Selecting a Boot Device

The boot device is specified by the setting of an OpenBoot configuration variable
called boot-device. The default setting of this variable is disk net. Because of
this setting, the firmware first attempts to boot from the system hard drive, and if
that fails, from the on-board NET0 Gigabit Ethernet interface.
This procedure assumes that you are familiar with the OpenBoot firmware and that
you know how to enter the OpenBoot environment. For more information, see the
Sun Fire T200 Server Administration Guide.
Note – The serial management port on the ALOM card is preconfigured as the
default system console port. For more information, see the Sun Fire T2000 Server
Overview.
If you want to boot from a network, you must connect the network interface to the
network.
