NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris  invokes  the  Solaris  Install  program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

           Minimum physical memory for all installation types

       128 MB

           Minimum physical memory required for windowing system

       384 MB

           Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

           Minimum physical memory for all installation types

       256 MB

           Minimum physical memory required for windowing system

       512 MB

           Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris  exists  only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
