To boot with the suninstall program, you don’t use the Solaris 9 Installation CD-ROM; rather, the Solaris 9 Software 1 CD-ROM, which is bootable, should be employed. The suninstall program has the advantage of not requiring high-resolution graphics to complete installation: thus, a low-resolution monitor or terminal can be used. It requires a minimal amount of RAM, and allows you the greatest flexibility in configuring your system prior to installation (including internationalization). However, it does not allow you to install third-party software as part of the installation process, like the Web Start Wizard. The order of questions and procedures followed are generally the same as for the Web Start Wizard.
When installing Solaris Intel, using the suninstall method is more reliable than the Web Start Wizard, because it relies less on graphic cards and displays that may not be compatible with the Solaris X11 server.
