In the mini tower chassis, you can install up to two EIDE drives (one of which must be 1 inch high or less) in the hard-disk drive bracket below the drive cage. The first EIDE drive is installed in the 1-inch (lower) drive bay labeled "HD1"; a second drive is installed in the 1.6-inch bay labeled "HD2." EIDE Drive Addressing All EIDE devices require that you configure the cable select setting, which assigns master and slave status to devices according to their position on the interface cable. You usually configure a drive for cable select by setting a jumper or switch, depending on the drive. Refer to the drive documentation in your upgrade kit for information on configuring devices for the cable select setting. When you connect two EIDE devices to a single EIDE interface cable and configure them for the cable select setting, the device attached to the last connector on the interface cable is the master or boot device (drive 0) and the device attached to the middle connector on the interface cable is the slave device (drive 1). With the two EIDE interface connectors on the system board, your system supports up to four EIDE devices in the mini tower chassis; the smallform-factor and low-profile chassis support up to two EIDE devices. EIDE hard-disk drives should be connected to the EIDE interface connector labeled "IDE1." (Always connect EIDE tape drives and CD-ROM drives to the EIDE interface connector labeled "IDE2.") Installing an EIDE Hard-Disk Drive in a Small-Form-Factor Chassis To install an EIDE hard-disk drive in a small-form-factor chassis, perform the following steps: CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from electrical outlets, and then wait at least 15 seconds before you remove the computer cover. Also, before you install a drive, see the other precautions in "Safety First - For You and Your Computer." 1. If you are replacing a hard-disk drive that contains data you want to keep, be sure to make a backup of your files before you continue this procedure. 2. Prepare the drive for installation. NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer. NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage the drive. Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it. Check the documentation for the drive to verify that it is configured for your computer system. 3. Remove the computer cover as instructed in "Removing and Replacing the Computer Cover." 4. Remove the drive shelf from the chassis. a. Disconnect the power and interface cables from the diskette drive and CD-ROM drive (if any). b. Press inward on the two drive shelf release tabs, and pull the shelf forward and out of the chassis (see Figure 1). Figure 1. Removing the Drive Shelf From the Small-Form-Factor Chassis
