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.
With the two EIDE interface connectors on the system board, your
computer can support up to four EIDE drives:
The primary EIDE system-board connector should be cabled to EIDE
hard drives
The secondary EIDE connector should be cabled to EIDE CD, DVD,
tape, DAT, and zip drives
To locate the EIDE interface connectors on the system board, see "System
Board Components" or the interior service label. Each EIDE interface
connector on the system board supports the following:
To transfer data at full speed, Ultra ATA/100 hard drives require an 80-
conductor cable like that used with ATA/66 drives. 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
computers.
This section describes how to configure and install SCSI devices in your
computer. To install a SCSI device, you can use one or both of the following
SCSI controllers:
The SCSI connector on the system board. To locate the SCSI system
board connector, see "System Board Components" or the interior service
label.
NOTE: The system board SCSI controller will support hard drives only.
Do not connect CD or DVD drives, tape drives, DAT drives, and so on.
A SCSI controller card installed in your computer.
Internal SCSI devices must have a unique SCSI ID number from 0 to 15. If
you are using the SCSI connector on the system board and a SCSI
controller card installed in your computer, you will have two separate SCSI
buses operating. Each SCSI bus will have a set of SCSI ID numbers from 0
to 15.
When SCSI devices are shipped from Dell, the default SCSI ID numbers
for are assigned as follows:
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
computers.
SCSI logic requires that termination be enabled for the two devices at
opposite ends of the SCSI chain and disabled for all devices in between.
Dell recommends that you use terminated cables and that you disable
termination on all devices. See the documentation provided with any
optional SCSI device you purchase for information on disabling
termination on the device.
Follow these general guidelines when installing SCSI devices in your
computer:
Although you install SCSI devices essentially the same way as other
devices, their configuration requirements are different. For details on
configuring your particular SCSI subsystem, refer to the
documentation for your SCSI devices and/or your host adapter card.
Configure the device for a SCSI ID number and disable termination, if
necessary.
To use an external SCSI device, you must have a SCSI controller card
installed in your computer. Connect one end of the external SCSI
cable to the connector on the back of the SCSI device. Attach the
other end of the external SCSI cable to the connector on the controller
card installed in the computer.
After installing a SCSI hard drive, Primary Drive 0 and Primary Drive
1 should be set to None in system setup if no EIDE hard drives are
installed. If you have any EIDE devices on the second EIDE channel,
such as a CD or tape drive, Secondary Drive 0 and/or Secondary Drive
1 should be set to Auto.
You may need to use programs other than those provided with the
operating system to partition and format SCSI hard drives. Refer to
the documentation that came with your SCSI software drivers for
information on installing the appropriate drivers and preparing your
SCSI hard drive for use.
Ultra 160/m and Ultra2/Wide LVD drives (typically hard drives) both use a
68-pin cable. One end of the cable attaches to the SCSI connector on the
system board or the SCSI controller card installed in your computer. The
remaining connectors on the cable attach to the various drives.
Narrow SCSI drives (tape drives, CD drives, and some hard drives) use a
50-pin cable. One end of this cable attaches to the SCSI controller card.
The remaining connectors on the cable attach to the various Narrow SCSI
devices.
NOTICE: Dell recommends that you use only SCSI cables purchased from
Dell. Cables purchased elsewhere are not guaranteed to work with Dell
computers.
