Epson 486SX - Manual (Page 138)

Note
If you remove one IDE hard disk drive and are leaving
another one in the system, you must set the jumpers on
the remaining drive to indicate that you have only one
IDE drive installed. Remove the other drive following
steps 1 and 2, above; then see page 7-4 or the
documentation that came with your hard disk drive for
instructions on setting the jumpers.
3. If you removed your only IDE hard disk drive, remove the
hard disk drive cable from its connector on the main system
board. First remove the cable from the clasp on the left side
of the subassembly. Then disconnect the cable from the
main system board connector.

4. If you need to connect the drive cable on your remaining
drive, see “Connecting the Cables,” below.
Installing a Drive
Follow these steps to install a new drive (or reinstall a drive
you removed):
1. Position the drive so its mounting screw holes face the
outside of the drive bay and its power supply and drive
connectors face the front of the subassembly, as shown in
the following illustration. Then lower the drive into the bay.
