attached devices such as hard disk, video adapter, keyboard, mouse, and
printer.

Boot menu
The Inspiron 13-5378 includes a one-time boot menu. By using this feature,
you can change the sequence of devices that your computer attempts to
boot from, for example, floppy, CD-ROM, or hard drive.
Boot menu enhancements
The boot menu enhancements are as follows:
•
Easier Access – Press F12 to access the boot selection menu.
•
User Prompting – The user is prompted to use the keystroke on the BIOS
screen.
•
Diagnostics Options – The boot menu includes the ePSA diagnostic

Timing key sequences
The keyboard is not the first device initialized by Setup. As a result, if you press
a keystroke too early, the keyboard is locked out. In such case, a keyboard
error message is displayed on the screen, and you cannot restart your
computer with the Ctrl+Alt+Del key combination.
To prevent the keyboard from locking, wait until the keyboard is initialized
completely. The keyboard is initialized if one of the following occurs:
•
The keyboard lights flash.
•
The F2=Setup prompt appears at the top right corner of the screen during
boot.
