Specifically, you must set up a system console and power on the system. See:

■“How to Set Up an Alphanumeric Terminal as the System Console” on page 133

■“How to Configure a Local Graphics Terminal as the System Console” on page 135

■“How to Power On the System” on page 122

If you want to boot from a network, you must also connect the network interface to the network and configure the network interfaces. See:

■“How to Attach a Twisted-Pair Ethernet Cable” on page 127

■“How to Configure the Primary Network Interface” on page 144

■“How to Configure Additional Network Interfaces” on page 146

What to Do

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 “About the ok Prompt” on page 49.

●At the ok prompt, type:

ok setenv boot-device device-specifier

where the device-specifieris one of the following:

■cdrom – Specifies the DVD-ROM drive

■disk – Specifies the system boot disk

■disk0 – Specifies internal disk 0

■disk1 – Specifies internal disk 1

■net, net0, net1– Specifies the network interfaces

■full path name – Specifies the device or network interface by its full path name

Note – You can also specify the name of the program to be booted as well as the way the boot program operates. For more information, see the OpenBoot 4.x Command Reference Manual, included with the Solaris Software Supplement CD that ships with Solaris software.
