To install or upgrade to the Solaris operating environment, the suggested memory size is 128 Mbytes or greater. You must have a minimum of 96 Mbytes to use DVD media to install and 64 Mbytes to use CD media to install.
Some optional installation features are enabled only when sufficient memory is present. For example, if you install from a DVD with 96 Mbtyes of memory, you install through the Solaris Web Start command line interface, not through the Solaris Web Start graphical user interface.
