System Setup

This computer offers you the following options:

•Access System Setup by pressing <F2>

•Bring up a one-time boot menu by pressing <F12>

Press <F2> to enter System Setup and make changes to the user-definable settings. If you have trouble entering System Setup using this key, press <F2> when the keyboard LEDs first flash.

Boot Menu

This feature gives users a quick and convenient mechanism to bypass the System Setup-defined boot device order and boot directly to a specific device (for example: floppy, CD-ROM, or hard drive).

Keystroke	Function

<Ctrl><Alt><F8>	one-time boot and diagnostics utility menu
<F12>	one-time boot and diagnostics utility menu

Boot Menu Enhancements

The boot menu enhancements are as follows:

•Easier access — Although the <Ctrl><Alt><F8> keystroke still exists and can be used to call up the menu, simply press <F12> during system boot to access the menu.

•User prompting — Not only is the menu easy to access, when you are prompted to use the keystroke on the BIOS splash screen (see image below). The keystroke is not "hidden".

•Diagnostics options — The boot menu includes two diagnostic options, IDE Drive Diagnostics (90/90 Hard Drive Diagnostics) and Boot to the Utility Partition. The benefit here is that you do not have to remember the <Ctrl><Alt><D> and <Ctrl><Alt><F10> keystrokes (although they still work).

NOTE: The BIOS features an option to disable either or both of the keystroke prompts under the System Security / Post Hotkeys submenu.

When you enter the <F12> or <Ctrl><Alt><F8> keystroke correctly, the computer beeps. The key sequence invokes the Boot Device Menu.
