Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 16)

Diskette Controller — Enables or disables the system's diskette drive controller. When Auto (default) is selected, the
system turns off the controller when necessary to accommodate a controller card installed in an expansion slot. You
can also set up the drive to be read-only. The read-only setting prevents the drive from being used to write to a disk.
USB Controller — Enables or disables the system's USB ports. Disabling the USB ports makes system resources
available for other devices.
Embedded 10/100/1000 NIC — Enables or disables the system's two integrated NICs. Options are Enabled
without PXE, Enabled with PXE, and Disabled. PXE support allows the system to boot from the network. Changes
take effect after the system reboots.
MAC Address — Displays the MAC address for the 10/100/1000 NIC that is used by the corresponding integrated NIC.
This field has no user-selectable settings.
Mouse Controller — Enables or disables the system's mouse controller. Disabling the mouse controller allows an
expansion card to use IRQ12.
Serial Port (1 and 2) — Configures the system's integrated serial ports. The options can be set to Auto (default) to
automatically configure the port, to a particular designation, or to Off to disable the port.
If you set the serial port to Auto and add an expansion card with 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.
Speaker — Toggles the integrated speaker On (default) or Off. A change to this option takes effect immediately
(rebooting the system is not required).

Password Status option to Unlocked. In this state, the system password can be disabled at system start-up by pressing

Setup Password — Allows you to restrict access to the System Setup program in the same way that you restrict
access to your system with the system password feature.

changing an existing setup password. See " Disabling a Forgotten Password " for instructions on disabling a
