NOTE: Compaq does not support mixing Ultra ATA and SCSI hard drives in the same system. If you are replacing a hard drive in bay 4 or 5, install the same type drive as you remove. If you are replacing the Ultra ATA hard drive in bay 4 or 5 with a SCSI hard drive, you will need a SCSI device option kit and the SCSI controller option kit. The controller option kit contains the SCSI controller and cable that supports multiple SCSI devices. See "Installing Optional SCSI Devices" later in this chapter for more information.
