until the front-panel latches snap into the tabs on the front panel.
Your computer supports Rambus dynamic random-access memory
(RDRAM) Rambus in-line memory modules (RIMMs) in 64-, 128-, 256-,
and 512-megabyte (MB) capacities (see "Sample Memory Module
Configurations"). Each socket that does not contain a RIMM must contain
a Rambus continuity RIMM (CRIMM). To locate the RIMM sockets on the
system board, see "System Board Components."
When installing memory modules in the system board sockets, observe the
following guidelines:
To reach the maximum 2-gigabyte (GB) memory total, you must
install four 512-MB RIMMs that each have a maximum of 16 memory
devices. The system supports no more than a total of 64 memory
devices on all installed RIMMs.
See "RIMM Label" for the location of the label on a RIMM that
identifies the number of memory devices it contains. You can also
determine the number of memory devices installed through the
System Memory option in system setup.
NOTE: The computer does not support RIMMs with six memory devices.
Each RIMM socket must be occupied either by a RIMM or a CRIMM,
and must be upgraded in matched pairs of identical capacity in slots 1
and 2 or slots 3 and 4.
Mixed RIMM pairs provides a capacity equal to the sum of the four
RIMMs; mixed pairs of RIMMs that provide error checking and
correction (ECC) and non-ECC will all function as non-ECC.
Be sure to install a RIMM in socket 1 first (closest to the processor)
before installing modules in the other sockets.
The system board supports PC600 and PC800 memory modules.
PC700 memory is supported, but it will operate at PC600 speeds.
If necessary, remove any modules (RIMMs or CRIMMs) that occupy
sockets in which you plan to install the upgrade modules.
NOTE: The system supports no more than a total of 64 memory devices
on all installed RIMMs. See "RIMM Label" for the location of the label on
the RIMM that identifies the number of memory devices it contains. You
can also determine the number of memory devices installed through the
System Memory option in system setup.
Rotate the power supply back into position, making sure that the
securing tab snaps into place.
Replace the computer cover, reconnect the computer and peripherals
to their electrical outlets, and turn them on.
NOTE: If enabled, the Chassis Intrusion option will cause the following
message to be displayed at the next system start-up:
ALERT! Cover was previously removed.
The system detects that the new memory does not match the existing system configuration information and generates the following message:
The amount of system memory has changed. Strike the F1 key to continue, F2 to run the setup utility
Enter system setup, and check the value for System Memory. The
system should have already changed the value of System Memory to
reflect the newly installed memory. If the new total is correct, skip to
step 9.
If the memory total is incorrect, repeat step 1 and step 2. Check the
installed modules to ensure that they are seated properly in their
sockets. Then repeat step 5 through step 7.
When the System Memory total is correct, exit system setup.
Run the Dell Diagnostics to verify that the memory modules are
operating properly.
NOTICE: Before disconnecting a peripheral from the system or removing a
component from the system board, verify that the standby power indicator on
the system board has turned off. To locate this indicator, see "System Board
Components."
NOTICE: To avoid damage to the memory module, press the securing clips
with equal force applied at each end of the socket.
Press the securing clips at each end of the socket outward
simultaneously until the module pops out slightly from the socket (see
the following figure).
Lift the module away from the socket.
NOTE: If you remove a module (RIMM or CRIMM), you must install another
module in the empty socket before turning on the computer.

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 system
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, LS-120, and Zip drives
NOTE: An LS-120 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 "System
Board Components." Each EIDE interface connector on the system board
supports the following:
Two channels, master and slave
Logical block addressing (LBA)
PIO Mode 3 and Mode 4
Ultra Advanced Technology Attachment (ATA)/100 (backward-
compatible with ATA/66 and ATA/33)
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
system. To install a SCSI device, you must have a SCSI controller card
installed in your system.
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
Boot SCSI hard drive: SCSI ID 0
SCSI CD drive: SCSI ID 5
SCSI tape or digital audio tape (DAT) drive: SCSI ID 6
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.
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.
If you are installing an external SCSI device, connect one end of the
external SCSI cable to the bus connector on the back of the device.
Attach the other end of the external SCSI cable to the connector on
the controller 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 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 low-voltage differential (LVD) drives
(typically hard drives) both use a 68-pin cable. One end of the cable
attaches to the SCSI controller card. 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
systems.
NOTE: 3.3-volt-only AGP cards are not supported. The AGP connector on the
system board is keyed so that these cards will not fit into your computer.
NOTE: To meet PC99 Workstation requirements, your Dell computer uses
only PCI expansion slots. Industry-Standard Architecture (ISA) expansion
cards are not supported. This is an industry standard for ease-of-use.
NOTICE: Before disconnecting a peripheral from the system or removing a
component from the system board, verify that the standby power indicator on
the system board has turned off. To locate this indicator, see "System Board
Components."
Turn off the computer and peripherals, disconnect them from their
electrical outlets, wait at least 5 seconds, and then remove the
computer cover.
Prepare the expansion card for installation.
See the documentation that came with the expansion card for information on configuring the card, making internal connections, or otherwise customizing it for your system.
Remove the screw that secures the expansion-slot filler bracket to the
chassis, and remove the bracket from the chassis (see the following
figure).
Save the screw to use when installing the expansion card later in this procedure.
Removing the Filler Bracket
CAUTION: Some network interface controllers (NICs)
automatically start up the system when they are connected to a
network. To guard against electrical shock, be sure to unplug your
computer from its electrical outlet before installing any expansion
cards. Verify that the standby power indicator on the system
board is off. To locate this indicator, see "System Board
Components."
Insert the expansion card into the expansion-card connector.
If the expansion card is full-length, insert the end of the card into the expansion-card guide bracket as you lower the card toward its connector on the system board. Insert the card firmly into the expansion-card connector on the system board (see the following figure).
NOTE: The procedure for installing an expansion card in the desktop
chassis is the same as that for the mini tower.

The 3.0-V CR2032 coin-cell battery installed on the system board provides
power to retain the configuration, date, and time information when the
system is turned off. The system battery is designed to provide years of
service without being replaced. However, you may need to replace the
battery if configuration or clock-related inconsistencies occur or if one of
the following messages is displayed during the boot routine:
Time-of-day not set - please run SETUP program
or
Invalid configuration information -
please run SETUP program
or
Strike the F1 key to continue,
F2 to run the setup utility
CAUTION: There is a danger of the new battery exploding if it is
installed incorrectly. Replace the battery only with the same or
equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer's instructions.
If you have not already done so, make a copy of your system
configuration information in system setup.
If the settings are lost while you are replacing the battery, you can refer to your copy of the system configuration information to restore the correct settings.
Turn off the computer and peripherals, disconnect them from their
electrical outlets, wait at least 5 seconds, and then remove the
computer cover.
NOTICE: If you use a blunt, nonconductive object to pry the battery out of its
socket, be careful not to touch the system board with the object. Be sure that
the object is inserted between the battery and the socket before you attempt to
pry out the battery. Otherwise, you may damage the system board.
Pry the battery out of its socket with your fingers or with a blunt, nonconductive object, such as a plastic screwdriver.
Install the new battery.
Orient the battery with the side labeled "+" facing up (see the following figure). Then insert the battery into the socket, and snap it into place.
