Backup files, remove cover, disconnect drive cables, remove old drive. Set jumpers and drive selection switches on new hard disk, install drive in bay and reconnect cables. Turn on computer, run setup, partition disk and format logical drives.
WARNING: Electrical shock hazard! Make sure the power is turned off and the external power cables have been disconnected before removing the computer cover.
CAUTION 1: This task should be performed by a qualified computer technician.
CAUTION 2: Please observe steps to reduce the potential damage to computer components from electrostatic discharge.
NOTE 1: Read the instruction manual that came with the IDE hard drive to determine whether the interface card bus type (ISA, EISA, VLB or PCI local bus) is compatible with the host computer.
NOTE 2: Refer to the computer and hard drive user manuals to compare the BIOS requirements of the new hard drive with the computer's BIOS specifications to make sure the new hard drive is compatible.
1) Save all files and close all applications if applicable.
2) Backup using DOS or backup using Windows 95 all desired application programs and data files on the hard drive using a network, tape backup unit, or diskettes if applicable.

4) Remove the computer cover.
5) Remove the existing IDE hard drive:
a) Disconnect the power and data cables.
b) Remove the screws holding the hard drive in its drive bay.
c) Slide the hard drive out of the bay and lift it out of the computer.
6) Check the drive select jumper on the hard drive, make sure the drive select jumper is set to one of the following:
a) If the hard drive is configured as the only device using the IIDE controller, the drive selection jumper should be left at the factory settings.
b) If the hard drive is configured as the second of two devices using the IIDE controller, the drive selection jumper must be set to 'Slave' if the other device is set to 'Master with Slave present'.
NOTE: If the other device is set to 'Slave', set the hard drive selection jumper to 'Master with Slave present'.
7) Insert the hard drive unit into an empty 3.5 inch or 5.25 inch bay, and secure the drive in the bay with four screws.
8) Connect the power cable to the drive unit.
9) Connect the internal IDE hard drive unit to the internal IDE adapter connector using the 40 pin ribbon cable.
10) Replace the computer cover, and connect the power cords.
11) If the new hard drive will not be used to boot the computer, turn on the computer, and do the following:
NOTE 1: Properly installed hard drives are auto-detected on IDE controllers during start-up.
NOTE 2: Typical installation errors are wrong jumper selections, loose connections or bad components. If the computer does not start normally, refer the problem to next-level support or a qualified computer technician.
