Installing on 32MB systems

You can install SCO OpenServer on a system with only 32MB of RAM, subject to these caveats:

The installation procedure checks your system for available RAM and displays an error message if it is below the minimum requirements. You can choose to continue the installation even if your system currently has less than the minimum amount of RAM.
