CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the
metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity,
which could harm internal components.
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 or thumb-screws that you must disengage before disconnecting the cable. When disconnecting
cables, keep them evenly aligned to avoid bending any connector pins. When connecting cables, ensure that the ports and
connectors are correctly oriented and aligned.

Use the BIOS Setup program for the following purposes:
• Get information about the hardware installed in your computer, such as the amount of RAM and the size of the hard drive.
• Change the system conguration information.
• Set or change a user-selectable option, such as the user password, type of hard drive installed, and enabling or disabling base devices.

NOTE
: The F2 prompt indicates that the keyboard is initialized. This prompt can appear very quickly, so you must watch for
it, and then press F2. If you press F2 before the F2 prompt, this keystroke is lost. If you wait too long and the operating
