Available Upgrades

The upgrades Dell offers undergo rigorous testing to ensure proper operation with

your computer. You should review “PCI Expansion Card Upgrades” in Chapter 2 to be

sure you have the necessary slots or resources available before purchasing such an

upgrade.

Dell offers a variety of expansion cards to increase system functionality:

•Fax/modem card

•10/100 –megabit-per-second (Mbps) network card

You can expand your system's memory up to 512 MB by installing additional 168-pin,

100-megahertz (MHz) non-error checking and correction (non-ECC) SDRAM DIMMs in

the DIMM sockets on the system board. Purchasing memory upgrades from Dell

Spare Parts ensures system compatibility; these upgrades are also covered under

your system warranty. See “Adding Memory” in Chapter 2 before purchasing a mem-

ory upgrade.

To order any of these upgrades, call Dell.

Padlock Ring

On the back of the computer is a padlock ring (see Figure 1-1) for attaching commer-

cially available theft-deterrent devices.
