If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop. Then shut down your computer and try again.

System Setup Screens

The system setup screen displays current or changeable configuration information for your computer. Information on the screen is divided into three areas: the options list, active options field, and key functions.

Options List — This field appears on the left side of the system setup window. The field is a scrollable list containing features that define the configuration of your computer, including installed hardware, power conservation, and security features.

Scroll up and down the list by using the up- and down-arrow keys. As an option is highlighted, the Option Field displays more information about that option and the option's current and available settings.

Press <Enter> to expand or contract each of the main option fields.

Option Field — This field contains information about each option. In this field you can view your current settings and make changes to your settings.

Use the right- and left-arrow keys to highlight an option. Press <Enter> to make that selection active.

Key Functions — This field appears below the Option Field and lists keys and their functions within the active system setup field.

 

System Setup Options

NOTE: Depending on your computer and installed devices, the items listed in this section may not appear, or may not appear exactly as listed.

System

CPU Info

Memory Info

Indicates amount of installed memory, memory speed, channel mode (dual or single), and type of memory installed.

Date/Time

Displays current date and time settings.

Boot Sequence

The computer attempts to boot from the sequence of devices specified in this list.

NOTE: If you insert a boot device and restart the computer, this option appears in the system setup menu. To boot from a USB memory device, select the USB device and move it so it becomes the first device in the list.

Drives

Diskette Drive

Drives 0 through 3

Identifies the drives attached to the PRI IDE connectors on the system board, and lists the capacity for hard drives.

NIC Controller

You can set the NIC to On (default), Off, or On w/ PXE. When the On w/ PXE setting is active (available only for the future boot process), the computer prompts the user to press <Ctrl><Alt><b>. Pressing this key combination causes a menu to display that allows you to select a method for booting from a network server. If a boot routine is not available from the network server, the computer attempts to boot from the next device in the boot sequence list.

Audio Controller

Enables or disables the onboard audio controller.

USB

Set to On (default) so that USB devices will be detected and supported in the operating system.

The No Boot option restricts external access to drive data. Use this option to prohibit users from booting the computer using an external USB device.

Mouse Port

Enables or disables the onboard PS/2-compatible mouse controller.

LPT Port Mode

Identifies and defines the parallel port settings. You can set the parallel port to Off, AT, PS/2, EPP, or ECP.

If your computer's processor supports Hyper-Threading, these options appear in the Options List.

Performance
  • Bypass — Your computer does not test or change the current acoustics mode setting.
  • Quiet (default) — The hard drive operates at its most quiet setting.
  • Suggested — The hard drive operates at the level suggested by the drive manufacturer.
  • Performance — The hard drive operates at its maximum speed.

NOTE: Switching to performance mode may cause the drive to be noisier, but its performance may not be affected.

NOTE: Changing the acoustics setting does not alter your hard drive image.

Security

NOTE: Normally, the computer can be powered up remotely from suspend mode, hibernate mode, or when powered off. When Low Power Mode (in the Power Management menu) is enabled, the computer can only be powered up remotely from Suspend.

Suspend Mode

The options are S1, a suspend state where the computer is running in a low-power mode, and S3, a standby state where the power is reduced or turned off for most components, however, system memory remains active.
