WARNING: Before working inside your computer, read the safety information
that shipped with your computer. For additional safety best practices information,
see the Regulatory Compliance Homepage at dell.com/regulatory_compliance.
WARNING: Disconnect all power sources before opening the enclosure to
replace, remove, or install accessories. After the installation is completed, the
enclosure must be replaced and all fasteners installed before connecting to the
power source.
CAUTION: Only a certified service technician is authorized to remove the
computer cover and access any of the components inside the computer. See the
safety instructions for complete information about safety precautions, working
inside your computer, and protecting against electrostatic discharge.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist
grounding strap or by periodically touching an unpainted metal surface (such as a
connector on your computer).
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab,
not on the cable itself. Some cables have connectors with locking tabs; if you are
disconnecting this type of cable, press in on the locking tabs before you
disconnect the cable. As you pull connectors apart, keep them evenly aligned to
avoid bending any connector pins. Also, before you connect a cable, ensure that
both connectors are correctly oriented and aligned.
CAUTION: To avoid damaging the computer, perform the following steps before
you begin working inside the computer.
1 Ensure that the work surface is flat and clean to prevent the computer
display from being scratched.
2 Turn off your computer and all attached devices. See "Turning Off Your
Computer" on page 11.
CAUTION: To disconnect a network cable, first unplug the cable from your
computer and then unplug the cable from the network device.

Boot Sequence
This feature allows you to change the boot sequence for devices.
Boot Options
•
Diskette Drive — The computer attempts to boot from the floppy disk
drive. If no operating system is on the drive, the computer generates an
