You can install the Maxtor D540X-4K 20.4/40.0/60.0/80.0 GB AT hard disk
drives in an AT-compatible system that contains a 40-pin ATA bus connector on
the motherboard.
To connect the drive to the motherboard, use a 40 conductor ribbon cable (80
conductor ribbon cable if using UltraATA/66 drive) 18 inches in length or shorter.
Ensure that pin 1 of the drive is connected to pin 1 of the motherboard connector.

To install the Maxtor D540X-4K 20.4/40.0/60.0/80.0 GB AT hard disk drive in
an AT-compatible system without a 40-pin ATA bus connector on its motherboard,
you need a third-party IDE-compatible adapter board.

Carefully read the manual that accompanies your adapter board before installing it.
Make sure that all the jumpers are set properly and that there are no address or signal
conflicts. You must also investigate to see if your AT-compatible system contains a
combination floppy and hard disk controller board. If it does, you must disable the
hard disk drive controller functions on that controller board before proceeding.
Once you have disabled the hard disk drive controller functions on the floppy/hard
drive controller, install the adapter board. Again, make sure that you have set all
jumper straps on the adapter board to avoid addressing and signal conflicts.
Note: For Sections 3.7 and 3.8, power should be turned off on the
computer before installing the drive.
