front-panel latches snap into the tabs on the front panel.
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at support.dell.com.
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"). "System Board Components" in "About Your
Computer" shows the location of the four RIMM sockets on the system board. Sockets
that do not contain a RIMM must contain Rambus continuity RIMMs (CRIMMs).
NOTE: 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 Showing Number of Memory
Devices" 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.
NOTE: The system does not support
RIMMs with six memory devices.
NOTE: All four RIMM slots 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 provide 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.
NOTICE: Be sure to install a RIMM
in socket 1 first (closest to the processor) before installing a RIMM in socket 2.
CAUTION: RIMMs can get very
hot during system operation. Be sure that the RIMMs have had sufficient time to cool
before you touch them.
Turn off the computer and peripherals, disconnect them
from their electrical outlets, wait at least 5 seconds, and then remove
the computer cover.
Rotate the power supply away from the system board.
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 Showing Number of Memory Devices" 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.

See the operating system's documentation for instructions.
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 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
The secondary EIDE connector, labeled "IDE SEC," should be cabled to EIDE CD,
DVD, tape, SuperDisk, and Zip drives
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 "System Board Components." Each EIDE interface connector on
the I/O board supports the following:
Two channels, master and slave
Logical block addressing (LBA)
Programmed I/O (PIO) Mode 3 and Mode 4
Ultra Advanced Technology Attachment (ATA)/100, ATA/66, or ATA/33
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.
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. If you have any
SCSI devices on the second EIDE channel, Secondary Drive 0 and/or Secondary
Drive 1 should be set to None.
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.
Ultra2/Wide low-voltage differential (LVD) drives (typically hard drives) use a 68-pin
cable. One end of this cable attaches to the SCSI controller card. The remaining
connectors on the cable attach to the various LVD 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: To meet PC99 system
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 device from the computer, wait 10 to 20 seconds after disconnecting the
computer from its electrical outlet. Before removing a component from the system board,
