512 Mbytes of memory is insufficient to install the Solaris Express Developer Edition GUI installer. You need at least 768 Mbytes of memory to install the Developer release.
Workaround: Choose one of the following workarounds:
x86 systems: In the GRUB menu, choose the Solaris Express Serial Console ttyb installation option (#4). This option provides a text-based installation that works with 512 Mbytes of memory. This installation includes only the operating system and not the developer tools. You can add the developer tools after the installation.
SPARC systems: Use the following installation command:
ok boot cdrom - text |
This option also provides a text-based installation that works with 512 Mbytes of memory. This installation will include only the operating system, not the developer tools. You can add the developer tools after the installation.
For more information about these installation options, see the Solaris Express Installation Guide: Basic Installations.
