3. To enable bootable media in USB drives or in drives inserted into an optional docking device (select models only), use a pointing device or the arrow keys to select System Configuration > Device Configurations. Confirm USB legacy support is selected. NOTE: The USB Port option must be enabled in order to use USB legacy support. It is enabled at the factory. If the port becomes disabled, reenable it by selecting System Configuration > Port Options, and then selecting USB Port. - or - To enable a NIC device, select System Configuration > Boot Options, and then select PXE Internal NIC boot. 4. To save your changes and exit Computer Setup, click the Save icon in the lower-left corner of the screen, and then follow the on-screen instructions. - or - Use the arrow keys to select File > Save Changes and Exit, and then press enter. Your changes go into effect when the computer restarts. NOTE: To connect a NIC to a Preboot eXecution Environment (PXE) or Remote Program Load (RPL) server without using MultiBoot, press esc while the "Press the ESC key for Startup Menu" message is displayed at the bottom of the screen, and then quickly press f12. Considering boot order changes Before changing the boot order, note the following considerations: ● When the computer restarts after the boot order has been changed, the computer attempts to start using the new boot order. ● If there is more than one type of boot device, the computer attempts to boot using the first of each type of boot device (except for optical devices). For example, if the computer is connected to an optional docking device (select models only) that contains a hard drive, this hard drive will be shown in the boot order as a USB hard drive. If the system attempts to boot from this USB hard drive and fails, it will not attempt to boot to the hard drive in the hard drive bay. Instead, it will try to boot to the next type of device in the boot order. However, if there are 2 optical devices, and the first optical device does not boot (either because it does not contain media or the media is not a boot disc), the system will try to boot to the second optical device. ● Changing the boot order also changes the logical drive designations. For example, if you start up from a CD-ROM drive with a disc formatted as drive C, that CD-ROM drive becomes drive C and the hard drive in the hard drive bay becomes drive D. ● The computer will boot from a NIC device only if the device has been enabled in the Built-In Device Options menu of Computer Setup and if booting from the device has been enabled in the Boot Options menu of Computer Setup. Booting from a NIC does not affect logical drive designations because no drive letter is associated with the NIC. ● Drives in an optional docking device (select models only) are treated like external USB devices in the boot order. 70 Chapter 9 MultiBoot

Considering boot order changes
Before changing the boot order, note the following considerations:
●
When the computer restarts after the boot order has been changed, the computer attempts to start
using the new boot order.
●
If there is more than one type of boot device, the computer attempts to boot using the first of each
type of boot device (except for optical devices). For example, if the computer is connected to an
optional docking device (select models only) that contains a hard drive, this hard drive will be shown
in the boot order as a USB hard drive. If the system attempts to boot from this USB hard drive and
fails, it will not attempt to boot to the hard drive in the hard drive bay. Instead, it will try to boot to
the next type of device in the boot order. However, if there are 2 optical devices, and the first optical
device does not boot (either because it does not contain media or the media is not a boot disc),
the system will try to boot to the second optical device.
●
Changing the boot order also changes the logical drive designations. For example, if you start up
from a CD-ROM drive with a disc formatted as drive C, that CD-ROM drive becomes drive C and
the hard drive in the hard drive bay becomes drive D.
●
The computer will boot from a NIC device only if the device has been enabled in the Built-In Device
Options menu of Computer Setup and if booting from the device has been enabled in the Boot
Options menu of Computer Setup. Booting from a NIC does not affect logical drive designations
because no drive letter is associated with the NIC.
●
Drives in an optional docking device (select models only) are treated like external USB devices in
the boot order.
