10 About Your System
• Updates are sometimes included with the system to describe changes to 
the system, software, and/or documentation.
  NOTE: Always check for updates on support.dell.com and read the updates 
first because they often supersede information in other documents.
• Release notes or readme files may be included to provide last-minute 
updates to the system or documentation or advanced technical reference 
material intended for experienced users or technicians.
Accessing System Features During Startup
Table 1-1 describes keystrokes that may be entered during startup to access 
system features. If your operating system begins to load before you enter the 
keystroke, allow the system to finish booting, and then restart your system 
and try again.
