Using the Setup Password Feature
l
OS Install Mode — determines the maximum amount of memory available to the operating system; On sets the maximum memory available to the operating
system to 256 MB; Off (default) makes all of the system memory available to the operating system.
l
Keyboard Numlock — determines whether your system boots with the Num Lock mode activated on 101- or 102-key keyboards (it does not apply to 84-
key keyboards).
l
Report Keyboard Error — enables or disables reporting of keyboard errors during the POST.
This option is useful when applied to self-starting servers or host systems that have no permanently attached keyboard. In these situations, selecting Do Not
Report suppresses all error messages relating to the keyboard or to the keyboard controller during POST. This setting does not affect the operation of the
keyboard itself if a keyboard is attached to the system.
l
Asset Tag — displays the customer-programmable asset tag number for the system if an asset tag number has been assigned; to enter an asset tag number of
up to ten characters into NVRAM, follow the procedure in "
Asset Tag Utility
" in "

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-ROM drive, and hard-disk 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-disk drives for the files that it needs to load during system startup. The
choices depend on the particular hard-disk 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
Embedded SCSI Controller — Channel A and Channel B turn the respective SCSI controller on or off. Selecting On (the default setting) enables the
integrated PCI SCSI controller and scans the associated ROM; for the system to boot from a drive attached to the integrated SCSI controller, the drive must be
enabled. Selecting Off causes the BIOS to mask the presence of a device.
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, Serial Port 2 — configure the system's integrated serial ports; 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 CD-ROM Interface — enables or disables the system's IDE CD-ROM 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.
l
Speaker — determines whether the integrated speaker is On (the default) or Off; a change to this option takes effect immediately (rebooting the system is not
required).
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
