15. Enter system setup, and update the drive settings.
After you update the system settings, exit system setup and reboot the computer.
16. Partition and logically format the drive before proceeding to the next step.
See the operating system's documentation for instructions.
17. Run the Dell Diagnostics to test the drive.
18. If the hard drive you installed is the primary drive, install the operating system on the drive.
See the operating system's documentation for instructions.

EIDE Device Installation Guidelines

Jumper Settings
All EIDE drives should be configured for the Cable Select jumper position, which assigns master and slave status to drives by their position on the interface
cable. When two EIDE drives are connected to a single EIDE interface cable and are configured for the Cable Select jumper position, the drive 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). Refer to the documentation in your drive upgrade kit for information on setting devices to the Cable Select jumper position.

General Guidelines

With the two EIDE interface connectors on the input/output (I/O) board, your system can support up to four EIDE drives:
The primary EIDE connector, labeled "IDE PRI," should be cabled to EIDE hard drives
l
The secondary EIDE connector, labeled "IDE SEC," should be cabled to EIDE CD, DVD, tape, SuperDisk, and Zip drives
l
NOTE: A SuperDisk drive is typically installed as the master device on the secondary EIDE system-board connector.
To locate the EIDE interface connectors on the system board, see
following:
Two channels, master and slave
l
Logical block addressing (LBA)
l
Programmed I/O (PIO) Mode 3 and Mode 4
l
Ultra Advanced Technology Attachment (ATA)/100, ATA/66, or ATA/33
l
EIDE Cables
Ultra ATA/66 and ATA/100 hard drives require an 80-conductor cable to transfer data at full speed. The 80-conductor cable has a 40-pin connector like the
ATA/33 cable, but it has twice as many wires within the cable. If you use an ATA/33 cable with Ultra ATA/100 hard drives, the drives will operate properly, but
data will transfer at ATA/33 speeds.
NOTICE: Dell recommends that you use only EIDE cables purchased from Dell. Cables purchased elsewhere are not guaranteed to work with Dell™
systems.

SCSI Device Installation Guidelines

This section describes how to configure and install SCSI devices in your system. To install a SCSI device, you must have a SCSI controller card installed in your
system.

SCSI ID Numbers

Internal SCSI devices must have a unique SCSI ID number from 0 to 15.
When SCSI devices are shipped from Dell, the default SCSI ID numbers for the primary and secondary controllers are assigned as follows:
SCSI controller: SCSI ID 7
l
Boot SCSI hard drive: SCSI ID 0
l
SCSI CD drive: SCSI ID 5
l
SCSI tape or digital audio tape (DAT) drive: SCSI ID 6
l
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.
SCSI devices installed by Dell are configured correctly during the manufacturing process. You do not need to set the SCSI ID for these SCSI devices.
If you attach additional optional SCSI devices, refer to the documentation for each device for information about setting the appropriate SCSI ID number.
NOTICE: Dell recommends that you use only SCSI cables purchased from Dell. Cables purchased elsewhere are not guaranteed to work with Dell
systems.
