Booting Up
User Guide—Sun Cobalt LX50 Server 4-5
Service Partition <F4>
Press F4 to boot to the service partition. This partition allows you to set configuration parameters and run diagnostics.
See “Using the Service Partition Menu” on page 4-9 for more details.
When you are finished using the service partition, you must depress the Ctrl-Alt-Delete keys simultaneously to
reboot.
Network <F12>
Press F12 to boot from the network. The server software then looks for a valid boot file name on the network. If it
finds such a file name, it boots from the network. If it cannot find a valid file name, it gives up and continues to boot
from the hard disk. Figure 40 is an example of how the screen appears when booting from the network fails.

PXE (Pre-boot Execution Environment) is a method by which the server can booted from a remote server. This allows
the system to boot without any knowledge of the Operating System on the server. The PXE environment uses DHCP
to obtain network addresses. PXE is primarily used for loading operating systems, configuring the system, or burn-in
type testing. PXE booting will only work if a properly configured PXE server is available.
Choose Boot Device <ESC>
Press the Esc key to go to the boot device selection menu. This menu, shown in Figure 41, allows you to select the
device from which the system will boot. To select a boot device, scroll to the desired device and press Enter;
otherwise, press Esc to exit without changing the boot device.

Note : When you select a boot device with the menu shown in Figure 41, it only affects the
current boot. Subsequent boots revert to the device stored in the BIOS default settings.
