128 or 256 KB of external static random-access memory (SRAM) level 2 (L2)
cache, depending on your microprocessor.
• A minimum of 32 MB of memory, which you can increase up to 512 MB by
installing a combination of 32-, 64-, 128-, 192-, or 256-MB 3.3-volt (V) small-
outline, dual in-line memory modules (SODIMMs) in the two memory module
sockets on the system board.
• Power conservation modes, standby (sleep) mode and save-to-disk suspend
(hibernate) mode, which help you conserve battery power. The standby mode
enables you to conserve battery power without shutting down application
programs or files. If the batteries run out of power, save-to-disk suspend mode
prevents data loss by copying all system data to the hard-disk drive and turning
off the computer.
• A special media bay and a variety of combination modules that extend the
functionality of your computer. You can select a CD-ROM drive/diskette drive
module, a DVD-ROM drive/diskette drive module, a DVD-ROM drive/LS-120
drive, an optional second battery, or an optional third hard-disk drive.
NOTE: The optional media bay hard-disk drive is not bootable.
• A MegaBay, in which you can use a battery, a second hard-disk drive, or a Zip
drive.
NOTE: The optional MegaBay hard-disk drive and the Zip drive are not bootable.
• Sixteen-bit stereo audio with Dolby AC3 decode, hardware wavetable, 3D
surround sound, and integrated speakers and microphone. Connectors for
attaching external speakers, headphones, or a microphone to your computer
are also included.
NOTE: The Dolby AC3 decode can only be used with the optional port replicator.
• Support for up to two 3.3-V or 5-V PC Cards. The computer supports up to two
Type I or Type II cards (in any combination) or one Type III card. Dell-installed
device drivers on the hard-disk drive support the operation of many standard
PC Cards.
• A basic input/output system (BIOS) that resides in flash memory and can
be upgraded by diskette. You can obtain a BIOS upgrade, if required, on
diskette from Dell or you can download the upgrade from Dell’s Web site at
http://support.dell.com. See Chapter 5, “Getting Help,” for more information
on Dell’s online services.
• High-performance parallel and serial ports, and a multipurpose Personal System/2
(PS/2) connector for attaching external devices.
• A video connector allows you to attach an external monitor to your computer.
• A PS/2-compatible touch pad that gives your computer full mouse functionality.
• An infrared port for use with compatible external devices. The infrared port
permits file transfers without using cable connections. Fast infrared technology is
also available.
