Boot Menu; Boot Menu Enhancements; Timing Key Sequences - Dell Inspiron 22 3263 Service Manual

Boot menu

This computer includes a one-time boot menu. This feature allows you to 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 options.

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.
