Dell PowerEdge 500SC - Manual (Page 21)

Boot Sequence Screen
The Boot Sequence screen options determine the order in which the system looks for the files that it needs to load during system startup. Available options
include the diskette drive, CD drive, and hard drive. You can enable or disable a device by selecting it and pressing the spacebar. To change the order in which
devices are searched, use the <+> and <-> keys.
Hard-Disk Drive Sequence Screen
The Boot Sequence screen options determine the order in which the system searches hard drives for the files that it needs to load during system startup. The
choices depend on the particular hard drives installed in your system. You can enable or disable a device by selecting it and pressing the spacebar. To change
the order in which devices are searched, use the <+> and <-> keys.
Integrated Devices Screen
The following devices on the system board are configured through this screen:
l Network Interface Controller — determines whether the system's integrated NIC is enabled. Changes take effect after reboot.
l NIC MAC Address — displays the address of the MAC address used by the integrated NIC. This field has no user-selectable settings.
l Mouse Controller — enables or disables the system's mouse controller; disabling the mouse controller allows an expansion card to use IRQ12.
l Serial Port 1 — configure the system's integrated serial port; the options can be set to Auto (the default) to automatically configure a port, to a
particular designation, or to Off to disable the port.
If you set a serial port to Auto and add an expansion card containing a port configured to the same designation, the system automatically remaps the
integrated port to the next available port designation that shares the same IRQ setting.
l Parallel Port — configures the system's integrated parallel port.
l Parallel Port Mode — controls whether the system's integrated parallel port acts as an AT-compatible (unidirectional) or PS/2-compatible (bidirectional)
port; to determine the correct mode to use, see the documentation that came with the peripheral device connected to the serial port.
l USB Controller — enables or disables the system's USB ports; disabling the USB ports makes system resources available for other devices.
l IDE Interface — enables or disables the system's IDE interface.
l Diskette Controller — enables or disables the system's diskette drive controller; with Auto (default) selected, the system turns off the controller when
necessary to accommodate a controller card installed in an expansion slot.
System Security Screen
You can set the following security features through the System Security screen:
l Password Status — when Setup Password is set to Enabled, allows you to prevent the system password from being changed or disabled at system
start-up.
To lock the system password, you must first assign a setup password in the Setup Password option and then change the Password Status option to
Locked. In this state, the system password cannot be changed through the System Password option and cannot be disabled at system start-up by
pressing .
To unlock the system password, you must enter the setup password in the Setup Password option and then change the Password Status option to
Unlocked. In this state, the system password can be disabled at system start-up by pressing and then changed through the System
Password option.
l System Password — displays the current status of your system's password security feature and allows you to assign and verify a new password.
l Setup Password — lets you restrict access to your system's System Setup program in the same way that you restrict access to your system with the
system password feature.
l Power Button Override — when Power Button Override is set to Disabled, you can use the power button to turn off, or shut down the system if
running Microsoft® Windows® 2000 or another operating system compliant with the APCI specification. When Power Button Override is set to
Enabled, you cannot use the power button to turn off the system or perform other system events.
Exit Screen
After you press to exit the System Setup program, the Exit screen displays the following choices:
l Save Changes and Exit
l Discard Changes and Exit
l Return to Setup
