During the boot process, the boot subsystem menus allow you to customize boot choices. If the system receives no response during the timeout periods, it continues to boot automatically using the default selections. You can stop the boot process when each boot subsystem menu is displayed. Or, you can let the boot process continue automatically.
At three points during the Solaris boot process, you can make the following choices about a booting system:
Primary Boot Subsystem (Partition Boot Menu) – This first menu appears if multiple operating systems exist on the disk. The menu enables you to boot any of the operating systems installed. By default, the operating system that is designed as active is booted.
Note that if you choose to boot a system other than the Solaris Operating System, you cannot reach the next two menus.
Interrupt the Autoboot Process – If the autoboot process is interrupted, you can access the Device Configuration Assistant menu.
The Solaris Device Configuration Assistant enables you to boot the Solaris system from a different boot device, configure new or misconfigured hardware, or perform other device-related or boot-related tasks.
Current Boot Parameters menu – Two forms of this menu exist, one menu for a normal Solaris boot and one menu for a Solaris installation boot:
The normal Current Boot Parameters menu enables you to boot the Solaris system with options, or enter the boot interpreter.
The install Current Boot Parameters menu enables you to select the type of installation to be performed or to customize the boot process.
The following table summarizes the purpose of the primary x86 based system boot interfaces. See the sections that follow for a detailed description and example of each boot interface.
Table 13.2. Boot Subsystems
|
Boot Subsystem |
Purpose |
|---|---|
|
Primary Boot Subsystem (Partition Boot menu) |
This menu appears if the disk you are booting from contains multiple operating systems, including the Solaris Operating System (Solaris OS). |
|
Secondary Boot Subsystem |
This menu appears each time you boot the Solaris release. The Solaris release is booted automatically unless you choose to run the Solaris Device Configuration Assistant by interrupting the autoboot process. |
|
Solaris Device Configuration Assistant/Boot Diskette |
There are two ways to access the Device Configuration Assistant menus:
|
|
Current Boot Parameters menu |
This menu appears when you boot the Solaris release from the disk, CD-ROM, or the network. The menu presents a list of boot options. |
If you need to create the Solaris Device Configuration Assistant boot diskette, go to http://www.sun.com/bigadmin/hcl/drivers/dca_diskettes/.
In this release, if you are booting an x86 based system with the Solaris Software 1 CD, DVD, or performing a PXE network boot, the system will boot automatically. To use the Device Configuration Assistant, you must interrupt the boot process by pressing Esc when prompted by the system.
During the device identification phase, the Device Configuration Assistant does the following:
Scans for devices that are installed on the system
Displays the identified devices
Enables you to perform optional tasks such as selecting a keyboard type or editing devices and their resources
During the boot phase, the Device Configuration Assistant does the following:
Displays a list of devices from which to boot. The device marked with an asterisk (*) is the default boot device.
Enables you to perform optional tasks, such as editing autoboot settings and property settings, and choosing the network configuration strategy.
The following section provides examples of menus that appear during the device identification phase. The device output varies based on your system configuration.
Several screens are displayed as the Device Configuration Assistant attempts to identify devices on the system. This section provides examples of the following boot subsystem screens:
Device Configuration Assistant screen
Bus Enumeration screen
Scanning Devices screen
Identified Devices screen
In the current Solaris release, the Device Configuration Assistant Screen has been replaced with the GRUB menu on x86 based systems. For more information, see Chapter 11, GRUB Based Booting (Tasks).
In the Solaris 10 initial release, the autoboot process bypasses the Device Configuration Assistant menus, unless you press Esc when prompted by the system during the boot phase. If you choose to use the Device Configuration Assistant, the following screen is displayed.
Solaris Device Configuration Assistant
The Solaris(TM)Device Configuration Assistant
scans to identify system hardware, lists identified devices, and can
boot the Solaris software from a specified device. This program must be
used to install the Solaris operating environment, add a driver,
or change the hardware on the system.
> To perform a full scan to identify all system hardware, choose Continue.
> To diagnose possible full scan failures, choose Specific Scan.
> To add new or updated device drivers, choose Add Driver.
About navigation...
- The mouse cannot be used.
- If the keyboard does not have function keys or they do not respond,
press ESC. The legend at the bottom of the screen will change to
show the ESC keys to use for navigation.
- The F2 key performs the default action.

The Identified Devices screen displays which devices have been identified on the system. From here, you can continue to the Boot Solaris menu. Or, you can perform the following optional device tasks:
Setting a keyboard configuration
Viewing and editing devices
Setting up a serial console
Saving and deleting configurations
Identified Devices The following devices have been identified on this system. To identify devices not on this list or to modify device characteristics, such as keyboard configuration, choose Device Tasks. Platform types may be included in this list.

During this phase, you can determine the way in which the system is booted. The following menus are displayed during the boot phase:
Boot Solaris menu
Current Boot Parameters menu
The Boot Solaris menu allows you to select the device from which to boot the Solaris release. You can also perform optional tasks, such as viewing and editing autoboot and property settings. Once you select a boot device and you choose Continue, the Solaris kernel begins to boot.
Boot Solaris
Select one of the identified devices to boot the Solaris kernel and
choose Continue.
To perform optional features, such as modifying the autoboot and property
settings, choose Boot Tasks.
An asterisk (*) indicates the current default boot device.
> To make a selection use the arrow keys, and press Enter to mark it [X].
