Solaris Express Installation Guide: Custom JumpStart and Advanced Installations

x86: Command Reference for Booting the System

The following table describes the command-line options for the GRUB menu boot command. The options listed are appropriate for a JumpStart installation.

The syntax of the boot command is the following.

kernel$ /I86PC.Solaris_11-image_directory/platform/i86pc/kernel/$ISADIR/unix/ \
- install [url|ask] \
options -B install_media=media_type

Note –

Starting with the 5/07 Developer release, GRUB has enhanced support for directly booting the unix kernel. For details about these enhancements, see GRUB Menu Commands for Installation in Solaris Express Installation Guide: Network-Based Installations.

Table 6–4 GRUB Menu Boot Command Reference



kernel$ and module$

Starting with the Solaris Express Developer Edition 5/07 release, enables GRUB to determine 32-bit or 64-bit hardware capacity. Results are displayed by using the $ISADIR keyword.

Note –

These new keywords are used in normal installations. However, the miniroot is 32-bit only. Therefore, failsafe installations do not display these keywords.


Resolves to amd64 for 64-bit hardware and resolves to null for 32-bit hardware.

- install

Performs a custom JumpStart installation. 

In the following example, the system boots from DVD media and the following options were used: 

  • - install performs a custom JumpStart

  • file://jumpstart/config.tar finds the JumpStart profile on the local disk

kernel$ /I86pc.Solaris_11.8/platform/i86pc/kernel/unix - install file://jumpstart/config.tar \
 -B install_media=dvdrom module /I86Solaris_11.8/

[url| ask]

Specifies the location of the custom JumpStart files or prompts you for the location.  

  • url – Specifies the path to the files. You can specify a URL for files that are located on an HTTP or HTTPS server:

    The syntax for an HTTP server is the following:

    • If you placed a sysidcfg file in the compressed configuration file, you must specify the IP address of the server that contains the file, as in the following example:

      kernel$ /I86pc.Solaris_11.8/platform/i86pc/kernel/unix install \ \
       -B install_media= \
      module /I86PC.Solaris_11.8/
    • If you saved the compressed configuration file on an HTTP server that is behind a firewall, you must use a proxy specifier during boot. You do not need to specify an IP address for the server that contains the file. You must specify an IP address for the proxy server, as in the following example:

      kernel$ /I86pc.Solaris_11.8/platform/i86pc/kernel/unix install \ \
       -B install_media= \
      module /I86PC.Solaris_11.8/
  • ask – Specifies that the installation program prompt you to type the location of the compressed configuration file. You are prompted after the system boots and connects to the network. If you use this option, you are not able to do a completely hands off JumpStart installation.

    If you bypass the prompt by pressing Return, the Solaris installation program interactively configures the network parameters. The installation program then prompts you for the location of the compressed configuration file.

    The following example performs a custom JumpStart and boots from DVD media. You are prompted to type the location of the configuration file after the system connects to the network.

    kernal$ /boot/I86PC.Solaris_11.8/platform/i86pc/kernel/unix/ install ask -B \
    install_media= module \


  • dhcp – Specifies to use a DHCP server to obtain network installation information that is needed to boot the system. This option is not needed for a JumpStart installation. If you do not specify to use a DHCP server by typing dhcp, the system uses the /etc/bootparams file or the naming service bootparams database. For example, you would not specify dhcp if you wanted keep a static IP address. For example:

    kernel$ /I86pc.Solaris_11.8/platform/i86pc/kernel/unix install \
    dhcp -B install_media= \
    boot module /I86PC.Solaris_11.8/
  • The options nowin and text do not apply to a JumpStart installation. These options are useful with an interactive installation. For more information, see To Install or Upgrade With the Solaris Installation Program With GRUB in Solaris Express Installation Guide: Basic Installations.
