diskette, the disk drive must

be repaired.

The computer next checks the hard disk controller and drive unit. If a

malfunction is found in the hard disk controller card, you see this error
number and message:

1782-Disk controller failure

If an error is found in the hard disk drive unit, one of these error mes-

sages displays:

178x-Disk x error

179x-Disk x error

where x is 0 or 1, and represents the drive number of the hard disk. Drive C
is number 0, and drive D is number 1.
