How to Select the Boot Device

Before You Begin
Before you can select a boot device, you must complete the installation procedure;
see:
"How to Install the Enterprise 250 Server" on page 13
Specifically, you must perform the following tasks:
Set up a system console; see "About Setting Up a Console" on page 19
Power on the system; see "How to Power On the System" on page 27
If you want to boot across a network interface, then you must also perform the
following tasks:
Configure the Ethernet port; see "How to Configure the Standard Ethernet
Interface" on page 173
Attach the Ethernet port to a network; see "How to Attach a Twisted-Pair
Ethernet (TPE) Cable" on page 178 or "How to Attach an MII Ethernet
Transceiver" on page 180
The device that is used to boot the system is determined by the setting of an
OpenBoot firmware configuration parameter called boot-device. The default
setting of this parameter is disk net. Because of this setting, the firmware first
attempts to boot from the system hard drive, and if that fails, then from the main
logic board 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 about the
OpenBoot firmware, see OpenBoot 3.x Command Reference Manual in the Solaris System
Administrator AnswerBook for your specific Solaris release.
