computer to effect the changes.
Manageability
Alert Standard Format
ASF is a DMTF management standard that specifies "pre-operating system" or "operating system-absent" alerting techniques. The standard is designed to
generate an alert on potential security and fault conditions when the operating system is in a sleep mode or the system is turned off. ASF is designed to
supersede previous operating-system-absent alerting technologies.
Your computer supports the following ASF version 1.03 and 2.0 alerts and remote capabilities:
For more information about Dell's ASF implementation, see the ASF User's Guide and the ASF Administrator's Guide, which are available on the Dell Support
website at support.dell.com.

Power Management
Your computer can be set to use less power when you are not working. You control the power usage through the operating system installed on your computer
and certain option settings in system setup. These periods of reduced power are called "sleep modes."
lStandby. In this sleep mode, power is reduced or turned off for most components, including the cooling fans. However, system memory remains active.
lHibernate. This sleep mode reduces power consumption to a minimum by writing all data in system memory to a hard drive and then removing system
power. Waking up from this mode restarts the computer, and the memory contents are restored. Operation then resumes where the computer left off
when it entered the hibernation mode.
lShutdown. This sleep mode removes all power from the computer except a small auxiliary amount. As long as the computer remains connected to an
electrical outlet, it can be automatically or remotely started. For example, the Auto Power On option in system setup allows the computer to
automatically start at a specified time. Also, your network administrator can remotely start your computer using a power management event such as
Remote Wake Up.
The following table lists the sleep modes and the methods you can use to wake the computer from each mode.
Back to Contents Page
NOTE: All components installed in the computer must support the hibernate and/or standby mode feature(s) and have the appropriate drivers loaded to
enter either of these sleep modes. For more information, see the manufacturer's documentation for each component.

DDR2 Memory Overview
Addressing Memory With 4-GB Configurations
Removing Memory
Replacing/Adding Additional Memory
For information on the type of memory supported by your computer, see the "Memory" section of the specifications for your computer:
lMini Tower Computer Specifications
lDesktop Computer Specifications
lSmall Form Factor Computer Specifications
DDR2 Memory Overview
Dual-channel DDR2 memory modules should be installed in pairs of matched memory size. If the DDR2 memory modules are not installed with the same amount
of memory in each channel, the computer will continue to operate, but with a slight reduction in performance. See the label in the upper-right corner of the
module to determine the module's capacity.
The recommended memory configurations are:
lA pair of matched memory modules installed in connectors DIMM1 and DIMM2
or
lA memory module installed in connector DIMM1
Be sure to install a single memory module in DIMM1, the connector closer to the processor, before you install a module in the other connector.
Addressing Memory With 4-GB Configurations
This computer supports a maximum of 4 GB of memory when you use two 2-GB DIMMs. Current operating systems, such as Microsoft®Windows®XP, can only
use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than 4 GB. Certain components within the
computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.
The following components require memory address space:
lSystem ROM
lAPIC(s)
lIntegrated PCI devices, such as network connectors and SCSI controllers
lPCI cards
lGraphics card
lPCI Express cards (if applicable)
At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required.
The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.
lIf the total installed computer memory is less than the usable space, all installed computer memory is available for use only by the operating system.
lIf the total installed computer memory is equal to or greater than the usable address space, a small portion of installed memory is available for use by
the operating system.
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at
support.dell.com.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
NOTICE: Do not install ECC memory modules. Doing so may cause the system not to boot or affect performance.
Removing Memory
1. Follow the procedures in "Before You Begin."
2. Carefully press out the securing clip at each end of the memory module connector.
3. Remove the memory module.
Replacing/Adding Additional Memory
1. Follow the procedures in "Before You Begin."
2. Press out the securing clip at each end of the memory module connector.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that
you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module.
Otherwise, your computer may not start properly. You should install your original memory modules in pairs either in connectors DIMM1 and DIMM2 or
connectors DIMM3 and DIMM4.
NOTICE: Removing memory modules from DIMM2 and DIMM4 on the desktop computer requires you to remove the optical drive (see "Drives"). Failure
to do so may cause damage to the memory module and the DIMM socket.
NOTE: Memory purchased from Dell is covered under your computer warranty.

If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.
5. Replace the computer cover.
6. The computer detects that the new memory does not match the existing 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
7. Press <F2> to enter system setup and check the value for System Memory.
The computer should have changed the value of System Memory to reflect the newly installed memory. Verify the new total. If it is correct, skip to
step9.
8. If the memory total is incorrect, turn off and disconnect your computer and devices from their electrical outlets. Open the computer cover and check the
installed memory modules to ensure that they are seated properly in their sockets. Then repeat steps 5, 6, and 7.
9. When the System Memory total is correct, press <Esc> to exit system setup.

Drives
Drives
Your computer supports:
lTwo serial ATA hard drives
lTwo floppy or optional Zip drives
lTwo CD or DVD drives
General Installation Guidelines
Connect CD/DVD drives to the connector labeled "IDE" on the system board. Serial ATA hard drives should be connected to the connectors labeled "SATA0" or
"SATA2" on the system board.
IDE Drive Addressing
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device 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).
See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board.
Drive Interface Connectors
NOTE: Due to the limited number of drive bays and IDE controllers on this computer, you will not be able to connect all supported devices at once.

IDE Drive Connector
Serial ATA
Connector
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the IDE cable—serial ATA cables do not
use a colored stripe) goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1"
printed directly on the board or card.
Power Cable Connectors
Connecting and Disconnecting Drive Cables
When removing an IDE drive data cable, grasp the colored pull-tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at each end.
Like IDE connectors, the serial ATA interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a
filled-in hole on the other connector.
