For the Operating System

If most or all of the options are selected during operating-system installation, OS/2 2.0 requires a partition with a minimum size of 30MB. If no options are selected, the basic components of the operating system require a 15MB partition.

If some options are selected, the required size of OS/2 2.0 varies between 15MB and 30MB. For example, if the Tutorial and Command Reference portions of the online documentation are not installed, 850KB less disk space is required. Each printer driver takes 250KB to 1MB disk space, so it is advisable to install only those needed for the installed printers.
