When all installable options are selected, OS/2 Version 2.0 requires 30MB of fixed disk space in which to install itself. Approximately 26MB is used by the operating system files and 4MB used in the initial SWAPPER.DAT file. This usage may be substantially reduced if some of the installable options are omitted. Users should ensure that the required amount of fixed disk space is available in their system.
If partitioning the fixed disk for multiple partitions, users should ensure that the partition into which OS/2 Version 2.0 is to be installed is of sufficient size to accommodate the operating system and required options. A recommended minimum partition size is 40MB.
Don't forget to plan for the appropriate amount of fixed disk space to hold the SWAPPER.DAT file. This file will grow rapidly when overcommitting the system resources (memory). Also, the \SPOOL subdirectory holds print jobs that have been spooled and are waiting to be printed. This subdirectory can quickly use up available disk space if large or complex print jobs are sent. The default path for the spool path is \SPOOL on the drive the operating system is installed on. The spool path can be changed by opening Spooler settings by selecting in turn OS/2 System from the Desktop, System Setup and Spooler.
Partitioning fixed disks for support of OS/2 Version 2.0 is also discussed in Boot Manager.
