64-bit: How Do I Install the 64-bit Solaris Operating Environment?

Software selection choices include a 64-bit support option when installing the Solaris 7 release for all system types:

• On UltraSPARC systems, 64-bit support is selected by default. You can override this default by deselecting the 64-bit support.

• For all other systems, 32-bit support is selected by default. You can override this default by selecting 64-bit support, available in the Developer and Entire Distribution software clusters, which will provide the 64-bit Solaris libraries for developers who wish to develop 64-bit applications on 32-bit systems.

Look for the 64-bit support option during the various Solaris 7 installation scenarios:

• For an initial installation using the Solaris interactive installation program, the 64-bit support option is displayed on the Software Selection screen, which prompts for the type of system software to be installed: End User, Developer, or Entire Distribution.

• For an upgrade using the Solaris interactive installation program, the 64-bit support option is displayed on the Customize Software screen that appears prior to the start of the software upgrade.

• For an initial installation using Solaris Web Start, the 64-bit support option is displayed on the Configure Solaris screen, which is found after pressing the Custom Install button.

• For an initial installation or upgrade using the custom JumpStart^TM technology, 32-bit or 64-bit support can be selected using the profile. Add one of the following keyword value pairs to the profile:

  isa_bits 32

  isa_bits 64
